At Experion Technologies, I lead frontend delivery for a fintech product, building payment flows with Stripe and Apple Pay, AI customer support integration through Fin AI, and real-time data synchronization with Socket.IO.

I own frontend architecture end to end: component patterns, API design, code reviews, documentation, and delivery estimates. I mentor four engineers and build dependable critical-path experiences with Jest coverage for authentication and payments.

I rebuilt a map-based search across roughly 4,000 listings using progressive batched loading, client-side caching, and server-side geocaching to remove load-time jank. I’ve also delivered multilingual, right-to-left support in English, Spanish, and Arabic.

Over seven years at Experion, I’ve grown from trainee to lead while building reusable design-system components, accessible WCAG-aligned interfaces, and high-performance React applications. Outside work, I build full-stack products including an online course platform and a real-time Firebase expense tracker.
