Hi, I’m Asterios Lentzos, a results-driven Java Software Engineer with close to four years of hands-on experience building scalable backend systems in the financial domain. I’m proficient in Java, Spring Boot and microservices, and I thrive on delivering high-performance, fault-tolerant solutions under tight deadlines. I enjoy collaborating with cross-functional teams to turn complex requirements into clean, maintainable code and well-architected services. Recently I contributed to a Push Notification Management System for a retail environment, designing an Android component and integrating location-based messaging into a larger ProximIoT project. I’m passionate about clean architecture, continuous improvement and using observability to shorten incident resolution times. In my spare time I explore cloud-native tooling and continuous delivery practices to keep backend systems robust and scalable.
