A web application is often the heart of a business today. It needs to work reliably, grow with your business, and still be easy to evolve years later. That's what Web Engineering at Felix Schmidt Software is all about.
Clean architecture, high performance, scalability, and long-term maintainability form the foundation of every solution. Modern AI accelerates development significantly. The decisive difference, however, is the engineering behind it — so that your software not only impresses today but is also the right decision tomorrow.
From customer-facing platforms to internal tools — if it runs in the browser and carries real business logic, it's my home turf.
Web applications with AI built in — assistants, document intelligence, and search that understands your data.
From idea to a subscription product billed via Stripe — built lean as an MVP first, architected to grow into the real thing.
Give customers a secure place for their data, documents, and orders — self-service instead of email ping-pong.
Appointments, resources, or rentals — booked online, paid online, in sync with your calendar and your team.
Replace the spreadsheet chaos: admin panels, dashboards, and workflows tailored to how your team actually works.
Connect what's separate today: clean REST and MCP interfaces between your shop, ERP, CRM, and everything else.
Your web application is built under clear technical ownership — from concept to operation. Where additional expertise is useful, I complement the project with experienced senior specialists from my network. For you, the collaboration remains simple: short paths, consistent decisions, and a central point of contact.

Every business is different. Processes, existing systems, data, and design need to work together seamlessly. That is where custom software starts. Modern AI accelerates delivery significantly. Solid software engineering ensures the result stays performant, secure, and maintainable for the long run, fully in your ownership.
Whether you want to develop a new web application or reinforce your existing product team — you get engineering with a focus on quality, speed, and long-term maintainability.
I develop web applications that move your business forward — from the first idea through architecture and development to deployment. One partner, clear ownership, and a solution that grows with your business.
I support product teams where experience makes the difference: complex frontends, technical architecture, and the sustainable evolution of modern web applications.
Engagements are scoped as project blocks or limited hourly retainers, not full-time staff augmentation.
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.
"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.
Every successful software project starts with the right decisions. That is why we do not just build features, we follow a clear process from the first idea to long-term operation.
We start with your business, not with technology. Together we map goals, workflows, and bottlenecks. The result is a clearly prioritized scope, so we build exactly the software that creates real business value.
Strong architecture saves time and money later. Before writing code, we design data model, system architecture, integrations, and security concept. This creates a technical foundation that stays reliable and scales with your business.
Short iterations, early feedback, and full transparency. You get working versions regularly and can steer priorities at any time. This way, the solution evolves with your requirements instead of surprising you at the end.
A clean launch is only the start. After deployment, you get full access to code, infrastructure, and documentation. Whether you run the application yourself or continue with me, the decision always stays in your hands.
