What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I’m a frontend engineer with 6+ years of experience building scalable, high-performance web applications using React and TypeScript. Most recently at Deel, I worked on global, high-impact workflows in a distributed environment, contributing to products used by thousands of businesses worldwide.

Prior to that, I built real-time systems and financial platforms, including trading and auction interfaces supporting 100K+ users with WebSockets. I’ve worked on performance optimization, authentication (including passkeys), push notifications, and internal tools that improved team efficiency.

I enjoy going beyond UI — understanding the full product, data flow, and system design to build reliable, user-focused experiences. Lately, I’ve been exploring AI-powered interfaces and how they can enhance modern web applications.
