I design systems that move — from urban traffic flows to interactive frontends. Co-creator of Tripvice.net, an AI travel planner.
Two careers, one obsession
I started modeling intersections and watching cities breathe. Then I realized frontends are traffic systems too: route attention, smooth congestion, optimize latency. I've been building them ever since.
I'm a Road & Transport Engineer who fell in love with web frontends somewhere between modeling a signalized intersection in Vissim and trying to make a React form not feel like one.
Today I split my time between freelance frontend work and side projects. The most consequential of those is Tripvice.net — an AI travel planner I co-created. I built the frontend, the itinerary canvas, and the streaming response UI.
I'm fluent in both vocabularies: signal timing diagrams and React DevTools, microsimulation models and design systems. That overlap is rarer than it should be, and it shapes how I build.
Built for both worlds
Self-assessed on a /100 scale. The radar is the frontend stack I use day-to-day; the bars are the engineering side.

A flagship and two learning vehicles. Hover to peek; click to expand.
Topic-clustered news reader with saved-for-later, keyboard nav and a focus-mode reader view.
The dice game, rebuilt in vanilla JS as a learning vehicle for state machines and DOM patterns.
From signal timing to streaming UIs
Five years across two disciplines. The throughline: making complex systems legible.
