About

Senior Backend Engineer with over 15 years of experience developing scalable and high-performance systems using Java, Spring Boot, Google Cloud, AWS and Azure. I’ve worked on mission-critical enterprise projects in the public sector, applying agile practices, TDD/BDD, and DevOps principles. Highlights include developing a Java Spring Boot application to integrate and map data from external NPS (Net Promoter Score) APIs, successfully reducing task processing time from 1 hour to 20 minutes using RabbitMQ. I am passionate about clean code, automation, and building resilient microservices architectures. I’m currently open to remote opportunities with global teams where I can contribute my backend expertise, collaborate across cultures, and continue growing in challenging, real-world environments.
