Message

At Deutsche Bank, I design, develop, and maintain backend services in a large-scale microservices architecture with strict reliability, security, and regulatory requirements. I take ownership of backend components and contribute to design decisions, production stability, and long-term maintainability.

I also participated in migrating multiple services from OpenShift 3 to OpenShift 4, addressing deployment and operational challenges. I work with product, infrastructure, and SRE teams to troubleshoot production issues in distributed systems.

At NEXPLORE, I designed and developed APIs from scratch for an IoT platform in the construction industry. I contributed to backend architecture decisions, CI/CD pipelines, and cloud deployment on Microsoft Azure.

Earlier, I developed web applications for IoT and retail at ITI - Instituto Tecnológico de Informática and Capgemini, and an e-commerce web application at Seidor. At Jozef Stefan Institute, I contributed to Python-based tools and assisted with Linux system administration in an international research environment.
