Обо мне

Product engineer experienced in architecting, implementing and leading development of complex software solutions - from single-page browser applications to distributed microservice-based systems.

Problem-solver talking on a business language, aligning development with product needs while maintaining development team processes.

My decisions are focused on business value growth yet keeping technological perfectionism when possible.

I prefer a tree-shaped personal evolving and being proficient in many areas of product development – which allows me to coordinate the development across disciplines and have the overall vision.
