I build scalable React and Node.js products from concept to production.

I've built production booking platforms, marketplaces, healthcare tools, fintech systems, and media applications across Codezeros Technology, Excellent Webworld, and Tops Infosolutions. I own end-to-end delivery, from Node.js/NestJS APIs and database design to React.js and Next.js frontends.

I improve performance through Redis caching, query optimization, SSR, code splitting, and component architecture, including raising Clarity Co-operative's Core Web Vitals score from ~55 to ~95. I've also mentored junior developers and delivered integrations spanning Stripe, AWS SQS, Firebase, Socket.io, Twilio, and SendGrid.
