Backend Engineer · Go · Distributed Systems · Game Server Architecture
I build backend systems from scratch — game servers, security automation tools, and platforms for social impact. Currently focused on real-time multiplayer infrastructure, AI orchestration, and accessibility tech in Indonesia.
🎮 Game Backend Engineering — Custom Go backends for multiplayer games (MMORPG, card game), real-time state sync via Nakama & WebSocket, Redis resilience patterns, IAP validation pipelines
🏗️ System Architecture — Domain-Driven Design, Circuit Breaker, SAGA patterns, event-driven microservices, distributed data stores (Cassandra/ScyllaDB, Redis, PostgreSQL)
🔒 Security Automation — DevSecOps tooling with Trivy, Nuclei, Gitleaks, ZAP — orchestrated scanning pipelines in Go
♿ Accessibility Tech — Building disabilitasku.id, a platform for people with disabilities in Indonesia, powered by AI

- Built custom Go game backends from scratch (no frameworks) for an Android MMORPG and a Gwent-style card game
- Migrated production systems from Laravel to Go at scale
- Designed take-home assessments and hiring pipelines for backend engineering roles
- Shipped sprint demos across Nakama game backend, AI orchestration, and WebSocket services
