My current web workload sits entirely on EC2 and I’m paying more each month while response times keep slipping. I want fresh eyes on the stack, so the engagement begins with a deep-dive audit: CPU, memory, database behaviour and network flow. Please capture every finding in a detailed, evidence-based report—graphs, screenshots, CloudWatch metrics, the works—so decisions are backed by data, not guesswork. Once the pain points are clear, I’ll need a redesign that balances cost and performance. Feel free to compare alternatives such as Lightsail or a move to managed services, but assume EC2 remains the baseline. The proposal should include an architecture diagram, projected monthly spend, and clear justification for each component. If we proceed to implementation, ...

Hi I will share the details with the shortlisted candidates. Thanks

I need an experienced Windows infrastructure engineer available 40 hours a week, Monday-to-Friday, 9 am–5 pm (my local time), for the next three to six months. Your day-to-day priority is hands-on maintenance and support: keeping our Hyper-V virtualisation platform, Active Directory, and Office 365 environment fully patched, optimised, and trouble-free while always thinking “security first” in line with a Zero-Trust mindset. Alongside the routine work you will also help me formalise and document best-practice configuration “by the book”, carry out small-to-medium migrations between tenants or hosts, and ensure Veeam backups are running cleanly. Regular system updates, performance monitoring, and swift issue troubleshooting are expected without prompting&mdash...

I’ve finished building a MERN-stack web application and now need it running smoothly in the AWS cloud. I don’t have any of the cloud pieces in place yet, so I’m looking for someone who can handle the full environment setup—from account configuration right through to production release. Here’s what I expect: • Containerise the existing React front-end and Node/Express back-end, then push the images to ECR. • Create an ECS (Elastic Container Service) cluster with tasks and services that scale cleanly. • Wire up networking: VPC, subnets, security groups, an application load balancer and HTTPS via ACM. • Automate deployment (GitHub Actions or similar) so each commit flows through to ECS with zero-downtime. • Store environment var...

I need a seasoned Zoom architect to walk me through every corner of our current deployment and then chart the cleanest path for folding our Cisco video-conferencing systems into it through the existing Hybrid Connector. Scope of the review – User management: roles, licensing tiers, provisioning flow, SCIM or SSO touchpoints. – Meeting configurations: templates, default policies, breakout settings, cloud recording rules. – Security settings: encryption posture, waiting-room logic, passcodes, data-retention policies. Once the audit is complete, I want a migration blueprint that shows exactly how each Cisco endpoint will register, what firmware or mode tweaks are required, and how to validate call quality end-to-end inside Zoom Rooms. Deliverables 1. Written asses...

Please provide a step-by-step solution or complete repair.

We are looking for a skilled network engineer to configure one Cisco FPR-1120 firewall. There is no internet connection config needed for this firewall as it is local network access only. I’ll provide anydesk and remote console access and a maintenance window when we’re ready. - Interfaces and IP address allocation ( Internal, External IPs must be on same scheme, like for inside network IPs should be to and outside network IPs should be to ). ( We do NOT different Internal, External IPs scheme, like for inside network IPs to and outside network IPs to ).

I am rolling out a small-to-mid scale infrastructure upgrade that combines low-voltage data lines with standard electrical cabling in the same facility. On the network side I need fresh runs of CAT6 (or better), clean terminations into patch panels, and basic router/switch configuration so the new drops light up immediately. Think wall-plate to rack, labelled, tested with a Fluke, and then a quick hand-off of the switch config file—Cisco or Ubiquiti CLI is fine as long as it’s documented. Parallel to that, I also need the electrical rough-in and final wiring for the endpoints you’ll be serving: new duplex outlets at each workstation, conduit where code requires it, and a tidy breaker panel entry. No heavy distribution work or UPS installs this round—just reliable b...

I have already stood up the Microsoft 365 tenant, assigned the user licences, purchased BitTitan seats and even created the MigrationWiz project. The only thing blocking me from pressing Go is an authentication error on the Google Workspace side. We’re authenticating with a Service Account— I tried recreating that account but the same error persists. What I need from you is straightforward: • Pin-point and correct whatever is mis-configured in the Google Workspace / BitTitan setup that is throwing the authentication error. • Validate the fix by running a successful test migration batch. • Once the connection is solid, complete the full mailbox and data transfer from Google Workspace to Microsoft 365 and confirm nothing is left behind. I will provide admin...

