What clients say about working with me
Felix and I drove the adoption of AI-assisted software development at PEAX AG. Coding agents are now established across the entire engineering team and have clearly improved time to market. Felix also built the automation for what used to be manual regression testing: a fully automated end-to-end test framework on Playwright that runs the regression suite in minutes instead of days. I can recommend Felix without reservation to engineering teams that want to integrate AI effectively into their development process.
Working with Felix was always very pleasant and productive. The greatest value for me came from the speed and quality of his work, as well as his valuable technical insights and design/usability suggestions.
Felix is an iOS developer with an eye for the big picture and a drive to achieve the best possible result. With Felix, it was possible to generate new approaches and ideas through dialogue, finding a suitable and functional solution for the target audience.
"Extremely quick learner" is the first thought I have when I remember working with Felix. He adapted to working with reactive programming remarkably fast. Both development velocity and code quality quickly raised as he was working with us.
I enjoy Felix' tenacity concerning brainteasers that pop up during work as well as his friendliness and accuracy. During the last years he became not only a very appreciated colleague but also a friend.
His contributions were outstanding and a key factor in the project's success. Felix helped both the team and the client to think through ideas, improve them, and visualize them concretely.
Felix enriched our iOS development team from day one. His extensive experience in the eHealth and MedTech industry helped us make TK-Safe the most successful Electronic Health Record on the German market.
Through his excellent overview and outstanding technical understanding, he significantly contributed to driving the project forward. He excels at bridging the gap between domain expertise and technical implementation.
I came to appreciate Felix as a competent, communicative, and innovative colleague. His personality and work approach were an asset to the team.
Felix's technical expertise enabled the client to meet their deadlines while increasing code quality.
Great engineering practices, very good code quality and quick clear communications throughout our two years together on the Corona-Warn-App. Very recommended!
He is a very sound iOS developer with a strong command of the latest iOS stack. Working together on the Corona-Warn-App, he always tried to come up with out-of-the-box solutions that were really helpful to the project. I would recommend him any day.
I can recommend Felix Schmidt without reservation as an iOS developer. Working together on the Electronic Health Record (ePA 2.0), Felix particularly excelled in his ability to work as a team player. I'm certain that Felix would be a valuable asset to any iOS development team.
A versatile and adaptable software developer. His combination of technical expertise, quick learning, and collaboration makes him a standout developer. I endorse Felix for any project needing a capable, adaptable, and team-oriented developer.
Both professionally and personally, you're in very good hands with him. His extensive experience gives him an excellent analytical eye for client requirements, always thinking beyond the obvious.
An absolute stroke of luck for our daycare center! Three years ago, Felix designed and built our website from scratch — ever since, we wouldn't want to be without his support. With the monthly plan, he takes the day-to-day work off our shoulders: quick questions are sorted out over WhatsApp, new files simply go into Google Drive, and Felix reliably takes care of everything else. For us, it's complete peace of mind!
Felix rebuilt our website from the ground up five years ago, wrote the copy, and has been delivering top results ever since. Thanks to his SEO work, we climbed from #6 to #1 on Google in our region within a few months. For us that means noticeably more inquiries, higher revenue, and years of fantastic support!
