What I'm looking for

I am seeking backend/full-stack roles in fintech or AI/ML where I can lead architecture, modernize legacy systems, and build secure, extensible platforms.

I am a mathematical-technical software developer and Full Stack Developer with a Bachelor in Applied Mathematics and Computer Science, extensive fintech experience, and strong skills in AI/ML, Java, and web architectures. I have led reimplementations from legacy desktop to hexagonal Spring Boot web architectures and built production-ready backends and integrations.

My work includes developing a Java-Python adapter (JaPy), a Monitoring-Management-System for freelancers, and a trading engine for backtesting and live execution. I focus on robust software design, test automation, and secure, extensible systems that integrate with third-party services.
