At Kasiro, I’m building and maintaining a multi-tenant POS SaaS for restaurants and small businesses. I develop its backend with Java, Spring Boot, Spring Security, JWT, and PostgreSQL, including services for transactions, subscriptions, reporting, and multi-outlet operations.
At Glints – SPTel, Pte. Ltd., I maintained and enhanced CRM applications for SPTel, primarily focusing on the Customer Backend module. I worked across backend services, APIs, database integration, and reporting for the Staff Portal and Customer Portal.
Earlier, I developed and maintained business applications including Bioplast, Kuul Communities, and Tekno ERP at Teknologi Terapan, PT. I’ve also worked on banking, insurance, trading, and public library applications, and built an online Point of Sale SaaS through Blangkon.com.
