About
Denys Bilyi
Almere, Netherlands · Open to remote · Building full stack since 2023
I'm a junior/middle full stack developer working across the whole stack — React, Next.js, Node.js, Python, PostgreSQL, MongoDB, and deployed infrastructure. I care about the full picture: clean APIs, reliable data layers, and products that hold up under real-world use.
Most of my work has been personal projects taken from idea all the way to production solo — which has pushed me to own every layer: schema design, API structure, auth, deployment, and everything in between.
Core skills
How I work
- I ask questions early, communicate blockers clearly, and try to leave the codebase better than I found it.
- I think about the full system — not just the feature in front of me. API contracts, data validation, error handling at every layer, and what happens when something fails upstream.
- I take feedback well and give it constructively. I work best when there's clarity on priorities and room to push back when something doesn't seem right.
What I'm working on improving
Currently deepening my knowledge of system design, database optimisation, and backend testing patterns. I'm deliberate about growth across the full stack — not just shipping — and I track what I'm learning the same way I track what I'm building.
What kind of team I thrive in
Teams that value craft, move with purpose, and treat code reviews as learning opportunities rather than gatekeeping. I want to grow alongside people who have strong opinions about doing things well.
Want to work together?
I'm currently open to full-time roles and freelance engagements. If you're looking for a full stack developer who cares about both the code and the product, I'd like to hear from you.
