Project details
Is your website or app throwing errors, crashing, or just not behaving the way it should?
I'll find the root cause and fix it — fast, clean, and without breaking anything else.
WHAT I CAN FIX:
✔ React / Next.js bugs (UI glitches, broken components, routing issues, hydration errors)
✔ Node.js / Express backend errors (API failures, server crashes, middleware issues)
✔ MongoDB / Mongoose issues (schema errors, query bugs, connection problems)
✔ API integration issues (REST, third-party APIs, OpenAI / LLM integrations)
✔ Authentication & CRUD bugs
✔ Deployment/build errors (Vercel, Render, Netlify, etc.)
HOW IT WORKS:
1. Send me your error message, screen recording, or repo access
2. I diagnose the issue and give you a quick summary of the cause
3. I fix it, test it, and explain what was wrong (in plain English)
4. You get working code + a short note so it doesn't happen again
WHY WORK WITH ME:
I'm a full-stack MERN / Next.js / React Native developer who also builds AI-integrated
apps from scratch — so I don't just patch the symptom, I understand the whole system
your bug is living in.
Send me the details in the requirements box and I'll confirm the timeline before starting.

You're in the right place.
I'm 𝐌𝐚𝐡𝐧𝐨𝐨𝐫, a Full-Stack Developer specializing in MERN Stack, Next.js, React Native, and 𝐀𝐈 & 𝐋𝐋𝐌 𝐢𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧.
I help businesses transform ideas into fast, scalable, and user-friendly applications. Whether you're building a new product from scratch or improving an existing one, I focus on delivering clean, maintainable code that supports your business goals.
Currently, I work as a 𝐑𝐞𝐚𝐜𝐭 & 𝐑𝐞𝐚𝐜𝐭 𝐍𝐚𝐭𝐢𝐯𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 on a production B2B platform for visa and sponsorship management. My day-to-day work includes developing admin dashboards, integrating REST APIs, building reusable components, and delivering features used by real users.
Here's how I can help:
• Full-stack web applications with MERN Stack and Next.js
• Cross-platform mobile applications with React Native
• AI-powered features using OpenAI and Google Gemini, including chatbots, document and image analysis, and workflow automation
• REST API development and third-party API integration
• MongoDB database design and backend development
• Authentication using JWT and Firebase
• Responsive, modern user interfaces with React, TypeScript, and Tailwind CSS
• Deployment on Vercel, Render, and Netlify
To demonstrate my skills, I ranked 861𝐬𝐭 𝐨𝐮𝐭 𝐨𝐟 1,773 participants in the 𝐇𝐚𝐜𝐤𝐞𝐫𝐑𝐚𝐧𝐤 𝐎𝐫𝐜𝐡𝐞𝐬𝐭𝐫𝐚𝐭𝐞 𝐇𝐚𝐜𝐤𝐚𝐭𝐡𝐨𝐧, where I built a𝐦𝐮𝐥𝐭𝐢𝐦𝐨𝐝𝐚𝐥 𝐀𝐈 𝐩𝐢𝐩𝐞𝐥𝐢𝐧𝐞 for automated damage claim verification. I've also developed projects including an AI Code Reviewer, an Autonomous Research Agent, a Real Estate Management Platform, and several other full-stack applications showcased in my portfolio.
I care about writing code that's easy to maintain, not just code that works today. That's what I aim to deliver on every project: solutions that are scalable, reliable, and built to last well past launch.
If you're looking for a developer who communicates clearly, delivers quality work, and genuinely cares about your project's success, I'd love to hear about your idea.
