Project description:
"My production web application is struggling with several persistent bugs and noticeable slow-downs that are now affecting users in real time. I need a full-stack developer who can jump straight into the existing codebase, trace the root causes, and deliver clean, well-documented fixes that restore stability and speed.

The stack is a typical modern SPA supported by an API layer and a relational database. You’ll have access to the private Git repository, staging environment, and current error logs. I’ll point you to the most critical endpoints and UI flows where users are currently hitting 4xx/5xx responses or experiencing load times well above acceptable thresholds.

Deliverables
• Comprehensive issue report outlining each bug or bottleneck, its diagnosis, and planned solution.
• Clean pull requests for every fix, with clear commit messages and inline comments.
• Performance benchmarks before and after your optimizations, demonstrating a measurable improvement in page load and API response times.
• A brief hand-over note summarising key changes and any follow-up recommendations.

Acceptance criteria
• No new errors introduced during regression tests.
• Critical pages load in under two seconds on staging using Lighthouse.
• All unit and integration tests pass in CI.

I’m ready to give prompt feedback and can deploy your patches to staging as soon as they’re submitted. Looking forward to a focused, results-driven collaboration." (client-provided description)
