With over 8 years of hands-on experience in Java enterprise technologies, working across both domestic and international companies with excellent reputations. As a Certified Kubernetes Administrator (CKA), I bring a unique blend of backend development and cloud infrastructure expertise to the table, helping businesses build resilient, scalable systems.

Committed and Delivery-Oriented

When I commit to a timeline, I ensure the work is done before the deadline, maintaining my promises with the highest priority. I have experience working in both small and large teams across Asia, Europe, and America.

Quality and Attention to detail

Specializing in delivering high-quality, efficient software solutions for sensitive industries. Proven track record in achieving up to 50% performance improvements while maintaining at least 80% test coverage to ensure exceptional code quality and reliability.

Driven by curiosity and learning

I take a steady approach to learning, valuing deep understanding over speed. While I can adapt quickly when needed, I believe continuous learning—regardless of its relevance—broadens my perspective and enhances my problem-solving skills.
