About Mario

I support companies and individuals in planning, implementing, and further developing software projects. Part-time, flexible, and reliable – with a focus on clean, maintainable solutions and realistic technical assessments.

My focus lies in developing individual software solutions, supporting ongoing projects, and maintaining and optimizing existing systems. This includes web applications and APIs, automations and scripts, extensions to existing software, as well as analysis and refactoring of codebases.

I work pragmatically, solution-oriented, and with clear communication – without unnecessary complexity. The goal is to create functional and sustainable solutions that integrate meaningfully into existing structures.
