About Me
I build reliable and testable backends that power modern applications.
Final-Year Software Engineering student at Telkom University (GPA 3.83/4.00) with hands-on experience building production REST APIs — 10+ endpoints, 92.5% test coverage, deployed on Azure — using TypeScript, Node.js, Express.js, PostgreSQL, and Docker.
Experienced in JWT authentication, RBAC, database schema design, API testing with Jest & Postman, and CI/CD workflows. Also skilled in QA engineering, DevOps (Kubernetes, ArgoCD), and Flutter mobile development.
