HI, I'M CHANDAN
$ FULL STACK AI DEVELOPER
building multi-agent AI systems, scalable
microservices, and enterprise web apps.
currently Full Stack AI Developer @ Variabl, Bengaluru
multi-agent systems — what I build
one orchestrator, many specialist agents. it routes every job to the right one.
$ cat ~/about.txt

Nearly 3 years shipping production systems across 5 companies — multi-agent AI assistants, gRPC microservices, Stripe marketplace billing, and AI news-intelligence pipelines. I like systems that survive real traffic — a 500k-request raid included. Always open to hard problems.

┌─Variabl logoVariabl/Full Stack AI Developer[LIVE]
│Feb 2026 - Present | Bengaluru / In-office
  • │›Architected a multi-agent AI assistant on Google ADK — an orchestrator routing to 15+ specialist agents (invoicing, payments, GST, income, treasury, tax) with real function tool-calling, human-in-the-loop confirmations, and generative-UI cards streamed over a first-party SSE/AG-UI pipeline.
  • │›Engineered end-to-end GST compliance and automated filing, including in-chat GSTR filing as a code-driven state machine with secure GCS document storage and admin review APIs.
  • │›Shipped a multi-channel notifications microservice — webhook handling with signature verification, daily quota enforcement, and month-end reminder nudges. Integrated YouTube, Zerodha Kite (MCP), and Google Calendar via OAuth.
