What I'm looking for

I am looking for a collaborative environment that fosters innovation and offers opportunities for growth in back-end development.

I am a passionate Java Developer with extensive experience in back-end technologies, specializing in microservices and architecture design. My journey in software development has been marked by a commitment to continuous learning and optimizing efficiency in every project I undertake. I thrive in dynamic environments where I can leverage my skills to create robust and scalable solutions.

Throughout my career, I have successfully led teams and contributed to various projects, including CRM development and client portals. My technical expertise spans across Java, Spring, Hibernate, and PostgreSQL, among others. I take pride in my ability to refactor existing systems and implement innovative solutions that enhance performance and user experience.

In addition to my technical skills, I am an avid motorbike traveler, which fuels my adventurous spirit and inspires my approach to problem-solving. I am eager to bring my passion for technology and my dedication to excellence to a forward-thinking company that values innovation and collaboration.
