From frontend to API.

Frontend, backend and interfaces.

On the frontend I work with React and Next.js, including back-office and admin applications. On the backend I use Node.js with Express and Parse Server, as well as Go. I connect databases such as PostgreSQL, MongoDB and MySQL and integrate authentication with Keycloak and OpenID Connect. Real-time communication via WebSockets and the Matrix protocol is also part of my practice.

• Web applications and back-office tools with React and Next.js
• Backends and REST APIs with Node.js, Express and Parse Server
• Services and integrations in Go
• Database integration with PostgreSQL, MongoDB and MySQL
• Authentication with Keycloak and OpenID Connect
• Real-time features with WebSockets and Matrix
• Evolving existing applications and personal code reviews

Faster development. Effort under control.

From your requirements I develop the technical concept and the structure of the application. I use AI as a tool to analyse large codebases and logs faster and to write code to my specifications. My aim is to build applications faster and economically. To do this, I prepare the necessary information, scope tasks and plan verifiable steps. Suitable tools, models and targeted context help avoid unnecessary token usage and rework. Technical decisions, integration and checking function, security and maintainability remain with me.
