Performance Fix

App running slow?
I'll find the bottleneck.

I profile it, find the actual problem (not guess), fix it, and show you the before/after numbers. Evidence-based optimization.

Common Scenarios

When to call me

Pages take forever to load

Users are bouncing. Your analytics show terrible load times. The team that built it isn't available to diagnose it.

It got slow as you grew

Your app worked fine until you got more data or users. Now everything crawls. Classic scaling problem.

API responses are timing out

Endpoints are taking too long. Users see spinners or errors. You need someone to find the bottleneck.

You've tried optimizing but nothing helped

Thrown caching at it, compressed images, upgraded servers. Still slow. Need fresh eyes from someone who's seen this before.

What I Fix

Performance issues I solve

Database

Slow queries, missing indexes, N+1 problems

Frontend

Render blocking, bundle size, hydration issues

API

Slow endpoints, inefficient data fetching, caching

Infrastructure

Server config, CDN setup, scaling issues

Example

Dashboard took 10+ seconds to load

The situation: Main dashboard had become unusably slow. Enterprise clients threatening to cancel. The freelancer who built the app had moved on. Throwing more server resources at it didn't help.

The outcome: Found a single query scanning millions of rows without an index. Added proper indexing. Dashboard now loads in under a second.

“We thought we'd need to rebuild everything. Turns out it was fixable in a day.”

FAQ

Common questions

How do you find the problem?

I profile the full request lifecycle - not guess. Browser devtools, database explain plans, APM tools. I find where the actual time is going.

How much faster will it be?

Depends on what's wrong. I've seen 10x improvements from fixing database queries. You'll get before/after benchmarks as proof.

What if it's a fundamental architecture problem?

I'll tell you honestly. Sometimes the fix is quick, sometimes it needs bigger changes. You'll know the options before committing.

Do you work with [my tech stack]?

React, Node.js, Python, PostgreSQL, MongoDB, Redis - most modern stacks. Performance principles are universal.
