What I'm looking for

I’m looking for backend-focused work where I can build event-driven microservices, REST APIs, and distributed systems—ideally involving blockchain or real-time pipelines—while owning architecture, reliability, and test quality.

I’m a software engineer with hands-on backend experience across Go, Java, and TypeScript/Node.js, focused on RESTful APIs, event-driven microservices, and distributed systems.

Most recently, I architected and built a bidirectional cross-chain bridge and contributed to Go-based protocol work including P2P networking, REST/RPC communication, and state synchronization. I also led a small team to design the end-to-end user flow for token staking.

I’ve implemented event-driven pipelines with Go microservices and Rust indexers to monitor, filter, and process blockchain events in real time. I also built comprehensive unit and integration tests in Dockerized environments for critical bridge and cryptography components.

Earlier, I developed a production-like full-stack web application using Next.js and Tailwind CSS, with Node.js/Express.js and a PostgreSQL backend via Prisma. I owned auth flows, API design, secure user data handling, and integrated AWS S3 for scalable media management.
