Frontend Engineer

I build products
people love to use.

Specializing in advanced JavaScript, scalable state management, and pixel-perfect UI. I turn complex ideas into high-performance web apps that actually ship.

About Me

Hayk Shirinyan

Frontend engineer based in Armenia, focused on building fast, accessible, and beautifully crafted digital products. I write clean Vanilla JS and architect projects with the maintainability of a production codebase from day one.

Every project is built to a standard I'd be proud to demo to any Tech Lead — clean architecture, zero shortcuts, production-ready from day one.
