What I'm looking for

I'm looking to lead high-impact mobile engineering for FinTech or trading products, building secure, high-performance Flutter and native experiences while shaping architecture, delivery systems, AI capabilities, and developer growth.

I've led mobile engineering for Abyan Capital's trading and robo-advisory platforms, helping scale bilingual, CMA-compliant products to 1M+ users and SAR 3B+ trading volume.

At Abyan Trading, I architected cross-platform features across Flutter, Kotlin, and Swift, including options, IPOs, social trading, portfolios, watchlists, and native payment integrations. I also built a five-WebSocket pricing infrastructure with sub-second failover and improved crash-free performance from 88% to 98%.

I've delivered production AI capabilities including an interactive assistant and an on-device Gemma/LiteRT news-summarization engine. By adopting Shorebird OTA releases, I reduced hotfix deployment time from 48 hours to 15 minutes.

Earlier, I built production Flutter apps at Clustox and SPS, including the offline-first Azal.io workforce app. I enjoy establishing clean architecture, stronger release processes, and mentoring teams as they grow.
