At Tamara, I lead the Remittance team building international transfers from Saudi Arabia for supported nationalities. I own PRDs, RFCs and ERDs, while staying hands-on with architecture decisions and code reviews.

At Tamara, I led the end-to-end Flutter migration of core app modules and built the Current Account module on a live BNPL platform. Earlier, at Xoxoday, I led the Empuls native-to-Flutter migration, which improved load time by 8% and shortened release time by 20%.

Across mobile work in fintech, banking, media and health, the apps I’ve built or led reach 5M+ users. At Jio, I cut video-call latency by 40% through changes to media resource handling.
