Building products
end to end

I am a Flutter and full-stack developer with nearly 3.5 years of experience building and shipping cross-platform mobile and web applications. I work across the stack — from Flutter and React frontends to Flask/Python backends and PostgreSQL — and I communicate clearly with clients and teams.

I work independently, stay proactive, and move fast without sacrificing code quality. I am based in Lahore, Pakistan, and open to remote roles that fit this profile.

Client collaboration

Requirements, meetings, progress updates, and turning business needs into technical plans and shippable software.

Mobile & BLE

Cross-platform iOS and Android with Flutter, including BLE device discovery, pairing, and platform-specific edge cases.

What people say

LinkedIn recommendations plus feedback from clients I've shipped products for.

View on LinkedIn
Our old site did not reflect the level of care we provide, and updating it kept falling off my list. Mudabbir took the time to understand how patients actually find and book with us, then delivered a clean, professional site that is easy to maintain. Communication was straightforward, timelines were realistic, and several colleagues have already commented on how polished everything looks.
