What I'm looking for

I seek backend- or full-stack roles building high-concurrency, scalable systems with strong DevOps support, Web3 opportunities, and collaborative teams.

I am a Full Stack Developer with 5+ years of hands-on experience building web, mobile, and desktop applications for enterprise clients, including large airline systems. I consistently deliver performant, scalable solutions, focusing on pixel-perfect UI, responsive dashboards, and 3D digital twin integration.

My backend expertise spans Java (SpringBoot), Node.js, Go, Rust, and databases such as MySQL, PostgreSQL, MongoDB, and Redis; I architect high-concurrency systems (1000+ QPS) using sharding, read-write separation, and layered caching to achieve sub-second responses. I also automate DevOps workflows with Docker, Linux shell scripting, and custom tooling to accelerate development.

I have led integrations with WebRTC, WebSocket, PDF/XML processing, and web-to-desktop interoperability, and I leverage AI tools to boost productivity. Notable deliveries include airline management systems, a low-code Rust scaffolding generator, a Rust WebSocket server, and a one-click Go-based Web3 deployer.
