Senior Software Engineer
I build scalable, cloud-native web applications and geospatial data platforms.
About
I'm a senior software engineer with over five years of experience designing and shipping full-stack web applications. My focus is on building scalable, cloud-native systems with TypeScript, Python, React, Next.js, and FastAPI — the kind of platforms that have to stay reliable as users, datasets, and feature surfaces grow.
Currently, I'm a Senior Software Engineer at xMap, where I lead engineering on a geospatial data marketplace and a location intelligence platform. I designed the multi-tenant AWS architecture, built Stripe-powered access provisioning, and migrated the stack to serverless — cutting infrastructure costs by 20% and deployment time by 50%.
Previously I worked at Turing, Simply Zibra, and Decision Labs on everything from Deck.gl mapping annotation tools to Flutter payment apps and Ruby on Rails platform rewrites. I lean on test-driven development, mentor early-career engineers, and care a lot about getting CI/CD, observability, and authentication right the first time.
I hold a BE in Software Engineering from NUST, Pakistan. Reach me at usman.haider.developer@gmail.com — I'm always open to interesting problems.
Experience
2023 — PRESENT
Lead engineering on studio.xmap.ai (geospatial data marketplace) and polygon.xmap.ai (location intelligence). Built multi-tenant AWS architecture, Stripe checkout, Cognito auth with MFA, and Lambda workflows. Migrated to serverless — cut infra costs by 20%.
