Experienced Senior Backend Developer Needed We had an incredible time working with Roman. It can be difficult to find a backend developer you can trust to get the job done, but Roman always delivered as promised and he also brought forward good ideas. He executed all our tasks in a professional and swift manner, and the team found him to be a great team player.
We would definitely recommend him if you are looking to hire a backend developer for your team. Thank you very much!

Scaling an enterprise application requir​​es more than just a coder; it demands an architect who understands how to bridge high-load systems with seamless user interfaces. With 16+ years of engineering experience and a decade focused on the Node.js ecosystem, I help companies build resilient, business-ready solutions.

As a backend developer, I don't just "make it work"; I design systems for High-Load and global traffic. My background in React allows me to understand the data requirements of modern interfaces, preventing bottlenecks before they happen. Whether you need a dedicated Node.js developer for a specific module or a Full Stack developer to lead a full-cycle project, I bring a professional, security-first approach to the entire development lifecycle.
