Open to remote roles & fractional work

Krishna Yadav
The Product Builder

A full-stack engineer who takes ideas from the first line of code to a production deploy. I handle frontend, backend and infrastructure myself, so nothing gets lost in a hand-off. Two years shipping real products for founders and teams across the US and Europe.

About

The person behind the pull requests

I'm a product-focused full-stack engineer who owns features from architecture through to production: UI, backend systems, REST & GraphQL APIs, database design, and deployment. I don't hand work off, I ship it.

Currently a Full-Stack Engineer at GBCSGroup (SKYIT), on a fully remote, Canada-based team. Alongside that, I run a one-person freelance practice delivering production systems for e-commerce and SaaS clients, so "the developer" and "the person who talks to the client" are usually the same person.

My stack is TypeScript-first by default: strict compiler settings, runtime validation with Zod, and code the next engineer will actually enjoy reading. I use AI-assisted tooling daily to move faster without cutting corners.

Based in India, working remotely and comfortably across US and EU time zones.