I’m setting up an EVE-NG environment dedicated to realistic enterprise-grade network simulation. The goal is to emulate the mix of routers and switches you would normally find in a corporate core-to-edge design, then use that sandbox for future testing and skill-building. Here’s what I need from you: • Deploy or validate the EVE-NG installation (community or PRO, whichever you recommend for this scope) on my virtualisation platform. • Import the relevant router and switch images, verify they boot cleanly, and apply any optimisation tweaks so the lab runs smoothly even under load. • Build an initial enterprise topology that includes core, distribution and access layers, complete with basic IP addressing and connectivity tests so I can hit the ground running....

I run a production system built on Jitsi Meet (Prosody, Jicofo, JVB) with Jigasi handling SIP calls. Without any recent configuration tweaks or version upgrades on our side, we have started seeing three consistent symptoms during phone-bridge sessions: poor audio quality, intermittent connection drops, and at times complete loss of transmitted audio. I have already combed through Jitsi, Jigasi, and general Linux logs but the underlying cause remains unclear. I now need a seasoned Jitsi expert who can step in, audit the stack end-to-end, identify the root problem, and apply a durable fix while keeping downtime to an absolute minimum. Key expectations • Deep diagnostic pass across Prosody, Jicofo, JVB, and Jigasi, including SIP integration details • Clear written report of ...

I have a five-year-old PHP-based web application that once served around 300 paying customers and had partnerships with firms like Qualcomm. The application is now static but is online; I want the full system running again so I can measure current market interest. You will receive the complete source code and its original MySQL database dump. The immediate goal is straightforward: review the codebase, resolve anything that prevents a clean build, prepare the list of third party APIs needed, and switch it to production with minimum downtime. No new features are required today; I simply need the existing functionality working end-to-end. Key checkpoints: • The built-in router integration (it handles client device routing within the app) has to be verified before go-live. •...

I need a technician for future issues like this: I run a mixed Windows 10, Windows 11, and Windows Server environment and critical domain issues are disrupting daily work. Top priority is restoring domain stability—users can’t authenticate, some PCs lose contact with the domain controllers, and several Group Policies refuse to apply. Once the domain is healthy, I also need help with a stubborn boot-loop on one workstation, fine-tuning Windows Defender Firewall rules, and checking a handful of other advanced Windows quirks that have crept in. You’ll have full remote access (VPN + RDP) and I’ll be available for live testing or quick reboots. Typical tools in play here are Active Directory DS, DNS, GPMC, Event Viewer, PowerShell, and Sysinternals; feel free to brin...

I’d like an experienced Palo Alto engineer to keep an eye on our firewalls through Panorama, handling day-to-day monitoring and rapid incident response entirely remotely. The core of the engagement is ongoing health-watch and swift resolution whenever an alert, log spike, or policy-related incident appears—no onsite visits, everything through Panorama, CLI or preferred tools such as Expedition, TAC, or Splunk if that speeds diagnosis. The workflow I have in mind is straightforward: you watch the dashboards, syslog feeds and health stats, jump in the moment something drifts from baseline, contain the issue, fix it, then send a short root-cause and remediation note so I can track what changed. If firmware, dynamic updates or policy tweaks are needed to clear the incident, you ...

Our production network is showing its age: users complain about frequent disconnections, sluggish throughput, and I have already spotted a few worrying security gaps. I need an experienced network engineer to jump in, isolate the root causes, and leave the entire environment stable and secure. Scope The job covers every layer that might be contributing to these symptoms—routers, switches, firewalls / security appliances, and even the cabling runs between closets. You’ll be expected to inspect configurations (Cisco IOS, Juniper, FortiOS or similar), test physical links, run packet captures with Wireshark or equivalent, and tighten any loose security rules you uncover. Deliverables • Clear root-cause report for each problem found • Corrected or optimised device ...

I need an experienced network engineer for a single full-day visit to my client’s facility. Your primary goal is to rack, stack, power up, cable, and provide console access for new routers, switches, and firewalls exactly as shown in our network diagrams. My remote team will handle all configuration after you confirm console reachability, so no advanced CLI work is required on site. You must arrive with your own standard toolkit—screwdrivers, cage nuts, patch cables, console lead, cable tester, and a laptop able to run console software—so you can work independently without borrowing equipment. While the network gear is booting, I’ll also rely on you for light hands-on support with user devices: verifying desktop or laptop imaging, reseating or swapping simple co...

