Jakub Duchniewicz

Embedded systems engineer • low-level software • Linux / seL4 / 5G / FPGA • Co-founder @ Sticky Piston Studios

🌍 Based in Poland and Sydney Australia 🦘 (& more often than not on the road)
💼 Embedded systems engineer working across low-level software, hardware/software integration, performance work, and bring-up
📡 Background in 5G/LTE, Linux, seL4, FPGA- and ASIC-adjacent systems, protocol-layer software, and cross-layer debugging
🕹️ Co-running Sticky Piston Studios – recent titles: The Deluge (HackYeah 2022 winner), Tiny Trucks (Slavic Game Jam 2025)
📝 I write about embedded programming, hardware hacking, optimization, and the occasional travel or side-project story

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 😁
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

microkernels • ARM/RISC-V/x86 architectural quirks • ELF-hacking • side-channel hardening • reverse engineering odd IoT gadgets
