What I do
I build complete web applications end to end: database design, REST APIs with authentication, responsive React and Next.js front ends, payment-gateway integration and deployment on AWS. On top of that I build the AI layer: AI agents that answer customers and book appointments, chatbots trained on a company's own documents, and AI data processing inside business systems.
My work has gone into government, healthcare, fintech, retail and tourism products, including a Gilgit-Baltistan government tourism portal, a diagnostics platform, a multi-tenant point-of-sale system and the Agentra AI agents platform.
Experience
React and NestJS features across four live platforms (DTS, PROMIS, IMS, UXL POS), payment-gateway integration and AWS deployment.
Automated trading platform from database design to deployed REST API, NestJS/Node.js API optimisation, and work on the Agentra AI agents product.
Responsive UI components with HTML, CSS and JavaScript, and cross-browser bug fixing.
