Profile: https://flows.cv/kiril

Software Engineer with 10+ YOE.

— Back end web applications development, documentation/specification, development and support
of standalone libraries for customers’ goals, writing automation tests.

— Strong business understanding, a dialogue is the key.

— Customer Obsession: Help customers to design and deliver working solutions when they have only a vague idea of the final product.

— Combine the best applicable tools for each problem.

— Feel comfortable working with a new codebase, programming language, tool or framework (pretty language agnostic, though Ruby is in my heart I also feel quite comfortable with PHP, JS, JVM languages e.g. Kotlin, having fun with Go/Elixir).

— Enjoy solving code puzzles (Algorithms and Data Structures).
