Climate and energy software
Dynamic tariffs, EMS, VPP, demand-side flexibility, balancing markets.
Fractional CTO / Technical advisor / Warsaw
I help climate, energy, and AI founders ship hard technical products without hiring a full senior team yet.
CTO at Pstryk, where I built the platform behind Poland's first dynamic electricity tariff. 17+ years across IoT, energy markets, AI, and high-throughput backend. Currently taking a small number of fractional CTO, technical advisor, and due-diligence engagements.
Where I'm useful
IoT at scale
MQTT fleets, edge/cloud architecture, time-series at high throughput.
Building with AI
LLM integration, computer vision, agentic workflows in production.
Engineering leadership
Team building, architecture review, technical due diligence for VCs.
