Currently: building voice agents & interactive systems

Leon — Computer Science student at ETH Zürich crafting voice agents, web tools, and systems with a playful edge.

I blend GameDev instincts with WebDev speed to prototype AI assistants, dashboards, and interactive experiences. Curious about physics, precision about latency.

What I do

Systems thinking, playful polish.

WebDev

Fast frontends with clean data flow, dashboards that stay readable.

AI / Agents

Voice + text agents with real tools, latency-aware pipelines.

GameDev

Interaction systems, input feel, small shaders, telemetry loops.

Systems / Tools

APIs, queues, observability, glue code that stays boring.
