I am currently leading the Rakuten Point Outward Exchange Project, creating a secure integration between Rakuten Points and the Syla Rimawarikun Coin API to safely exchange a billion points per year.In my previous roles, I have delivered scalable, reliable, and cost-effective solutions for various projects, such as the Point Calendar API, which increased user engagement by 10%, the data aggregation batch process, which reduced operational costs by 50%, and the single-page application and integrated headless CMS, which reduced project expenses by 60%. I have also demonstrated proficiency in using modern technologies, such as Java, Spring Boot, MySQL, PostgreSQL, Redis, React, Next.js, TypeScript, Docker, Kubernetes, Terraform, and CircleCI. I am passionate about learning new skills and staying updated with the latest trends and best practices in the tech industry. I hold certifications in Linux administration, Java microservices, and Japanese language proficiency.
