Where I’vebeen.
PT. Rama Putra Djaya
Backend System · Distribution Management System · Lezza brand website
- Build and maintain Go backend services with a layered architecture (domain, repository, use case, delivery) that keeps business logic apart from framework and persistence concerns.
- Implemented hierarchical RBAC covering authentication, permissions and record-level data scoping, deny-by-default.
- Made write paths safe under production load with transactions, row-level locking and idempotency, eliminating duplicate records.
- Use Redis for caching and async jobs, including atomic counters that resolved a high-concurrency race condition in production.
- Integrated partner services with configurable, resilient handling of unreliable and at-least-once delivery.
- Developed the frontend of an internal DMS used by multiple operational roles, and the consumer-facing Lezza brand website.
