    Hi everyone, I’m looking for a sharp full-stack developer to help me polish and finalize a custom API gateway platform. The core idea is based on the Wei-Shaw/sub2api repo—we’re basically turning web account subscriptions into a usable, unified API. Before you read any further, please watch this short video I put together: It walks through exactly what I need. Please do not apply until you’ve watched the whole thing, as I ask about a specific detail from it below. The Technical Headache: Concurrency This isn't just a basic CRUD app. The biggest challenge here is handling heavy multi-request traffic. I need someone who actually knows how to manage concurrent requests without dropping connections, leaking sockets, or getting banned by rate limits. You'll...

    I already have a RunPod GPU instance waiting and need a clean, production-ready setup of an open-source large language model that will power a technical-support chatbot.

    My GoDaddy-registered domain recently lapsed, and the registrar has swapped in their default parking nameservers. Before the expiry, the domain was pointing to a shared hosting account set up about five years ago. Unfortunately, the original developer is unreachable, I don’t recall which host we used, and I have no legacy emails or paperwork that list the settings. The job is to research and identify the exact nameserver pair (or set) that was active immediately prior to GoDaddy’s parking change.

    We have a brand-new domain on a fresh Hostinger mail server and every message we try to send to Gmail is immediately refused. The domain itself checks out clean and I ran the usual blacklist scans on both the domain and server IP without finding anything suspicious, yet Google still bounces even a single manual test email. At the moment we send only occasional marketing messages—nothing high-volume—and I’m not even sure whether reverse DNS is correctly configured on this server. SPF, DKIM and DMARC may also be missing or incomplete; if they are, I’ll need them set up properly.

Here’s the flow I have in mind: first, you will remotely review the existing topology, switch configurations, VLAN design, and cabling maps. After running traffic captures and SNMP or NetFlow baselines, you’ll present a concise report showing where bandwidth is wasted or mis-prioritised. Once we agree on the findings, you’ll put the fixes in place—whether that involves QoS adjustments, firmware upgrades, or smarter port-channeling—and then verify the improvement with fresh metrics.

    I run a small, private Survival Minecraft world that usually tops out at ten friends during peak evenings. I’d like someone to take over the technical and community-facing chores so I can focus on simply playing. The immediate priorities are: • Plugin setup and upkeep – install, configure, and keep updated essential Paper/Spigot plugins (economy, land-claim, grief prevention, permissions, chat, and any quality-of-life add-ons we agree on). • Performance tuning – optimise the JVM flags, Paper config, and hardware allocation to keep TPS rock-solid even when redstone farms or exploration spike our tick load. • Light moderation – help enforce basic rules, roll back griefs with CoreProtect-style tools, and maintain a friendly chat atmosphere; no heav...

    I have Acelle Mail v4.2.0 installed and a cluster of 20 VPS servers already running Postal as the SMTP backbone. In total, 300 sending domains are ready to rotate. What I need now is the layer that ties everything together—a custom domain-management module built into (or cleanly integrated with) Acelle that will let me run large-scale, cold-email campaigns safely and predictably. Key elements I expect from this module • Warm-up scheduler, blacklist monitoring, and domain-rotation management are all mandatory features. • The warm-up scheduler should work in a hybrid fashion: the system proposes an automatic ramp-up plan based on my predefined rules, I approve or adjust, and only then does it execute. • Blacklist monitoring must track spam complaints, bounce rates...

    My office relies heavily on a mixed environment of Windows workstations and a growing fleet of Ubuntu machines, so day-to-day stability is critical. I need someone who can drop straight into real-world troubleshooting—swapping out failing laptop drives, cleaning up driver issues, reinstalling an OS when it is faster than patching, and keeping every system fully-patched and backed up. The immediate priority is our Ubuntu-based infrastructure: fresh server installations, user management, and routine CLI-level administration. Alongside this, I have several hardware firewalls that must be given a clean, BASIC setup—standard rules, NAT, limited port exposure, and a sanity check on default credentials. Networking touches almost every ticket that crosses my desk. You will be the...

    My site feels sluggish, images take too long to appear, and I am running into storage-related limits that keep new photos from uploading smoothly. I want the whole experience to feel snappy and hassle-free again. The core of this job is performance tuning. I need three concrete upgrades: • Optimize images so every picture is compressed without noticeable quality loss • Minimize code and scripts—strip unused CSS/JS, combine and minify what stays • Improve server performance through smarter caching, database clean-up, and any other proven tweaks you recommend Alongside the speed work, please diagnose and clear the issues that are blocking or slowing photo uploads and eating up server space. Once you are done, I expect visibly faster page loads on both mobile and...

    I need a robust socket-based system written in Python that can manage dozens (eventually hundreds) of simultaneous client connections. Each client will push mixed data (text and binary) to the server every few minutes. The server must: • Accept and keep persistent TCP connections, identify each client by its IP/port, and store that mapping in memory for quick callback. • Route outbound messages so I can speak to any individual client on demand—think targeted commands, acknowledgements, or config updates. • Insert every payload into a customer-specific MySQL schema (one database per customer, tables you define). • Create a rolling log file per client capturing connection events, payload metadata, and outbound commands. I’m fine with your preferred con...
