About
The bridge between technology, product and business.
I'm Mateusz — a fractional CTO and technology advisor. I spent over a decade building SaaS products, most recently as technical co-founder and CTO of PushPushGo, a platform processing more than 1.5 billion events a day.
Today I bring that experience to founders and product teams who need senior technology leadership — without hiring a full-time CTO. I sit between technology, product and business, translating technical trade-offs into decisions that move the company forward.

Philosophy
Technology is not the goal. Business outcomes are.
Good architecture is invisible. It exists so you can ship faster, de-risk decisions and grow without being held back by your own codebase.
Faster product development
Architecture that keeps delivery speed high as teams and features grow.
Lower technical risk
Early visibility of what can break — and what it would cost if it did.
Better decisions
Technology trade-offs framed as business trade-offs, in language founders understand.
Scalable growth
Infrastructure, teams and processes that handle the next order of magnitude.

Your project here
I help founders take products from idea to scale. This space could be your story.
Security & Compliance
Leadership that covers governance too.
Security and compliance are part of CTO-level technology leadership — not a standalone consulting service. I help companies prepare for audits and regulatory expectations the same way I help them architect for scale: pragmatically, with the business in mind.
Whether you're facing investor questions, a DORA or NIS2 timeline, or simply want a stronger security posture, the work is an extension of good engineering leadership.
- DORA readiness
- NIS2 technology risk considerations
- ISO 27001 security practices
- Security audits and vulnerability management
