A short // who am i

I'm a Senior Mobile Engineer based in Peshawar, Pakistan, with 8+ years shipping cross-platform apps in Flutter, Dart, React Native, Kotlin, and Swift. Started my Flutter journey in November 2018 and have been building production-ready applications ever since.

I focus on complex, high-performance apps — particularly in fintech, crypto, travel, and e-commerce. Deep experience with blockchain / Web3 integrations, KYC flows (Sumsub), and clean architecture for codebases that need to scale. I've worked with clients across Europe, the Middle East, and the US.

Currently CTO at HugeOne.io and shipping production Flutter at Inwall. When I'm not coding, I contribute to the Flutter community and mentor fellow developers.

What clients say

5★ rating across 50+ Fiverr projects. A few representative quotes below.

★★★★★

Amjad shipped our MVP in six weeks and the code was the cleanest hand-off I've ever received. He flagged edge cases we hadn't thought of and just fixed them.

SM
Sarah M.
Founder · Fintech startup
★★★★★

We came in with a half-baked spec and walked out with a production app on both stores. Communication was excellent throughout — felt like having an in-house engineer.

JK
James K.
Product Lead
★★★★★

Hired Amjad on Fiverr for a one-off and now he's our go-to for everything Flutter. Reliable, fast, and the polish on the UI is consistently exceptional.
