You will get Backend Audit, Bug Fixing & Performance Optimization
Project details
Is your application slow, unstable, or full of unresolved issues?
I’m a Senior Full-Stack & Backend Developer with 9+ years of experience working on real-world, business-critical systems across ERP, healthcare, finance, and enterprise platforms.
This project is designed specifically for clients who already have a system and need an expert to audit, fix, and optimize it. I specialize in understanding existing codebases, identifying performance and architecture problems, fixing critical bugs, and stabilizing backends built with Laravel, Node.js, NestJS, and modern web stacks.
You will get a focused backend review, real fixes (not just advice), performance improvements, and a clear summary of what was done and what can be improved next.
If your system is slow, messy, or difficult to maintain, I can help bring structure, performance, and reliability to it.

About Punith
Senior Full-Stack Developer | Laravel, Node.js, React
Bengaluru, India - 1:27 pm local time
I specialize in fixing, improving, and scaling existing applications — not just building demos from scratch. Most of my work involves understanding complex systems, cleaning up backend logic, optimizing performance, and building reliable internal tools and dashboards that teams actually use.
🔹 What I help clients with:
• Fixing bugs and stabilizing existing Node.js / Laravel / MERN applications
• Backend & API development and third-party integrations
• Performance optimization (slow APIs, heavy queries, reports, large PDFs)
• Internal dashboards, admin panels, and workflow systems
• Database design & improvement (MySQL, PostgreSQL)
• Converting Excel/manual processes into scalable web systems
In my full-time role, I regularly work on large production platforms involving ERP modules, reporting systems, CI/CD pipelines, and complex business logic. I’m comfortable jumping into existing codebases, understanding them quickly, and delivering practical, production-ready solutions.
I usually start with a small paid audit or task, so you get clear visibility into system issues, improvement opportunities, and next steps before committing to larger work.
If your system is slow, messy, unstable, or hard to maintain, I can help bring structure, performance, and reliability to it.
