## About

```text
At Singapore Telecommunications, I designed, developed, and operated enterprise CRM applications, building REST APIs and modernising services with Java, Spring WebFlux, PostgreSQL, Kafka, and React.js. I also led a MariaDB-to-PostgreSQL migration of more than 50 million records, with zero data loss and minimal downtime, reducing migration time by 60%.

Across projects including Chompchat and DANA Indonesia, I delivered backend APIs for product, order, and merchant workflows, including Java/gRPC payment integrations and production use of the OpenAI API. At Konekseed, I architected backend and production infrastructure and improved the deployment workflow, reducing deployment time by 40%.

Earlier, I led engineering delivery at PT Kharisma Nusantara Teknologi and served as Scrum Master for five years while remaining hands-on with Java/Spring and Go. I’m also building OpsFlow and FieldFlow as independent R&D projects to demonstrate current full-stack, API, testing, and production-hardening practices.
