Hi, I'm Ribin.

BACKEND / AGENT / INFRASTRUCTURE

I'm a backend and infrastructure engineer who takes AI products from a single box to production. At Kuse I own the cluster, orchestration, and multi-channel access for an AI-employee product: I moved a single-box stack onto GKE, unified the messaging channels behind one gateway, and run agent execution with proper observability. Before that I solo-built the real-time multiplayer engine behind a UGC social world with millions of daily active users.

My strength is the kind of systems problem where protocol, concurrency, deployment, and observability all have to be right at once, and I write the code as readily as I draw the architecture. Day to day I work in Go and Python across Kubernetes / GKE, Cloudflare, and AWS, backed by Redis, MongoDB, and ElasticSearch.

Outside work I keep this site: essays, experiments, and small things that actually run. Open to backend, infrastructure, and AI-platform roles.
