Pages that take 3 seconds to load, an API that times out under traffic, a dashboard that freezes every morning: most of the time the cause is one or two things, not the whole codebase. I find them and fix them.
In my last job I took a document-processing platform used by 60+ enterprise clients down to under 200ms, mostly through profiling and query work, not new servers.
What I do
- Profile the slow pages or endpoints and find the real bottleneck
- Fix slow SQL queries: indexes, N+1 queries, query rewrites (MySQL, PostgreSQL, SQL Server, MongoDB)
- Add caching where it pays off (Redis or in-memory)
- Frontend fixes: bundle size, images, lazy loading, render blocking
- A short before/after report with the numbers
Stacks: Node.js, Laravel/PHP, Java/Spring Boot, Python, React, Vue, Angular.
$45 covers one slow page or endpoint (diagnosis + fix). Bigger systems: tell me what's slow in LaborX chat and I'll send a fixed quote. Payment through LaborX escrow.
