Hello, I'm Khakim!
Backend & Full‑Stack Developer
I build scalable microservices and APIs with Node.js, NestJS, and Go. Experienced with OIDC SSO, PostgreSQL/MongoDB, Redis, RabbitMQ, and Elasticsearch — delivering reliable web/mobile backends with clean architecture.
About Me
Hi, I'm Khakim — a software developer who enjoys building clean, reliable, and scalable products. I work across the full stack: React/Next.js on the front‑end and Node.js/NestJS or Go (Gin/Fiber + GORM) on the back‑end.
Recently I've been contributing as a BackEnd Developer for INSW (Kemenkeu) via NashTa Group, designing microservices and secure APIs (OIDC SSO) that serve 10k+ daily users. My toolkit includes PostgreSQL/MongoDB, Redis, RabbitMQ, Elasticsearch, S3, and Vault.
I design and ship REST/GraphQL/gRPC services, integrate realtime features, and care about security, testing (Jest/Postman), and performance. I'm a CS graduate and Hacktiv8 Full‑Stack JS alum, continuously learning to stay sharp.
