Full-Stack Website Enhancements

My production site has grown steadily and now needs an experienced full-stack hand to keep it running smoothly while we roll out new capabilities. The core stack is PHP on the back end, with a few performance-critical modules written in C/C++ and a small Go service that handles real-time data.

Where I need you most right now is on two fronts:
• Tracking down and eliminating performance bottlenecks that occasionally slow page loads or spike CPU usage.
• Designing and shipping the next round of features without destabilising what’s already live.

You will have direct access to the existing codebase, test environment, and a clear ticket list. I handle product decisions and UI/UX; you keep the engines humming. Solid experience diagnosing tricky bugs, profiling server-side code, and writing clean, maintainable PHP is essential. Familiarity with C/C++ extensions and Go micro-services will let you move quickly across all layers of the app.

When you reply, focus on your experience tackling similar mixed-language projects—especially anything that involved both optimisation and new feature delivery in production. Links or brief summaries are perfect; no need for a full proposal at this stage.

If we’re a good fit, we’ll start with a small milestone (critical bug fixes) and move on to larger feature sprints. Looking forward to hearing how you’ve solved problems like these before.
