🤩
RockstarKarol Kokoszka is a software engineer with three years of recent professional experience and a background stretching back to senior development roles since 2013. He has moved between embedded and infrastructure-focused positions—from longtime engineering work at Fibar Group and ADB to a DevOps role at Liberty Global and now software engineering at Parity Technologies—bringing a practical mix of firmware, systems and cloud tooling experience. Based in Lubusz Voivodeship, Poland, he augments his formal computer science training from Uniwersytet Zielonogórski with ongoing blockchain-focused studies at the Polkadot Blockchain Academy. Karol’s career shows a pattern of transitioning from device-level engineering to networked and decentralized systems, indicating strong adaptability and a taste for complex, multi-layered problems. Colleagues can expect an engineer comfortable bridging development and operations who pursues new domains (like Polkadot) to stay ahead of architectural and tooling trends.
