About Alex Devero
Alex Devero is a Senior Frontend Engineer specialising in React, Next.js, and TypeScript, based in Prague and working across the EU — currently a Frontend Tech Lead. He builds like a founder: he co-founded Persoo (a Czech e-commerce personalisation startup acquired by Luigi’s Box in 2024) and was an early engineer at Supernova, the first Czech startup accepted into Y Combinator (2019). That means he leads React and Next.js frontends with an owner’s product judgment, not just an implementer’s.
Over 10+ years he has built and scaled products for teams at CDN77, Digitoo, and more, pairing deep frontend engineering with a strong product-design background. The result isn’t just shipped features but interfaces and architecture that hold up as a product grows: reusable components, stable UX, and well-defined domain boundaries.
What I do now
As a Frontend Tech Lead, I set frontend architecture, raise code quality, and help teams ship complex React applications with confidence. My focus is on reusable components, stable UX behaviour, performance, and well-defined domain boundaries — the things that keep a codebase maintainable past the first release.
How I work
I’ve made the architecture calls that decide whether a product scales — and, as a founder, the ones that decide whether a startup ships at all. I optimise for the decisions that compound: clear domain boundaries, reusable components, and a codebase the next engineer can move through quickly. Curiosity gets me to the problem early; judgment gets it solved in a way that lasts.
Outside of code, you’ll usually find me:
- – Training at the gym (my daily discipline anchor).
- – Reading about startups, tech innovation, and the great builders of history.
- – Experimenting with new tools and frameworks to push what’s possible.
Writing & sharing
I believe in sharing knowledge and giving back. On my blog, I write about React, Next.js, frontend architecture, and the lessons learned building products from the ground up. I’m also a lifelong learner — you’ll find my Goodreads filled with everything from software engineering to business strategy and biographies of great founders.
