Redis Jobs

A high-level AWS specialist is needed to migrate 30 WordPress sites from a traditional leased server to AWS Lightsail. This is not a "simple" migration; it requires a strategic split-infrastructure setup for an upcoming app launch. This is the first step in a series of projects; successful and timely work will lead to additional opportunities. Three of these sites will require a GitHub deployment workflow, so familiarity with Git in a WordPress environment is required. The Project: Consolidation: Move 29 low-traffic/static sites onto a shared, cost-optimized Lightsail instance. VIP Setup: Create a standalone, high-performance Lightsail environment for a flagship domain () targeting users in CA and MI. Performance: Implement Redis object caching and Lightsail CDN for the flags...

Our real-time data platform needs a rock-solid proxy layer that can move huge volumes of HTTP and SOCKS5 traffic with minimal latency. The immediate focus is designing and automating a high-concurrency architecture—from the Squid clusters themselves to the surrounding network and IP allocation logic—so that new nodes come online in seconds and stay performant under sustained load. Key components of the engagement • A web-based proxy panel that provisions, monitors, and rotates IPs automatically, exposing a clean API for our backend services. • Fully scripted Squid deployments on Linux, container-ready (Docker) but not container-bound, with Redis or similar caching where it measurably improves throughput. • Traffic distribution and fail-over policies tuned ...
