Available for freelance & full-time

I build the whole system — and I keep it running.

Full-stack developer and automation engineer in Budapest. I ship complete products solo — frontend, backend, payments and the self-hosted infrastructure underneath — built on a science and quantitative-trading background.

Smart Trader

Started as a PineScript strategy on TradingView and grew into a fully automated, self-optimizing Python system running on my VPS — it tunes its own parameters, executes, and publishes live signals to a public Telegram channel and Instagram. I built the platform end to end, including the smartraderbot.com site.

The stack I run

Everything self-
hosted, always on.

One Windows VPS runs the lot — every service registered under NSSM, sitting behind a single Caddy reverse proxy with TLS. It's production, and it's mine to keep alive.

The path

From geophysics to
full-stack, over 15 years.
