I build and ship production-ready web applications end-to-end, from responsive frontend interfaces to scalable backend APIs and database architecture.
My core stack is Next.js, TypeScript, React, Node.js/Express, PostgreSQL, and MongoDB. I've integrated live payment gateways (Monnify, Stripe), built secure authentication systems using JWT, OAuth, and AWS Cognito, and deployed applications on Vercel and AWS.
Projects I've shipped include a fintech rotational savings platform with automated payment processing and KYC verification, a blockchain-based event ticketing system with NFT minting on Hedera, and a full-featured inventory management system with role-based control and reporting.
What makes working with me different: I write clean, maintainable code, communicate clearly throughout the project, and deliver work that is actually production-ready — not just a demo. I work well within existing codebases and can step into ongoing projects without extensive hand-holding.
Services I offer:
- Full stack web application development
- REST API design and development
- Frontend development with Next.js and React
- Payment gateway integration
- Authentication and user management systems
- Database design and optimization
- E-commerce and SaaS platform development
