Currently

As Head of Engineering at Oaasis — a €4.9M-funded startup — I've taken the company from 0 to 1: building the engineering team, the technical foundations, and the product itself in one of the hardest domains there is, supply chain planning. I lead 5 individual pods, own the engineering department end to end, and keep delivery fast, the team motivated, and every release tied to real business value.

We've made the product the go-to supply chain planning solution for €30–60M-revenue consumer goods companies. I built an AI software factory and keep us on the frontier of AI tooling in our day-to-day workflow, and I stay hands-on across the full stack — a NestJS API, a React design system, and Rust services for optimization, forecasting, and data ingestion — as the platform's most prolific contributor with over 1,300 commits.

What I've built

• Took Oaasis from 0 to 1 — building the engineering team, technical foundations, and product as Head of Engineering at a €4.9M-funded startup.
• Built the go-to supply chain planning solution for the core segment: consumer goods companies in the €30–60M revenue range.
• Built an AI software factory.
• Shipped a production-grade product in a genuinely complex domain — supply chain optimization, forecasting, inventory, and constrained allocation.
• Lead and set direction for 5 individual pods, driving high delivery, an AI-first workflow, team morale, and business value.
• Hands-on across the full TypeScript + Rust stack as the codebase's top contributor (1,300+ commits).

Track record

• Santander Nordic — Designed quality processes that cut release cycles from 4 months to 6 weeks; built test-automation foundations across 6 teams (28 engineers).
• Swoop Funding — Scaled the platform from 0 to 50k+ businesses, led the monolith → microservices and multi-tenant migration that secured a £5M grant.
• Staff Bit — Co-founded and led as CTO to a successful exit; ran enterprise transformations for clients including Santander and Zara.
• Euvic — Built architecture serving 2M daily users at 99.9% availability and opened a new subsidiary.

How I think

I'm a systems thinker who's relentlessly business-value-oriented. Technical complexity isn't a selling point — ROI, leverage and reliability are. I favour right-sized solutions over both over-engineering and fragility, and I believe quality is a team effort, not a gate at the end.

I created P.I.R.A.T.E.S., a framework for evaluating and advancing quality maturity in engineering organisations, and I facilitate CTO mastermind sessions — because the top is lonely, and the right peer conversation changes decisions.

Personal projects

• Personal CFO — A personal-finance platform: transactions, net-worth tracking, FIRE forecasting, Monte Carlo scenarios, and a bear-market stress test.
• Jemik — A weekly meal planner for families with a Thermomix: builds the whole week from Cookidoo recipes around your family's tastes and allergies, with portions sized to hit daily goals.
• Golf RPG — A golf game with RPG progression, built in Godot.

Stack

TypeScript / NestJS, React, Rust, C#/.NET, Python, Azure, AWS — and AI agents and automation wherever they create real leverage.

Beyond work

Based in Poland, married with two small kids — family comes first. Outside of that: golf, board games, Dungeons & Dragons, and writing about engineering, leadership and living deliberately on my newsletter.
