Support - Bug Fixing & Optimization

Something's not working and your users are feeling it. Maybe pages take forever to load, errors keep popping up in production, or your Lighthouse scores are in the red. I jump in, diagnose the root cause, and fix it — fast. No band-aids. I solve the actual problem and make your app faster, more stable, and easier to maintain going forward.

What's included

Every bug fixing & optimization engagement includes these core capabilities — tailored to your specific requirements.

Critical bug diagnosis and permanent resolution

Performance audits with Core Web Vitals analysis

Memory leak detection and garbage collection fixes

Slow database query identification and optimization

Security vulnerability scanning and patching

Codebase refactoring for long-term maintainability

Lighthouse score improvement — targeting 90+ across the board

Load testing to find and eliminate performance bottlenecks

How it works

A structured, transparent process from initial requirements to production deployment.

01

Audit & Diagnosis

I review your codebase, error logs, performance metrics, and infrastructure setup to pinpoint exactly what's going wrong and why.

02

Priority Assessment

Not every bug is created equal. I rank issues by severity and user impact, then lay out a clear action plan so you know what gets fixed first.

03

Fix & Optimize

I apply targeted fixes and performance improvements — each one tested thoroughly to make sure I'm not creating new problems while solving old ones.

04

Verification & Report

Once fixes are live, I validate everything in production and hand you a detailed report showing what changed and how much performance improved.
