About this gig

Note: Please discuss the issue before placing the order.


Facing bugs, crashes, or broken features? I am a Full Stack Developer specializing in deep-level debugging. My goal isnt just a fast patchits identifying the root cause and delivering a stable, long-term solution for your application.


I bridge the gap between "broken code" and "production stability," ensuring your platform is secure, optimized, and user-ready.


What I Resolve & Fix:

  • Frontend: UI glitches, React hooks, Tailwind responsiveness, and JS bugs.
  • Backend: Node.js/Express crashes, API failures, and server logic.
  • Database: MongoDB/SQL errors, slow queries, and data integrity.
  • Auth & Security: JWT/OAuth loops, form failures, and permission bugs.
  • Deployment: Resolving build errors on Vercel, Netlify, and AWS.


Why Choose Me?

  • Root Cause Fix: I target the source so the bug doesnt return.
  • Clean Code: Optimized, maintainable fixesno "spaghetti" code.
  • Security-First: Ensuring fixes don't create new vulnerabilities.
  • Tested Delivery: Every fix is rigorously tested before delivery.


Workflow: Analysis -> Root Cause Fix -> Testing -> Deployment.
