What I'm looking for

I'm looking to build high-impact web or mobile products where I can own frontend architecture, improve performance and user journeys, and collaborate closely with product and engineering teams.

I'm building Forte Travel at Fortebank, owning the parent shell and a railway-service microfrontend in a four-app architecture. I built the desktop trips.fortebank.com experience and internal admin panel from scratch, improving Lighthouse scores from 50 to 85.

I've improved conversion through Amplitude funnel analysis, connected web and native analytics through a JavaScript Bridge, and delivered SSR, React Native, real-time, and performance-focused products across Datafy, Salesautomators, Restoration AI, and AML Academy.
