Summary
🤩
RockstarJacek Ziółkowski is a Python developer with 11 years of professional experience, currently working at STX Next and living in Greater Poland Voivodeship, Poland. He brings a practical blend of software and operations expertise from a long tenure as an IT specialist and DevOps-minded Python developer at a family-run printing business where he also supported in-house CRM/ERP systems and production management. Jacek is an active embedded/IoT contributor in notable open-source projects like Tasmota and Tasmotizer, where he implemented support for 74x595 shift registers and adapted flashing/UI logic for ESP8266/ESP32 tools. That hands-on firmware and tooling work shows he’s comfortable across low-level embedded code, hardware integration and higher-level Python tooling. Colleagues would describe him as a pragmatic problem-solver who moves between device firmware, utilities and web-oriented Python development.

Contributions summary:Jacek contributed to the `tasmota` firmware, primarily focusing on adding support for 74x595 shift registers. This included implementing the necessary code for controlling the shift registers, integrating them with the existing system, and providing configuration options. The changes involved modifying existing files and creating new ones to incorporate the shift register functionality. The user also made minor improvements to existing code like in the LVGL portion of the firmware.
