Senior Software Engineer
I build scalable web platforms with TypeScript, React, Python, and AWS — from geospatial tools to payment systems.
About
I'm a senior software engineer with over five years of experience shipping scalable, full-stack products. I work across the stack — TypeScript and React on the frontend, Python and Node.js on the backend, and AWS, Firebase, and GCP for the infrastructure that holds it all together.
Currently, I'm at xMap, where I lead engineering on two geospatial platforms — Studio, a marketplace for location datasets, and Polygon, a location-intelligence tool. I drove the migration to a serverless architecture that cut infrastructure costs by 20%, integrated Stripe for transaction processing, and shipped a multi-tenant Cognito + Lambda auth flow across staging and production.
Previously, I built mapping annotation tooling at Turing with Deck.gl and GraphQL, shipped a Flutter-based payments app at Simply Zibra, and spent three years at Decision Labs modernizing legacy applications with React, Node.js, and Ruby on Rails — all under a strict TDD discipline. Reach me at usman.haider.developer@gmail.com.
Outside of shipping code, I'm reading about distributed systems, mentoring earlier-career engineers, and tinkering with side projects on GitHub.
