I'm a software engineer. I build products end to end and ship them fast, with AI as part of how I work every day.
Six years building B2B SaaS at international companies, with acquisition experience along the way. AI-assisted development is my daily workflow, not a novelty.
22 AI models, one ball. Open source.
A live 3D football match where each of the 22 players is its own AI model call. Every touch is a typed multiple-choice question and the model answers with probabilities. Watch all 22 decide, or press J and take over the number 9.

Livestock equipment manufacturer. Live in three languages.
Geppas makes livestock and veterinary equipment in Konya, Türkiye, and exports to 18 countries. As their technical partner I built and shipped their new website in Turkish, English and Russian, with a full product catalog, 3D product views and quote requests, and I keep working on the internal systems behind the business.

The companies I've worked with, and what I did there.

The first thingcustomers see.
Frontend Developer
2020–2021 · San Francisco, USA
Front serves 200M+ customers and raised $138M. Developed the company landing page with a team of five engineers, with high SEO and accessibility scores.
It is the default workflow, not a novelty. Design, implementation, tests and docs all go through AI tooling, which changes what one engineer can realistically own and how fast it ships.
That is the normal case. I am comfortable with ambiguous scope and short delivery cycles, and I take a fuzzy requirement through to a release.
No. I work directly with product and clients, the people who actually need the thing, rather than receiving specs through a chain.
Remote and async by default: written updates, clear handoffs, and progress you can see without a meeting.
Available for contract work. Send a few lines about the problem and I'll reply with how I'd approach it and when I could start.
