I build scalable full-stack web platforms and modernize enterprise systems.

I've built and scaled enterprise web platforms at Netguru, Future Processing, adesso SE, and STX Next using Node.js, React, Java, Python, PHP, and cloud infrastructure. At Netguru, I improved backend response times by 30% through query optimization and caching while delivering REST and GraphQL APIs, real-time features, and secure payment integrations.

I've led a team of six full-stack developers, architected microservices and event-driven systems, and reduced deployment time by up to 70% through CI/CD automation. I also mentor junior developers and modernize legacy applications into maintainable, cloud-native services.
