Summary
Dimas Rullyandanu is a technical lead with 12 years of hands-on experience building and scaling full-stack systems across payment, transport, and marketplace domains. He combines deep backend expertise (Go, Ruby, Rust) with frontend and DevOps skills—having architected APIs, rebuilt admin panels in React/Next.js, and led migrations that cut latency and costs by an order of magnitude. Dimas has run teams from zero-to-scale and operated services handling tens of thousands of daily transactions and spikes above 50k requests per minute, while also driving platform-wide observability and testing standards. Technology-agnostic and pragmatic, he routinely ships end-to-end solutions and reusable libraries that reduce defects before integration. Based in Tokyo, he’s as comfortable rewriting monoliths into microservices as he is mentoring new hires and shaping hiring decisions.
