Bukaha OÜ

Software Engineering & Consulting

Hi, I’m Dmitry. With 18+ years of experience and contributions to Ruby on Rails core, I run Bukaha OÜ - a software consultancy company based in Estonia. I partner directly with businesses to build scalable, maintainable software that actually solves problems and drives growth.

As a father of two daughters and a remote work veteran, I understand the importance of reliability, clear communication, and delivering on promises. I’ve been working remotely for over 13 years, perfecting the art of asynchronous collaboration while maintaining the personal touch that makes projects successful.
