I had the pleasure of working with Jonas at OneStudyTeam. Jonas was a senior engineer, and worked as a Clojure developer on our team. More than just a developer, Jonas is an extremely capable problem solver, team member, creative thinker. Jonas was the go-to person on our team for many hard-to-solve problems, as his experience, domain knowledge, and tenacity always made Jonas the person we could rely on in difficult situations. Jonas also brings a great deal of levity to a team, and is a joy to work with. I'd strongly recommend Jonas to any company looking for strong, senior-level talent. ~ Jeff Stickel, Jonas's manager at ReifyHealth

Building software with a good eye to every detail is one of many Jonas's skills that make working with him a pleasure. Jonas is always proactive and precise in conversation about design and implementation. Not once I was surprised how deeply he thinks about possible issues looking at problems from unusual perspective, caring about user of the final product. Overall, he is a great guy to work with, I had many interesting conversations with him and I am always happy to work with him. ~ Sen Mikhalëv, coworker at ReifyHealth

I have enjoyed working with Jonas for more than two years now. In that time I've been impressed with Jonas's software engineering skills, and with his dedication. Jonas has an intuitive understanding of good software design that few of his peers posses. This understanding is likely due to his drive for improvement—both in terms of his personal growth and improvement in software. He is always working towards a goal of efficient, readable code; at the same time, he knows when it's time to be finished because "perfect is the enemy of good."

Jonas takes the requisite time to carefully craft code. Anyone who works with him will notice that he doesn't just "get it working" on the "happy path." Rather, he carefully considers edge cases and possible errors. Additionally, he takes the time to truly understand the requirements (too often I've seen what happens when others are less careful). His careful attentiveness leads to better code, reduced complexity, and overall greater quality of a software product.

Jonas has all the marks of a great engineer—one that adds value to your code. One that works to understand the business's needs. One that helps those around him to achieve great results. I know that Jonas will go to great places and I hope I have the opportunity to work with him again someday. ~ David King, coworker at OrangeSoda and SlingTV

I had the pleasure of working directly with Jonas for 3 years at OrangeSoda. Jonas is a hard working developer who is focused on making sure that his software is of the highest quality and usability for the customer. He doesn't shy away from expressing his thoughts on how to best implement new features and he is always willing to work with others to figure out what will be best for the end user.

Jonas seeks to learn more and improve his skills constantly. He is an excellent developer, but that doesn't keep him from seeking new and better ways to code so that the software will be more robust and higher quality.

I really enjoyed working with Jonas and I'm certain he will be an excellent addition to any company that he works for. ~ Shawn Hart, coworker at OrangeSoda

I have enjoyed working with Jonas, he is an excellent engineer with a keen mind for making good quality software that works properly. He likes to understand the big picture, not just the block of code he is working on today. He goes out of his way to fix technical debt he comes across when possible and encourages others to write long term maintainable code. I think he would be a valuable asset to any software development team. ~ Bryan Lee, coworker at Nike

Jonas has been a very dedicated employee. He has been ethical, loyal and intelligent. He has taken the lead on some of the projects and delivered. He works well the team, a great asset to any company. ~ Douglas Tiejen, Jonas's manager at PolicyTech
