@dmitriiosipov
I’m a backend software engineer building distributed systems, APIs, and developer tooling at scale.
GermanyWhat I'm looking for
I’m a backend software engineer with 5 years of experience building distributed systems, REST and GraphQL APIs, data indexing pipelines, event-driven architectures, and developer-facing TypeScript libraries. I’ve owned the full lifecycle—from architecture to deployment—and focus on production reliability and clear developer experience.
I’m the sole author and maintainer of gear-js/api and sails-js, serving ~1,800 weekly downloads at peak. I’ve built and led backend services (including a Gear Idea backend with a data indexer, REST explorer API, program metadata storage, and token faucet service), implemented Coinbase Rosetta API integration in TypeScript, and led a cross-chain bridge using a multi-node Listener/Relayer/Signer architecture with RabbitMQ-based consensus and threshold signature validation. I’ve also mentored and coordinated 4–5 engineers, driving engineering best practices across CI/CD.
