Freelance Software Architect & Senior Software Engineer | PHP, Java, TypeScript | Remote

I help companies design, evolve and modernize complex business software.

My strength is understanding domain-specific requirements quickly and turning them into maintainable, scalable and pragmatic software solutions — from architecture, API and data model design to hands-on implementation.

Focus areas:
• Software architecture & technical concept development
• Backend and API development
• Service-oriented architectures & integrations
• Modernization of mature existing web applications
• Full-stack development with PHP, Java and TypeScript
• Translation of complex business processes into clean software structures

Technologies:
PHP, Laravel, Symfony, Java, Spring Boot, TypeScript, JavaScript, Angular, Vue, React, REST APIs, relational databases, message queues, Docker, CI/CD.

I work remotely, independently and in a structured way — especially on projects where technical thinking, architecture decisions and long-term maintainability matter as much as implementation.

Languages: German native, English fluent / business fluent.

Part-time available · Remote · Preferably long-term collaboration or clearly scoped architecture / development tasks

Skills: Software Architecture, Backend Development, API Development, PHP, Java, TypeScript, Software Engineering, System Design, Distributed Systems, Service-Oriented Architecture, Laravel, Symfony, Spring Boot, JavaScript, Angular, React, Vue, REST APIs, Message Queues, Docker, Kubernetes, CI/CD, MySQL, PostgreSQL
