About
THE GUY WHO
ACTUALLY SHIPS
I'm Saurav Kumar — a full-stack engineer and architect from Gurgaon, India, with an Electronics & Communication degree from NIT Sikkim and an unusual range: I'm equally at home in a Flutter codebase, a NestJS backend, and an STM32 datasheet.
That range isn't trivia — it's how a 300,000-line transport SaaS gets built by one person, how a phone ends up flashing microcontrollers on a factory floor, and how your project avoids the three-specialists-and-a-project-manager overhead.
I run CraftsmenLab — a small studio for industrial embedded and web/app work — and I've delivered for logistics, mobility, e-commerce, manufacturing and construction clients.

The hardware background is why the embedded work is real — signals, protocols and datasheets were the degree, not a weekend hobby.
