Hi, I’m Dharun (VU3BZY), an embedded software engineer focused on trustworthy firmware and hardware security. I build and harden drivers and protocols for ARM Cortex-M systems, explore Zephyr RTOS, and prototype on FPGAs to understand failure modes before they ship.

I maintain open-source tooling and research notes—RF experiments, hardware security writeups, and reproducible build guides—so others can learn faster and reproduce results. Notable project: audio-ninja, a USB HID keystroke bridge whose motto is “portable control, zero fuss,” originally built to repurpose old speakers into a simple surround setup for quick demos and lab rigs. I care about transparent, repeatable workflows: clear build steps, CI that actually exercises edge cases, and documentation that turns hardware quirks into reusable patterns.

How sponsorship helps

• Funds dev boards, analyzers, and radio gear to keep testing honest
• Covers cloud time for CI so builds stay reproducible
• Buys focused hours for mentoring newcomers and writing better docs

If you care about resilient firmware and open hardware, your support directly keeps these projects moving and accessible to everyone.
