What I'm looking for

I am looking for a role that fosters innovation, collaboration, and continuous learning.

As a Senior Java Full Stack Engineer with over 7 years of experience, I have a proven track record of delivering cloud-native enterprise platforms and high-performance web applications. My expertise spans across Java (versions 8 to 21), Spring Boot, and modern front-end frameworks like React, Angular, and Vue. I thrive in fully remote agile teams, focusing on clean code and SOLID principles to meet business needs effectively.

Throughout my career, I have successfully modernized legacy systems, built scalable APIs, and collaborated with cross-functional teams to implement innovative solutions. My recent projects include developing microservices-based backend services and interactive dashboards for clients in finance and utilities, utilizing technologies such as AWS, Kubernetes, and Kafka. I am passionate about mentoring junior developers and continuously improving CI/CD pipelines to enhance deployment efficiency.
