Senior Java Freelance Software Developer (Interim / Part-time)
Experienced Java freelance software developer with a strong focus on reliable backend systems, clear architecture, and maintainable solutions. I support organizations temporarily with the development, optimization, and transfer of software, with minimal ramp-up time and maximum added value.
I enjoy working in environments where quality, tranquility, and structure are important: existing codebases that need further development or cleanup, teams that temporarily need extra capacity, or projects that are being brought to production. I combine hands-on development with a keen eye for architecture and long-term maintainability.
What I help with
• Development and further development of Java backends
(e.g., Java, Quarkus, Spring)
• Improving structure, performance, and readability
• Preparing and supporting pilots, demos, and releases
• Temporary reinforcement of development teams
• Knowledge transfer and technical onboarding
Methodology
• Calm, reliable, and structured
• Defined scope and clear agreements
• Practical and solution-oriented
• Independent, but works well with teams
Availability
Available as a freelance/interim Java developer for 16–24 hours per week, preferably for temporary or clearly defined assignments.
