Harsh Vashistha

I build digital products that people actually want to use.

Over the past 4 years, I've gone from crafting UI components at OYO to co-founding SwitchZy—an AI job matching platform that's helping hundreds of users find their dream roles. Along the way, I've learned that great software isn't just about clean code; it's about solving real problems elegantly.

My journey:

->Currently building SwitchZy from scratch—handling everything from FastAPI backends to Next.js frontends to DevOps

-> Founding Engineer at Algotest (YC 2022)—converted their entire web platform to mobile and built hybrid architectures

-> Built a complete employee engagement app at SchbangQ using React Native

-> Shipped revenue-driving features at OYO that generated $64k annually

What I love most is the 0-to-1 phase—taking an idea and turning it into something tangible. I'm comfortable jumping between frontend animations, backend APIs, CI/CD pipelines, and everything in between.

I believe the best products come from understanding both the technical constraints and the user's needs. That's the lens I bring to every project.

Always excited to chat about startups, technical architecture, or that one bug that's been haunting you for days.
