“I met Ivan while I was working as a CTO of Allegro. He applied for the job of a software engineer, got feedback on what to improve, returned in a year and aced the job interview [edit: I stand corrected on this - the part starting in "returned..." should read "advised to return in one year, returned in four months..." as you see Ivan is even more awesome :)] He proved to be a competent, diligent software engineer, able to design and to implement solutions for complex problems. Our paths closed again when he started supporting www.airly.eu with his skills and insights (I am an advisor and an investor there) - his work still powers Airly's presentation and prediction of air pollution. He is well regarded by the team and would be welcomed back. You should consider it a privilege if Ivan decides to work for you.”Wojtek Burkot, Co-Founder and Chief Physics Officer @ BEIT
“At Airly, when we didn't know what we really wanted, we were simply asking for a Java developer. Thankfully, Ivan wasn't just a Java developer. His extremely wide knowledge in many aspects of IT (from DevOps through programming to business) allowed him to built highly scalable, available, reliable, and fast solution for our Air Quality Monitoring System. Ivan is passionate about his field. He constantly improves his knowledge and shares it with the community (by being a speaker at conferences or contributing to open-source code). Ivan rarely goes offline, so you can always count on him when something unexpected happens. I would definitely recommend working with Ivan, but not too much because we want him back! ;)”Michał Kiełtyka, CTO @ Airly
“Ivan is a very passionate Software Engineer. He was always capable of foreseeing potential problems in a system. Tackling designing and architecture problems with him was always a pleasure - he is open-minded and able to see a bigger picture. ”Tomasz Lelek, Open Source Software Developer @ Dremio
“I had the pleasure to work with Ivan on a highly visible project to accelerate key Alexa ML services at Amazon. Ivan was one of the technical leads to plan, architect, code and optimize the software stack tuned for the new accelerator backend. Ivan is easy to work with and a great team player. He is proactive and communicates clearly across large cross-functional teams. Ivan's software design skills are impressive as well. Ivan would be an asset to any organization.”Vignesh Vivekraja, ML Engineer @ Amazon
“Ivan is a motivated and experienced software developer. He is open to meet engineering challenges. But I enjoyed to work with Ivan, not only because of his technical abilities, but also because of his great attitude to people and friendly atmosphere he created.”Marcin Neyman, SDM @ Amazon
“I had a pleasure working with Ivan on several projects. During that time he was proving me that Machine Learning concepts can be easily explained, that there is no such term in Software Development as "impossible" and that PM can be perceived as a team member not developers worst enemy :). Great developer, even better colleague. I'm sure he will be great addition to any team with his energy and joy of life.”Tomasz Hliwiak, Principal TPM @ Amazon
“Ivan is a fast learner. As his onboarding buddy in Amazon I was impressed how quickly he is able to grasp new concepts. He was ready to independently contribute to our codebase in no time. Ivan has excellent communications skills and it was a pleasure to work with him.”Piotr Kruk, Software Engineer @ Amazon
“I've worked with Ivan in a team for a while and always appreciated his passion for work. His technical knowledge is very impressive and he has a knack for explaining the complicated things in an easy manner. Ivan also has a lively personality which meant that I enjoyed meeting him both at and outside of work :)”Andrzej Pomirski, Software Engineer @ Amazon
