Summary

Roman Pellya

I am able to manage a project from scratch: from designing the business logic and APIs to setting up CI/CD and a full testing cycle. I structure processes so that the team works seamlessly, and quality is not the responsibility of any one individual, but a shared responsibility. When it comes to Frontend development, I focus on more than just the visuals: architecture, application performance and ease of future development are of critical importance to me.
