I’m a backend-focused Node.js engineer with 3 years of experience building scalable APIs and data-driven applications. I’ve worked extensively with Node.js, MongoDB, REST APIs, and cloud-based services, focusing on clean architecture, performance, and reliability. In addition to core backend work, I’ve built AI-powered features using LLMs and Retrieval-Augmented Generation (RAG), including integrating vector databases, designing ingestion pipelines, and exposing AI workflows through APIs. I enjoy collaborating with distributed teams, taking ownership of features, and building production-ready systems that solve real business problems.…I’m a backend-focused Node.js engineer with 3 years of experience building scalable APIs and data-driven applications.
