👋 Hi, I'm Vishnu — a Senior Full-Stack Engineer & AI Integration Specialist with 8+ years building production software for banking, healthcare, and enterprise clients (IBM, TCS, HCLTech). Over the last 2 years I've gone deep on applied AI: RAG pipelines, multi-agent systems, and Model Context Protocol (MCP) — shipping real systems like a multi-agent customer support platform that cut manual processing by 50% and lifted first-call resolution to 85%, and an MCP-powered medical data app that cut report delivery time by 96%. Core stack: React.js, Node.js, Python, FastAPI, LangChain, RAG, Agent Orchestration, SQL, Docker, GCP/IBM Cloud. On Topmate I help engineers, founders, and teams with: • Resume & LinkedIn reviews for full-stack/AI roles • Mock interviews & interview prep (React, Node, system design, AI/LLM) • Career guidance for breaking into AI engineering • Freelance builds — web apps, AI agents, RAG chatbots, MCP integrations Book a call or drop a Priority DM — I reply fast and I'm happy to be direct about what will actually move your career or project forward.
