Creator of n8n-mcp — the open-source tool AI agents use to build n8n automations. 108,000+ engineers, 22,000+ GitHub stars, used by teams at Deutsche Telekom, PayPal, Intercom, MIT and NYU.
I build production AI systems for companies. Not slide decks, not demos that stall after the pilot. Systems that run in production and stay maintained: 750+ workflows delivered across multiple companies in 5 industries. I work directly with the people who do the work, so the system that ships is one they already use.
What I build:
How I work: fixed price for setup, monthly retainer for maintenance and new automations. You buy outcomes, not hours.
Industries served: e-commerce, legal & tax, professional services, healthcare, digital advertising. Previously Head of AI at Boldare and current IT/AI advisor to the World Bank Group.

Working with Romek has been a very smooth and professional experience. He has a strong understanding of business needs, proposes practical solutions, and explains complex technical topics clearly. Throughout the entire project, we could rely on excellent communication, timely delivery, and responsive support. I recommend Romek to anyone looking for a reliable and committed partner in automation and n8n-based solutions.

We have been working with Romuald and AIAdvisors since January 2025 and continue to do so. He combines strong n8n, AI, integration and scraping skills with a practical, iterative approach. He turns complex ideas into simple first experiments, delivers reliably and actively transfers knowledge to our team. Thanks to this cooperation, automation and AI are becoming real internal capabilities at ESTYL.
The technical partner who changed how I run my company
Adrian G. · mTeam Group ·
As a CEO, I've worked with plenty of technical vendors — Romuald is the one who moved the needle. He set up and maintains our n8n platform (queue mode, upgrades, rock-solid), built our Amazon scraping workflows and Supabase backend, then mentored me on using Claude Code to run the business — which genuinely changed how I work. He explains everything in plain language, so you're never in the dark. If you want automation that lasts and a partner who levels up your team, hire him.
