Ruby

I'm a Ruby developer with over 8 years of professional experience. I'm an eloquent programmer with a deep knowledge of both standard library and most industry-standard gems.

Ruby on Rails

I enjoy writing maintanable, scalable, well tested code in complex applications. I equally like writing both new feautres and refactoring existing ones.

PostgreSQL

I have a knack for solving complex SQL-related issues. I can help you with performance optimisations, I can prepare some custom triggers or utilize one of the postgres extensions.

JavaScript

I'm familiar with modern JS ecosystem. I can write ES6+ code or help you with a transition to TypeScript.

...You name it!

I'm always open to new challenges.

I have experience with React+Redux applications. I can create new one from scratch or work on an existing one.
