🛠️ About me

• 🌍 Based in Poland and Sydney Australia at the moment 🦘 (& more often than not on the road)
• 💼 Building 5G NR L1 (C/C++ sometimes AVX and other DSPs) with custom ASICs at Tietoevry
• 🕹️ Co-running Sticky Piston Studios – recent titles: The Deluge (HackYeah 2022 winner), Tiny Trucks (Slavic Game Jam 2025)
• 📝 I blog about embedded programming, hardware hacking, and optimization tips (and travelling!)

✨ Highlights

• Slavic Game Jam 2025 - Developing PillEngine - adding networking and physics support to create a game about Tiny Trucks
• Hackaday Supercon 2025 - Lightning talk on hacking around IceBreaker FPGAs
• Embedded OSS Summit 2024 NA – ZLED frame using Zephyr talk
• FOSDEM 2024 – Open RAN & Intel FlexRAN talk
• Hackaday Supercon 2023 – ML blood-pressure inference on EOS S3 on Zephyr
• Embedded OSS Summit 2023 – Same as above :grin:
• State of Open Con 2023 – FPGA-accelerated tcpdump for embedded Linux
• HackYeah 2022 – 🏆 The Deluge won overall competition
• GSoC 2021 @ beagleboard.org – GPGPU lib for BeagleBone Black
