I’m a software engineer focused on building production-grade backend and full-stack applications with Node.js (Nest.js/Express), TypeScript, and React. I enjoy designing clean REST APIs, modeling data with Prisma across PostgreSQL and MongoDB, and delivering secure, well-tested systems with robust observability—often using Jest, structured logging, and CI/CD pipelines on AWS. I also build AI-powered features, including RAG over MongoDB Atlas Vector Search with OpenAI embeddings and LLM API integrations. Recently I’ve worked on real-time collaboration and streaming AI chat experiences (SSE/token streaming, retrieval strategy evaluation, and provider fallback handling), and I’m passionate about maintainable architecture, thoughtful security (JWT/RBAC), and measurable performance improvements.…I’m a software engineer focused on building production-grade backend and full-stack applications with Node.js (Nest.js/Express), TypeScript, and React.
