AI Engineering Advisory
AI changed how I build software almost overnight — from writing every line by hand to orchestrating agent teams that ship production code. I bring that hands-on experience into your engineering org: agent frameworks, guardrails, and workflows that actually stick, not a slide deck. Practiced daily with Claude Code, on real projects at Allianz, Deutsche Telekom, and PEAX.
Full-Stack SaaS & AI Product Development
You have a product idea — I deliver the working SaaS. Full-stack, from database to UI. Powered by Claude Code and agentic AI development, I ship complete products in a fraction of the usual timeline. AI features like RAG pipelines, intelligent agents, and workflow automation are built in from day one — where they create real value.
Senior Frontend Engineering
A decade-plus building production frontends for millions of users, primarily with Angular, NgRx, and Nx Workspace — still my go-to stack for teams in finance, insurance, and the public sector, even as most of my new build work happens with AI agents. Accessible frontends (WCAG 2.1, ARIA, screen reader support) ship by default, not as an afterthought — increasingly a hard requirement under the European Accessibility Act. I join existing teams and get productive fast.

What clients say about working with me
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.
