I completed the AI_devs3 ↗ advanced AI development program and learned how to build custom AI agents, advanced prompt engineering, multimodal processing, RAG implementation, and integrating with leading LLM providers.

Full-time co-founder role remotely in Poland. Model Guide ↗

Model Guide was an AI assistant for Beauty & Skincare e-commerce, helping customers create personalized product regimens. As founding engineer, I built our proof-of-concept and led customer validation calls.

Key technical contributions:

• Built client-side SDK with secure iframe communication
• Developed internal testing Playground using customer data

I left the project after determining through founder-led sales calls that market demand was insufficient.

Tech stack: TypeScript, Python, React, Remix, Tailwind CSS, Chrome Extension API

Freelance, remote in Poland.

I worked as an independent consultant, advising both startups and established companies.

I conducted technical and product audits for investors evaluating startups, and helped a major logistics company (2000+ employees) transition to a product operating model.

I also served as one of the lead lecturers for Product dots ↗, a specialized product management course for founders in Poland.

After a decade of startup intensity, I took a deliberate pause to recharge and recalibrate.

I invested this time in both personal growth and exploration: fell in love with road cycling, deepened my photography skills, traveled, and explored technical subjects that had always interested me: technical analysis, No-Code and AI.

While serving as CPO at Packhelp, I completed Andrzej Santorski's year-long leadership program at Warsaw University of Technology Business School.

Full-time in Paris, Les Petites Tables ↗

As technical co-founder of this French restaurant discovery platform, I developed key features and pitched to investors, helping secure our acceptance into NUMA, a prestigious Parisian startup accelerator.

Full-time in London, OpenAsset ↗

My first professional software development role, where I learned how to code and how to deliver high quality, reliable software.

After my first year, I led OpenAsset's transformation from feature-driven to design-driven development. While continuing my engineering work, I took on the additional role of UX Lead, running workshops with enterprise clients like Foster + Partners, designing features, and implementing them myself.

We were early adopters of React in production. I immersed myself in London's tech community, attending meetups and dedicating evenings to improving my programming skills to match more experienced colleagues.

Tech stack: JavaScript, Perl, Require.js, React, Angular, Backbone/Marionette, Node.js

Full-time in London, building my first startup while studying at university.

We created a social platform connecting young creative talent with agencies and job opportunities. I built our web platform and managed our media production team, organizing film festivals and artistic events to promote our community.

Though the startup ultimately didn't succeed due to our inexperience and divergent visions, it provided invaluable lessons in product development, technical implementation, and team dynamics.

Tech stack: Node.js, MongoDB, JavaScript

It was during that time when I discovered my genuine passion for programming and computer science. I found myself losing track of time coding, learning languages and concepts on my own well beyond coursework requirements. This period defined my career path and gave me the skills to start building real products.

Prior education: BA in Media & Communications from Goldsmiths, University of London (2008-2011)
