I'm an embedded software engineer and mechanical design engineer working in robotics — I write the firmware and control systems, and design the mechanical hardware that runs them.

Founder & CTO of URO Bangladesh, and the founder of two ventures — Darains.dev (B2B embedded software) and 3D Printify BD (3D printing & design). I've led control software and captained competition robotics teams from build to the field.
