About Obaid
Full Stack Developer | MERN Stack, Next.js, Ruby on Rails | AI & LLM
Lahore, Pakistan - 2:18 am local time
I’m a full-stack engineer specializing in stepping into existing Next.js, React, and MERN stack codebases to fix bugs, refactor fragile code, and add custom features. Whether you need an AI-generated prototype stabilized, a Figma design turned into a responsive UI component, or backend API tweaks, I make sure your app becomes clean, reliable, and production-ready.
Instead of trying to sell you an expensive full rebuild, I focus on fixing what’s broken, optimizing performance, and adding the exact customizations you need without breaking existing functionality.
Core stack:
- React.js, Next.js, TypeScript, Node.js, Express.js, Rails
- PostgreSQL, MySQL, MongoDB, Firebase
- REST APIs, JWT/OAuth authentication
- OpenAI/LLM API integration, Vercel, serverless deployments
What I bring:
- Cleaning, fixing, and refactoring fragile code generated by AI.
- Fixing state management bugs, layout issues, and broken API connections.
- Converting Figma designs into responsive components and tweaking existing UI.
- Adding new custom features or modifying existing app functionality.
- Integrating REST APIs, third party services, and LLM features.
- Refactoring code for better perfromance adn maintainability.
If your web app or prototype got you part of the way there, I’ll take it the rest of the way, clean, stable, and ready for real users.
Send me a message with what’s broken or what you need customized, and let’s get it fixed!