I have a Raspberry Pi already running WireGuard, but the service still needs to be fully configured so it can shield my entire home network. My goal is to route every device on the LAN—phones, laptops, smart-TVs, IoT hubs, the works—through a single, rock-solid WireGuard tunnel for outbound traffic and for secure remote access when I’m away. The Pi is up, SSH is enabled, and WireGuard packages are present; what’s missing are the peer keys, proper , IP forwarding rules, firewall tweaks (iptables / nftables), and the final verification that traffic from any local client truly exits only through the encrypted interface. I’d also like a brief walkthrough on adding future peers so I’m not stuck each time a new gadget joins the house. When we’re done I...

I need help configuring 4 phones using VOIP.ms. This does not include setup of the Virtual Receptionist, which is complete. Ideal Skills and Experience: - Experience with Yealink T46S series phones and Polycom Phones. - Knowledge of VOIP systems - Ability to set up call routing and forwarding

I need Google Cloud Logging fully configured to ingest real-time syslog from both firewalls and routers on my network. The estate includes several firewall brands and models, all of which can point to a syslog target, so the solution must stay vendor-agnostic. Here is what I’m after: • Stand-up or fine-tune a log forwarder (Fluent Bit, rsyslog, or any proven alternative you prefer) that listens locally, receives the events, and reliably forwards them into Google Cloud Logging. • Lock the listener down so it will only accept traffic from a strict IP whitelist—this is the sole authentication method required right now. • Validate that messages from at least one firewall and one router reach the correct Log bucket with original timestamps intact and the proper r...

I keep hitting a connection-timeout message whenever I try to reach my PostgreSQL database from the terminal with psql. The database is part of a Dockerised backend; the application layer spins up fine, yet a direct CLI connection fails as though the server does not exist. I have not even confirmed whether the PostgreSQL container is actually running because I am unsure of the correct Docker commands to use or the places to look for port-mapping issues. What I need is straightforward: trace the reason the terminal session can’t find the server, bring the database online (or exposed) if it is down or mis-configured, and leave me with the exact commands or config edits required so I can repeat the process on other environments. Deliverables • Working psql connection from my lo...

Hi I will share the details with the shortlisted candidates. Thanks

I am preparing the first public release of the Node-based web service that powers and I need an experienced sounding board. Right now I mostly need advice, not hands-on coding, but the right person could easily grow into the primary developer and long-term technical lead for the project.

I’m ready to commission a full-scope wireless penetration test focused purely on uncovering vulnerabilities in our environment. The engagement spans everything that can ride our Wi-Fi: the access points themselves, the end-user laptops and mobiles that attach to them, and the underlying network infrastructure they ultimately reach. The technical stack here is a little unusual, so comfort with Kali Linux toolsets is essential, but you’ll also need to pivot into Java- and Python-based scripts and containerised tooling we already run in Docker. In other words, I’m looking for someone who can drop straight into the existing lab, fire up containers, customise scripts, and then carry that same skillset into the live environment once we move from staging to production. Deliver...

I’m currently running ActiveBatch Version 12 and need a smooth jump to the latest release without disrupting our production schedules. Alongside the core upgrade, I have to roll out and register well over ten new agents across our mixed Windows / Linux landscape. Because many of our workflows exchange files through GoAnywhere MFT, the job also includes validating that every post-upgrade transfer and dependency still fires correctly. To keep expectations crystal-clear, here’s what I consider a complete delivery: • Pre-upgrade audit, backup and rollback plan • In-place upgrade of the ActiveBatch master to the newest version supported by Advanced Systems Concepts • Deployment, configuration and health check of more than ten agents • Smoke tests on sam...

I am working on a research paper in the area of Wireless Sensor Network security and need a simple, runnable simulation model for Hello Flood attack detection. The work involves creating a small WSN simulation (10–50 nodes) using Cooja/Contiki or NS-3, where one or more malicious nodes perform a Hello Flood attack. A basic detection technique (threshold-based , energy-based , etc) should be implemented to identify the attacker. After creating the model, you should also explain and show basic performance metrics such as detection accuracy, precision/false positives (if possible), and energy consumption, so the results can be compared with existing research papers. The focus is on academic experimentation, not a complex or commercial system.
