Hey!
I'm Ajay.

About

Hardware fascinates me, especially in unusual target environments.

I'm privileged to have designed and engineered systems that operate in many contexts, including inside the human body, 30,000 feet in the air, and across millions of phones, computers, and servers.

The perfect pairing of software and hardware is bliss.

+ Design Philosophy & Working Style

Design Philosophy:

Stack Preference:

Working Style: Look around corners. Pre-empt pain. Comfortable in labs and with hardware. Value clear documentation and thoughtful code review.

Currently working on:

  • Making devices and prototyping on my CNC machine
