You will get your Next.js or Node.js app fixed, finished & stable
Top Rated
Project details
Inherited a messy codebase? Developer went quiet? App breaking in production? I take over unfinished and unstable projects and get them working.
I'm a Top Rated, 100% Job Success full-stack developer who specializes in jumping into existing code, figuring out what's actually wrong, and fixing it without breaking everything else. I've rescued half-built SaaS products and taken them all the way to launch, and clients tend to keep me on afterward.
I can help with:
• Debugging production errors and crashes
• Finishing features a previous developer left incomplete
• Fixing database and performance issues
• Cleaning up and stabilizing a shaky codebase
• Getting your app deployed and launch-ready
I work in Next.js, React, Node.js, TypeScript, and Python. Send me the repo or the error and I'll tell you what's going on and how I'd fix it before you commit.

Job Success
Lahore, Pakistan - 4:39 pm local time
I build and scale SaaS platforms end to end: Next.js and React on the front, Node.js and Python (FastAPI/Django) on the back, with Stripe, PostgreSQL, and AWS behind them. The kind of product that doesn't break after launch.
If it involves APIs, dashboards, subscriptions, integrations, or AI features, I've probably built it before.
What I Build Most Often
• SaaS platforms (multi-tenant architecture)
• Backend APIs (FastAPI, Django, Node.js/Express)
• Integrations (OAuth, webhooks, third-party services, CRMs)
• Automation & background workers
• Analytics dashboards & admin panels (React / Next.js)
• Data processing pipelines
• Cloud deployments on AWS
Why Clients Hire Me
Many projects fail after MVP because the backend wasn’t designed for growth.
I design for:
1. clean architecture
2. predictable scaling
3. maintainability
4. faster future features
So you don’t need to rebuild in 6 months.
Recent Work
✔ Built medical platform MVP (Node.js + React), production ready
✔ Designed military social platform infrastructure (Flask + AWS + Docker)
✔ Created organization-wide email compliance & analysis system (OAuth integrations)
✔ Built IoT monitoring platform with real-time device data ingestion
✔ Developed automation workflows & analytics dashboards
Tech Stack
1. Backend
Python (FastAPI, Django, Flask)
Node.js (Express, NestJS)
REST APIs, Webhooks, OAuth
2. Frontend
React, Next.js, Vue
Tailwind, Material UI
3. Data & Infrastructure
PostgreSQL, Redis, MongoDB
AWS, Docker, CI/CD
Large dataset processing & reporting
If you need someone who can own both the architecture and implementation, message me before hiring multiple developers.
