Colleagues describe him as "I had the privilege of working with Stefan in Instagram Business Communications team for a year. He has a very impressive background in mobile development specifically in Android. When he first joined our team, he quickly ramped up in Facebook & Instagram codebase and tools. He designed, implemented, and shipped many messaging features such as inbox filters, quick replies, and new gallery picker for instagram business users in Instagram Android app. I was impressed by his large amount of contributions to product and the team within a year. Aside from having a strong mobile development, he is a product thinker. His product design experience helped crafting the product. He sets a high bar when it comes to user experience and makes sure all the corner cases are covered as well. Our team had only 1 Android engineer and that was Stefan. His leadership skills helped us build lasting relationship with sister team which has helped delivering our features on-time. He was able to deliver high-quality code on-time and he was there for the team anytime he was needed. He has great mentoring skills that he mentored couple Android folks in our bigger organization and made them better engineers. He made a great addition to our team and I endorse his quality of work, architectural skills and execution. I hope Stefan and I have the opportunity to work again in the future he would be an excellent addition to any team." and "Stefan and I worked closely together at Instagram as Product Manager and Engineer. Stefan is one of the most talented, thoughtful, and passionate engineers I've had the privilege to work with. He's a deep product thinker who works super well with design and product to help shape an experience — he has an eye for craft. There wasn't a single time where I worried about Stefan's products because I know he has a high bar for quality. He moves quickly but knows when to pump the breaks and weigh trade offs. He's a self-starter and builds awesome, lasting relationships with parter teams. He was the first Android engineer on our team and was able to work with other teams to quickly ramp himself up and make impact in record time. His maturity and experience means he's great at influencing teams but always happy to give back to others and flex — he's humble. He quickly earned the trust of our team and became a leader in how we built products, helping us work more efficiently in how we test features. I was really sad learning he planned on moving on... but I'm so excited for what he'll do next. The next company or opportunity he chooses will be lucky to have him and I'd be lucky to work with him again in the future."
