You will get REST API Development for Mobile Apps & Frontend Integration
Project details
Your mobile app or frontend needs reliable data, fast. I build production-ready REST APIs with Node.js and Express that deliver consistent performance and bulletproof security—so your frontend team can build with confidence and your users get instant responses.
This isn't just about connecting databases to endpoints. It's about creating a scalable backend architecture that handles authentication, authorization, data validation, error handling, rate limiting, and caching automatically. You get clean API design that follows industry standards and makes integration straightforward.
What makes this API development different? I focus on developer experience AND production readiness. You receive complete API documentation, Postman collections for testing, clear error messages that actually help debug issues, and organized code that future developers will thank you for.
The technical advantage? MongoDB or MySQL for flexible data storage, JWT authentication for secure access, comprehensive logging for debugging, and optimized queries for fast response times. Your API will handle traffic spikes gracefully, integrate with other services easily, and scale as your user base grows.

Job Success
Gujranwala, Pakistan - 4:31 am local time
Most recently, I've been the lead developer on Listed KY, a live classified-ads marketplace built on Next.js and MongoDB with server-side rendering, real-time buyer-seller chat over Socket IO, and a search layer built on aggregation pipelines. It's in production, and I still maintain it.
WHAT I BUILD
Web applications (React and Next.js)
- Marketplaces, directories, and classified-ad platforms
- SaaS dashboards with authentication, user roles, and data visualization
- Booking systems, CRMs, and internal admin tools
- MVPs for founders who need to launch and validate quickly
APIs and backend (Node.js)
- REST API development and documentation
- Third-party integrations: Stripe, payment gateways, external data providers
- Real-time features using Socket IO — live chat, notifications, instant updates
- Database design in MongoDB and PostgreSQL
WordPress
- Headless WordPress with a Next.js or React front end
- Custom theme development from Figma or design files
- WooCommerce stores with custom checkout and payment flows
- Speed and Core Web Vitals optimization — sub-2-second load times
- Malware removal, security hardening, and rescuing broken or hacked sites
- Migrations, plugin customization, and ongoing maintenance
AI integration
- OpenAI API features: chatbots, content generation, automated support
- Adding AI capability to applications that already exist
WHY CLIENTS KEEP ME
Fixed scope and fixed price before we start. You get a written plan with milestones and a delivery date before any code is written, and I don't send surprise invoices.
Daily written updates on active work. You will never wonder where things stand or whether I've disappeared.
Code you actually own. Clean repository, readable structure, documentation, no proprietary lock-in. Any developer can pick it up after me.
Two weeks of free post-launch fixes on everything I ship.
I'll tell you when you don't need me. If a WordPress plugin solves your problem in an afternoon, I'll say so rather than quoting you for a custom build.

30 completed contracts on Upwork with a 100% Job Success Score.

LET'S TALK
Message me with what's broken or what you're trying to launch - the problem, not the spec. I reply within a few hours with an honest read on scope, timeline, and whether I'm the right person for it. If I'm not, I'll tell you that too.
