What I'm looking for

I’m interested in tackling problems in software systems and maintaining the reliability of their operation.

At Sonnen, I developed backend services in Elixir, Go, and TypeScript for distributed systems managing over 100k connected systems. I also implemented containerized services with Docker and message brokers, alongside PostgreSQL.

At Ubiwami, I developed backend services and fullstack websites for internal workflows and customer deliverables. I managed projects through implementation, testing, and production support.

As a contractor with Zuse Institute Berlin, I contributed to BeanPea, an open-source integer linear programming solver. I also developed BeanPea as a project using multithreaded parallel programming.

My projects include a Java-based distributed file system using consensus algorithms and an authentication and authorization service built with Spring Boot and PostgreSQL. I’m interested in tackling software systems problems and maintaining reliable operation.
