Senior Avionics Software Design Engineer · DO-178C DAL A · Systems Engineering
Ankara, Türkiye · "Ancora imparo" — still learning
I build safety-critical avionics software — the kind that has to work every single time. My work spans the whole DO-178C lifecycle: requirements, design, code, verification, and the plans and standards that hold them together.
- 🛩️ Now: Senior Avionics Software Design Engineer at ESEN System, developing DO-178C DAL A software for VOR/ILS navigation receivers (C99 · MISRA C · Xilinx Zynq · ARINC 429 · MIL-STD-1553).
- 🧪 Building test automation infrastructure and internal tooling: a TQL-5 qualified tool, Qt/C++ and Python utilities, Jenkins quality gates, Grafana/Prometheus metrics, and an AI-assisted VS Code extension for test scripts.
- 🎓 MSc in Computer Software Engineering (Hacettepe University) · BSc in Electrical & Electronics Engineering (IzTech) · now pursuing a second master's in Systems Engineering.
- 📜 INCOSE CSEP · ISTQB CTAL-TAE · ISTQB CTFL
- 📖 Writing an open, community-driven Turkish book on avionics software at aviyonikyazilim.com.
- 🌍 Wikimedia technical volunteer since 2014 (225k+ edits) and co-founder of Dijital Bilgi Derneği.
- 💬 Ask me about DO-178C, requirements engineering, MISRA C, test automation or systems engineering. Happy to help!
