Ruby on Rails developer / SaaS developer / web application developer for technical audit
Ihor and his team did a great job reviewing our Ruby on Rails Saas application. He carefully analyzed the codebase, architecture, integrations, billing system, database, and front end, and provided a clear report with findings and recommendations. Communication was super smooth, highly recommend this guy and his team for any Ruby on Rails or SaaS development work.

Security / Code Improvements for Web Based Application
Working with Ihor has been fantastic. He is an exceptionally clear communicator; honest in his work and estimates and works hard to ensure a quality output. He's provided quick turn-around on requests and always keeps me updated as to his progress. I highly recommend working with Ihor - he's proven to be very skilled at Ruby/Rails; security audits; bug fixes/monitoring and now front-end development as well.
