He always had a good vision of how something should work and could quickly come to understanding and into terms with the complex setup or architecture when he was fixing a bug or implementing a new feature. He easily moved from between PHP, JavaScript, TypeScript, formal linux environment and AWS serverless environments. Excellent team player and a great all-rounder that played a key part in active development of brand new features and figuring out complex bugs. I can easily recommend him for senior developer and architecture positions where understanding, mentoring and good communication skills are appreciated. Thank you! It was a pleasure." and "Risto is one of the smartest engineer I have seen. He is skilled and logical. In addition to that he is very friendly, helpful and flexible."
