Hrayr Petrosyan

I design and build reliable, cloud-native software — from resilient backend services on Azure to thoughtful, accessible frontends in React and Next.js.

I enjoy the overlap of architecture, hands-on implementation and mentoring — helping teams ship with confidence instead of ceremony.

Most of my work lives at the intersection of TypeScript, React/Next.js and cloud-native backends on Azure and Kubernetes. I’m comfortable owning a service from design and implementation through to deployment and observability.

Let’s talk about your next project or team

I’m open to roles where I can help teams ship reliable software, improve engineering practices and mentor others.

The best collaborations I’ve had combined clear business goals with enough technical freedom to pick the right tools. If that resonates, I’d be happy to chat.

I’m comfortable working across architecture discussions, hands-on implementation and mentoring less experienced engineers.
