Full-Stack Developer & AI Engineer

Building intelligent systems at the intersection of software engineering and artificial intelligence. From React frontends to multi-agent AI architectures — I ship things that work.

From electronics in Slovakia
to AI systems in production

I started with electronics in Slovakia, moved to Ireland, and taught myself to code through Code Institute. Those early days were all about fundamentals — Django e-commerce stores, React portfolios, Flask CRUD apps.

Then I joined a small startup that would become Talentiqa.ai. What started as frontend Angular work evolved into building the full stack — and eventually architecting multi-agent AI systems with LangChain that process thousands of candidate interviews.

In parallel, I'm building my own AI infrastructure — autonomous Telegram agents on self-hosted servers, local LLM routing with Ollama, and real-time monitoring dashboards. Every project has a live URL. I ship things that work.

What sets me apart

01

Full-Stack + AI

Rare combination of traditional web dev skills with deep AI/LLM engineering experience. Not choosing between frontend or AI — doing both.

02

Production AI Systems

Not just playing with APIs. Building multi-agent architectures, RAG pipelines, and voice AI in production that processes thousands of interviews.

03

Self-Hosted Infrastructure

Runs own server with Docker, Traefik, Ollama, and autonomous agents. Understands infra from the metal up.

04

Startup Mentality

Working in a 9-person funded startup. Wears multiple hats, ships fast, iterates faster. Built for chaos.

05

Trilingual

Native Slovak, fluent English, fluent Czech. Works across CZ/SK/IE markets and teams without friction.

06

Builder

Ships things that work. Portfolio, study platform, monitoring dashboard, Telegram bot — all live and running. No vapourware.
