About this gig

Hi, I'm Anjali a full-stack engineer with 2+ years of production experience building TypeScript, React, and Node.js applications, plus AI features powered by the Claude and OpenAI APIs.

I don't just wire up a chatbot widget. I build the whole thing: the React frontend, the Node API behind it, the PostgreSQL schema underneath, and the AI layer that makes it useful.

WHAT I BUILD

  • AI chat assistants and agents (Claude API, OpenAI, LangGraph)
  • Full-stack web apps in React 19 + Node.js + PostgreSQL
  • REST APIs, auth (JWT/OIDC), and database design
  • Real-time features with WebSocket and SSE
  • Deployment to Vercel, Railway, or Docker

WHY ME

  • Currently shipping production services on a 15-service platform
  • Live, publicly deployed AI apps I can show you
  • Anthropic-certified in the Claude API and MCP
  • Clean, commented, tested code source always included

HOW IT WORKS

  1. Message me with your idea (free, no obligation)
  2. I confirm scope, timeline, and exact price
  3. You order and I build, with progress updates throughout
  4. You get working code, deployed and documented

Have something specific in mind? Send me a message before ordering I'll tell you honestly whether I'm the right fit.

I am a full-stack engineer with 2+ years of production experience, currently owning a bounded context end-to-end in a 15-service TypeScript/Python platform. I specialize in building Fastify APIs, event-driven messaging on Kafka, React 19 micro-frontends, and LangGraph AI agents. I am equally comfortable designing schemas, debugging Python extraction agents, and shipping high-quality UIs.
