MERN Stack Developer | React.js, Node.js, Express, MongoDB | 4 Yrs Experience | Bengaluru

About

I am a Full-Stack MERN Developer with 3.7 years of experience building scalable, user-focused web applications. My expertise spans the entire development lifecycle, from designing responsive React interfaces to architecting robust Node.js, Express, and MongoDB backends. Lately, I have been bridging the gap between web architecture and Generative AI. I actively build production-ready AI engineering tools, including an independent AI Gateway featuring multi-provider LLM routing and semantic caching to minimize latency and token footprints. I have also engineered a local, privacy-focused RAG system that handles document ingestion and semantic search entirely offline. Core Technical Stack: Frontend: React.js, Next.js, Redux, JavaScript, TypeScript, Tailwind CSS, Material UI Backend & Databases: Node.js, Express.js, MongoDB, RESTful APIs, WebSockets, JWT Authentication AI Integration: OpenAI API, RAG Pipelines, LLM Orchestration, Semantic Caching, Vector Databases Tools: Git, GitHub, Postman, Agile, Firebase, CI/CD I am looking to take ownership of end-to-end features, solve complex backend scaling challenges, and transition into senior full-stack and AI application development roles.
