About Aaron

I’m Aaron Qian, a software engineering consultant, hardware hobbyist, and father. I learned to program young, built my first C++/DirectX game in high school, and studied Computer Engineering to understand both the hardware and the software that drives it. For the past 20 years I’ve partnered with founders and small teams to turn messy ideas into stable systems.

How I work: Begin with goals and values, translate them into minimal requirements, choose the simplest architecture for today only. I keep code maintainable so iteration keeps cheap. Ship early, measure real signals, and refactor with intent, and let progress compound.

I favor architectures that are boring in the best way: fast, observable, and easy to reason about. A system is “done” not when there’s nothing left to add, but when there’s nothing left to remove. I contribute to open source and occasionally upstream fixes (including bugfixes to Ruby) because open source matters. Most of my attention right now goes to OpenServoCore — an open hardware project to turn cheap MG90S servos into smart actuators with cascade control and a DYNAMIXEL-style Rust firmware, lowering the barrier to robotics for students and hobbyists.

If that mix of craft, clarity, and curiosity resonates, welcome.
