I'm a software engineer with 3+ years of production experience shipping scalable backend systems — multi-tenant SaaS platforms, payment integrations processing ₹1 Cr+ monthly, and cron-based orchestration handling 10k+ tasks/day. I work primarily in TypeScript, Node.js, and React, with deep experience in PostgreSQL, Redis, and AWS.
Right now I'm transitioning into AI Agent Engineering — applying my backend and multi-tenancy chops to building reliable, production-grade LLM systems. I'm doing this in public.
An open-source, multi-tenant AI support agent — think self-hostable Intercom Fin / Sierra for SaaS companies. Built to explore production-grade agent engineering concepts end-to-end.
Stack: TypeScript · Next.js · Mastra · Vercel AI SDK · PostgreSQL + pgvector · Upstash Redis · Langfuse · Gemini / Claude / Llama
What it tackles:
- 🔁 Agent loops with tool-calling and structured outputs
- 🧠 Layered memory systems (working, short-term, semantic)
- 🏢 Per-tenant prompts, tools, and knowledge isolation
- 📊 Evaluation harness with golden datasets + LLM-as-judge
- 🔍 Full observability with trace hierarchies and cost attribution
- 🛡️ Prompt injection defense and human handoff patterns
