Service 01
Full-Stack Development
Production-ready web applications, APIs and integrations with maintainable architecture – aligned with the existing system, team and project goals.
What this means in practice
I translate business requirements into maintainable architecture and deliver frontend, backend and integrations as a coherent whole. Technology decisions account for the existing system, the skills within the team and ongoing operations.
- 01
Frontend
Component-based web interfaces as single-page or server-rendered applications – responsive and designed with load performance and accessibility in mind.
- 02
Backend
REST APIs and services with Node.js, NestJS, Kotlin or PHP, with database access through TypeORM, Doctrine or direct SQL.
- 03
Integration
New functionality connected cleanly to existing systems, external APIs and cloud services – including projects that start with an established codebase.
How I work
I begin by clarifying the business goals, system boundaries, operating requirements and risks. This creates a sound basis for transparent architecture decisions and a useful first delivery scope.
Short iterations, early feedback, code reviews and focused tests make quality visible throughout development and reduce rework later.
To me, AI-assisted tools are tools like any other: I use them deliberately, for example for research, tests or recurring tasks. Architecture, decisions and code review remain my responsibility, and confidential data only goes into tools you have approved.
