Started in chemistry. Ended up in a factory, reorganizing production lines in 3D because it was faster than drawing on paper. Quit that job. Built tools. Still going. Based in Szeged, Hungary. Available for the right project.
What I do
Cinema 4D, Blender, the Adobe suite. Product visualization, advertising, motion. If it needs to look good in a render and actually match a brief, this is the lane. I've been doing it long enough that I'm fast, and picky enough that the results are good.

A semi-automated system for generating patient-specific, 3D-printed orthopedic walking casts from 3D body scans. Breathable. Washable. Adjustable. Printable in a living room. Designed to replace a 150-year-old technology — the plaster cast — with something that doesn't turn a recovery into a punishment.
The walking cast
The cast snaps on with magnets and two wide velcro straps — one around the calf, one threaded through the outsole. As your calf shrinks during recovery, the straps adjust. The outsole has a structural void in the centre that collapses when you stand, giving a flatter contact surface, but rolls forward on each step so you can walk without needing ankle flexion. Held by magnets and physics.
The insole
Every walking cast needs an orthopedic insole. So I built one. Infill pattern and density are tuned per person — foot shape, arch type, body weight — soft where comfort matters and firm where support does. Thin enough to fit inside most shoes. It comes with the cast. It's not an afterthought.
The method exists. The code exists. The printers exist. What doesn't exist yet is the funding and the regulatory infrastructure to manufacture it at scale. This one is a long game, and I'm still playing it.
See it on Instagram →FDM printing service for prototypes, custom parts, and physical goods. I run the machines, tune the profiles, and ship the results. OrcaSlicer, real hardware, actual tolerances. The full workshop lives at FORGE.
Skills
I'm wired to go 110% on things that interest me, or not at all. That's led to an unusually wide range. For a freelancer, that's the point.

How we got here
Studied chemistry at the University of Szeged. Got very good at thinking in systems, tolerances, and why things fail.
Taught myself Java at Flow Academy. Discovered that code is just chemistry with fewer explosions and more semicolons.
Worked as a factory technologist — product development, pipeline design, quality systems. Started using Cinema 4D to reorganize production floor layouts in 3D because it was faster than drawing on paper. Got good at it.
The company's IT lead quit mid-project. The ERP system had no one driving it. Someone noticed I could code. I went from developing products alone to leading the full ERP rollout across the factory — warehouse, production, quality lifecycle. Wrote the SQL, built the integrations, kept going until the handover was clean. Junior developer. Senior problem.
Broke a leg. Spent a summer in a plaster cast. Thought: there has to be a better version of this. Started sketching what became CAST.
Founded 3PO. Built CHRONOS — a scene variation management plugin for Cinema 4D that I wanted to exist and didn't. Shipped it. Still improving it. Working on what comes next.
