About
Understand the problem, then write the code.
I'm Danylo, a Java and JavaScript developer who enjoys turning business ideas into software people use every day. I build clear interfaces with React and reliable backend services with Node.js, Java, REST APIs and PostgreSQL.
I care about delivering work that is easy to maintain and about being dependable as part of a team. I want to contribute from day one, take ownership of what I ship, and keep growing with the product and the people building it.
