You will get audit and fix bugs in your Next.js or React application
Project details
Is your Next.js or React app broken, slow, or behaving unexpectedly?
I help developers and businesses fix bugs, resolve performance issues, and stabilize existing web applications — so your app works the way it should.
I've maintained production-grade Next.js applications used by real organizations, and I've done performance work that reduced API response times from ~2–3 seconds to under 400ms.
What you'll get:
• Root cause identified and fixed — not just patched
• Clean, readable code changes with clear explanation
• Written summary of what was wrong and what was changed
• Peace of mind that the fix won't break something else
I work well with:
• Next.js / React applications
• Node.js + Express backends
• PostgreSQL databases
• REST API issues
• TypeScript codebases
• Tailwind CSS layout bugs
How it works:
You share your codebase or relevant files
I reproduce and diagnose the issue
I fix it cleanly and explain exactly what changed
You review and approve
Have more than one issue? The Standard or Premium tier covers multiple bugs with a written report of all findings.

Purworejo, Indonesia - 11:15 am local time
I am a Bug Fix Specialist with 1+ years of experience across Software House, Government, and Philanthropy industries. I am highly proficient in fixing, maintaining, and customizing existing codebases..
What I can help with:

• Performance Optimization : responsiveness, query optimization, SEO, and general code cleanup
• Feature Enhancement : new functionality added cleanly into your existing code, client or server side
Recently, I worked at Yakesma as IT Developer where I consistently resolved bugs within the Internal ERP, completing 50+ bug fixing tasks with my own robust workflow and reducing API response time from 2–3 seconds to under 400ms on a government-scale platform.
Why you should choose me :
• Familiar with legacy and existing codebases, I navigate unfamiliar code quickly

Review & Reproduce
I'll review the codebase and information you've provided, then reproduce the bug in my local environment to understand the exact behavior.
