I design PCBs and write firmware for the layer between silicon and software — bare-metal C/C++ on microcontrollers, FPGA development, and RF / SDR systems.
- 🔧 ~6 years of microcontroller firmware · ~4 years of PCB design
- 🛰️ Daily work spans embedded firmware, FPGA / HDL, and RF / SDR
- 🧪 I enjoy taking a board from schematic → layout → manufacturing → bring-up
- 📻 Class-B amateur radio operator — callsign TB2REV
- 🌍 Based in Ankara, Turkey · open to remote / contract embedded work

Active on the air as TB2REV (Class B). I'm drawn to HF/VHF digital modes, building SDR front-ends, designing antennas, and doing DSP for signal processing. When I work on RF projects here, it's usually an MCU or FPGA paired with an RF chain — always happy to swap feedback and ideas with the ham/SDR community.
