What I'm looking for

I want to work on systems where long-running tasks and large datasets shouldn’t block users—building UIs, APIs, and async pipelines with queues, caching, and streaming updates, from architecture to testing, CI/CD, and production support.

At Sber, I delivered the React and TypeScript frontend for an enterprise LangChain-based AI agent platform’s first production release, including a React Flow canvas editor and production-ready streaming with SSE. I also integrated it as a Module Federation microfrontend and implemented end-to-end authentication/authorization with a proxy-authentication backend mode.

Earlier, at Main Information and Computing Center, I built high-load REST APIs and CRUD microservices using Node.js, Express, NestJS, Prisma, and PostgreSQL/MongoDB/Redis. I moved DOCX/PDF generation and electronic-signature workflows from long-polling to BullMQ/Redis background jobs with progress updates over WebSocket, and I developed an Excel-like React/TypeScript editor backed by JSON schemas and Web Workers.
