Engineering Excellence meets AI Innovation
With over 15 years of experience in Big Tech, I build high-scale products that bridge the gap between complex engineering and the AI-first future. I lead teams, architect systems, and ensure quality remains the foundation of every innovation.
AI Product Engineering
Beyond simple prompts — I build real-world AI products. From multi-agent workflows to custom local model integrations, I architect solutions that solve complex problems.
Strategic Team Lead
Managing engineering efforts for browser extensions used by 100M+ people. I focus on mentoring, optimizing workflows, and delivering high-impact features.
Quality at Scale
Over a decade of experience in test automation and quality systems. I build resilient, performant systems where security and stability are core features, not afterthoughts.
Knowledge Architect
I translate complex technical shifts into clear strategies. From international conferences to local workshops, I teach how to move from spectator to AI-powered architect.
Beyond the Surface: My AI Journey
I don't just use models in my daily coding -- I understand their DNA.
Deep Technical Knowledge
Transformers, tokenization, embeddings. I understand how attention mechanisms shape intelligence.
Effective model usage
I know how to work with models for maximum effectiveness. I build chain of agents that collaborate to achieve better results.
Local Models
Running models locally. Working with vision models (VLM), speech synthesis (XTTS), image generation (Flux.1).
Security & Privacy
I know which data can go to the cloud and which must stay local. I configure AI environments with privacy and compliance in mind.
Building with AI
Production-grade side projects — full-stack, AI-native, open to explore.
Kryształ AI — AI-generated local news digest
A daily newsletter for the Podhale region (southern Poland), generated end-to-end by an AI agent pipeline — scraping, deduplication, summarization via Gemini, and delivery via SMTP. Built with Node.js, Firebase, and React. Free and open to all readers.
JotBook
Browser extension (MV3) + PWA + Node.js backend. Detects book metadata via Schema.org and Open Graph, syncs to Firestore. Supports Empik, Amazon, Lubimyczytać, Bonito. 268 tests passing.

I built my first computer at age 10 and created my first website at 15. For over 15 years, I have been professionally navigating the IT landscape, evolving from a curious tinkerer to a strategic leader. I work independently, taking full initiative to deliver innovative solutions that bridge the gap between complex engineering and real-world needs.
Currently, as a Senior JS Developer at eyeo (AdBlock Plus), I work on browser extensions used by over 100 million people worldwide. My focus on privacy solutions and high-scale performance requires a deep understanding of the modern web ecosystem and the responsibility of building for a global audience.
In the realm of Artificial Intelligence, I am a practitioner first. I’ve developed custom solutions including a local TTS-based audiobook creator and a fully automated AI-generated newsletter. I use Claude and advanced LLM workflows daily, not just to build software, but to refine the very process of development and teach others how to master these tools.
I believe technology is only as valuable as our ability to share it. I train IT companies, run workshops for seniors at the University of the Third Age, and teach programming to youth in foster care through the Hakersi project. Whether I'm presenting at international conferences or teaching cybersecurity in schools, my unique strength lies in translating complex technology into human language for every age group.
