Full-Stack C# .NET Core software engineer at Foxway
I had the pleasure of working with Leonid Oleksiuk on a project where he built a new product from scratch.
He set up the product’s infrastructure and built a flexible, scalable software platform.
Additionally, he was responsible for designing and implementing the database architecture, along with developing the necessary data models.
Throughout the project, he took full ownership, conducting thorough research and providing the best solutions. His ability to collaborate across departments ensured smooth project execution. He consistently met all deadlines and delivered high-quality work.
I highly recommend Leonid as a skilled, self-sufficient, and reliable full-stack developer and technical lead.
