What I'm looking for

I'm looking to build scalable web, mobile, and data-driven products where I can improve user experiences, system performance, and business outcomes across fintech, e-commerce, or public-sector platforms.

I've built marketplace, fintech, and public-sector products at Rayn Group, Droppe, Retailo Technologies, and GrocerApps. At Rayn Group, I'm architecting Pakistan's national disaster recovery platform for the Ministry of Planning & Development across NestJS, React, Flutter, PostgreSQL, GIS, and Docker infrastructure.

At Droppe, I delivered saved products for 10,000+ users, analytics reporting with DBT and BigQuery that lifted campaign ROI by 25%, and a Google Retail API carousel that increased upsell by 15%. I also helped build microservice-based data APIs serving 100,000+ daily users.

I've integrated payment gateways handling high-volume transactions, launched subscription and mobile commerce products, improved application performance by 200%, and built analytics dashboards and AI-driven recommendation systems that improve engagement, retention, and operational decisions.
