👤
SeniorMatt Kozak is a founder and hands-on technology leader with 13 years of professional experience and nearly two decades of engineering practice, currently driving Pstryk’s dynamic tariff platform as CTO while launching Codeboards. He blends cloud-native and on-prem AI work—building LLM-powered solutions and production pipelines across Python, Go, and Ruby—plus deep IoT and LoRaWAN expertise for smart-city and green-tech projects.

A practical polymath, he pairs system-level architecture with hands-on coding and hardware networking, often applying open-source models and vector DBs in production AI stacks.
