What I'm looking for

I am looking for a challenging role that fosters innovation and teamwork, with opportunities for professional growth and development.

I am a Senior Java Developer with over 9 years of experience in building enterprise systems. My expertise lies in Java, Spring Boot, and microservices architecture, where I have successfully led projects that optimize performance and enhance system reliability. I have a proven track record of mentoring teams and delivering robust backend systems that meet business needs.

At Allianz Technology Thailand, I spearheaded the development of microservices using Spring Boot and WebFlux, achieving a remarkable 50% reduction in API response times through performance tuning. My role involved architecting event-driven flows and improving CI/CD pipelines, which significantly reduced downtime. I am passionate about sharing my knowledge and have actively mentored junior developers, fostering a culture of continuous improvement.

My previous experience at GL Finance and BDKtel further solidified my skills in building REST APIs and modernizing legacy systems. I thrive in agile environments and am committed to delivering high-quality software solutions that drive business success.
