Design Engineer Experiences
I build digital products where cortex meets artificial — from the first sketch to the last deploy. Interfaces with a pulse, architectures that scale, code that ships.

Product & UI/UX Design
Research, flows, wireframes, high-fidelity interfaces and prototypes that answer questions before development asks them.
↗ /02Software Architecture
Domain-driven services, event streams, clean contracts. Systems designed to survive their fifth year, not just their first demo.
↗ /03Full-Stack Engineering
TypeScript end to end — performant frontends, resilient APIs, infrastructure as code and pipelines that ship on green.
↗ /04Motion & Interaction
GSAP choreography, WebGL scenes and micro-interactions — the difference between an interface and an experience.

03 — About
Cortex,
Cortex,
meet artificial
I'm Felix — a hybrid of designer and engineer based in Cologne. For over a decade I've moved between pixels and processes: sketching interfaces in the morning, designing the systems behind them in the afternoon, and writing the code that binds both at night.
Cortificial is that practice condensed into one word — the human cortex and the artificial machine, working as one loop. No hand-offs, no translation loss. The person who designs the button also decides how its click travels through the stack.
