I'm a full-stack developer with 5+ years of experience taking products from MVP to production for US teams. I develop SaaS products, extend existing applications, integrate APIs, and support ongoing development across the data model, permissions, backend, and interface.
Based in Lviv, Ukraine · Europe/Kyiv. Available for freelance work.
Architecture is worked into the program by all the little decisions we made — little decisions that were right, and little decisions that were wrong and corrected.
