At PT. Softwareseni, I deliver backend and full-stack features for Australian clients across security risk assessment, time tracking, and university admissions platforms. I work on React.js, TypeScript, Node.js, Yii2, and Quarkus applications from planning through production.
For an admissions platform, I improved an export of hundreds of thousands of records from about 10 seconds to about 2 seconds using partial bulk streaming. I also reduced large-table loading from about 2 seconds to milliseconds with OpenSearch.
I implemented about 90% of Kafka-based inter-service messaging, including failed-event retries, and refactored more than 1,000 lines of backend logic for maintainability. My work also includes integrations with AWS, GCP, and Azure services.
Previously, at PT. Sarana Media Selular TDC, I maintained and extended internal voucher-sales workflows using Laravel, Bootstrap 3, and MySQL. At IT Courses, I delivered one-on-one web development training in Laravel and CodeIgniter.
