Über Oleksandr

Hi, I’m Oleksandr — a App Developer and Python Software Engineer focused on building real, usable applications end-to-end. I help clients turn ideas into working products: MVPs, internal tools, and full-featured apps with clean architecture and reliable performance. What I can build for you: • Application development (from MVP to production) • Backend for apps: REST APIs, database design, auth, integrations • Automation inside your app: workflows, schedulers, background jobs • Quality & delivery: tests, CI, Linux deployment (optional but available) I don’t just “write code” — I design solutions that are maintainable, scalable, and easy to extend. If you need someone who can take ownership of an app and ship it — let’s talk.
