In 7+ years building Go microservices, I've reduced medical verification attempt rates by 23%, maintained notification infrastructure serving 11 million users, and owned compliance platform delivery across distributed teams. Currently contributing to a 21+ microservice quick-commerce platform at Astro. What I deliver: - Reduced medical verification attempt rates by 23% and rejected requests by 31% at Kitabisa.com through systematic backend optimization - Maintained notification services and integrated monolithic legacy systems with notification architecture at Flip, serving 11 million users - Improved code quality by 40% through comprehensive unit testing at Tokopedia across campaign services (flash sale and slash price) - Owned end-to-end delivery across 5+ repositories at FrankieOne, shipping from RFC to production in a distributed remote team - Currently contributing to a polyglot microservices platform (21+ services) at Astro using Go, Java, gRPC/Protobuf Core expertise: Go (Golang), distributed systems, microservices architecture, gRPC, REST API design, Kubernetes, AWS, Terraform, PostgreSQL, Redis, Kafka, RabbitMQ. Expanding into full-stack with React, TypeScript, and Vue.js. I accelerate delivery through AI-assisted development with Claude Code, Codex, Hermes, OpenCode, and Windsurf, with 2,900+ GitHub contributions this year. Notable projects include a GPU-accelerated semantic code search engine (Python/ONNX), an AI-powered CV evaluation service with full observability (Go/Vue), and high-concurrency systems with comprehensive chaos testing. Open to remote backend and platform engineering roles worldwide, especially Go-centric distributed systems. Experienced working across time zones with distributed teams (most recently with FrankieOne, Australia). Comfortable with asynchronous communication, technical RFC writing, and self-directed delivery. GitHub: github.com/fairyhunter13
