What I'm looking for

I’m looking for a role where I can work on full stack architecture and cloud-native delivery, ship AI features with measurable impact, and mentor teams—while owning quality via testing, performance, and production monitoring.

I’m a Senior Software Engineer and Technical Lead with 7+ years building high-performance, scalable web applications that serve 2M+ users. I’m known for delivering business-critical AI features using OpenAI GPT-4 APIs—reducing customer support tickets by 35% and improving first-response resolution by 45%.

I lead end-to-end frontend architecture (React.js, Next.js, TypeScript, micro-frontends, design systems) and production excellence across monitoring, testing, and cloud-native delivery. Across roles in Dubai and Abu Dhabi, I’ve improved Core Web Vitals by 60%, optimized API response times from 3.2s to 800ms, and guided platform modernization—such as OpenShift to AWS EKS migration—cutting infrastructure costs by 25% while improving deployment efficiency.
