▸ General Description

Embedded firmware engineer who likes to understand systems down to the register. I spent 3+ years at Qualcomm debugging and shipping production C firmware deep inside ARM-based LTE / 5G modems — the kind of work where a logic analyzer and a clean stack trace are your best friends. These days I build my own embedded systems end-to-end on STM32 and Linux — RTOS, drivers, bootloaders, CAN and BLE — and I treat the write-up (architecture, debugging notes, a validation plan) as part of the deliverable, not an afterthought.

▸ Functional Blocks

C C++ STM32 FreeRTOS Linux ARM Bluetooth Python

▸ Featured Builds

▸ Operating Conditions (currently)

  • 🟢 Building — deeper Linux driver work (char devices, sysfs, driver model)
  • 🟢 Building — AI-assisted embedded workflows (harnesses, test plans, docs)
  • 🔵 Exploring — TinyML on microcontrollers (quantization, on-device inference)
  • 🟡 Planning — OTA updates & rollback (A/B partitions)
  • 🟣 Learning — embedded Rust for safer firmware
