What I'm looking for

I'm open to remote opportunities (UTC+5).

At Sofy.ai, I work on the platform behind a cloud of 200+ physical devices across 20+ farms running enterprise mobile test automation. I lead a team of five junior developers working across session lifecycle, fault recovery, real-time streaming, and the device-control protocol.

I designed and built the original device-control abstraction layer used by platform tests, and led the extraction of a core service from the monolith into a standalone Spring Boot microservice. The change reduced deploys from about an hour to about 20 minutes.

I engineered session recovery for transient and harder failures, and built a real-time stream-health monitor that catches more than 80 silent session freezes per week. I also rewrote crash detection, eliminating over 90% of false-positive crash reports.

Earlier, I built Java back-end services and REST API integrations at PAKSOFT Global (Pvt) Limited. At FinPocket Trade (Pakistan Stock Exchange), I shipped Kotlin and Retrofit REST integrations and an in-app review flow for a fintech application.
