🚀 Projects

DevDocAI · LangGraph · FastAPI · Groq · Qdrant · PostgreSQL · MCP · Redis

Production multi-agent system that auto-generates and updates engineering documentation from GitHub codebases

  • Multi-agent LangGraph pipeline: AST parser → LLM doc generator → Brave researcher → HITL review → Qdrant publisher
  • GitHub OAuth + encrypted token storage + MCP server with 6 GitHub tools
  • Human-in-the-Loop checkpoint — devs approve docs before publish, HITL pause/resume via PostgreSQL checkpointing
  • PR merge webhook → auto re-triggers pipeline · Onboarding RAG chatbot over Cohere + Qdrant
  • LangSmith observability · Building in public — read the series

NewsMail · MERN · AWS ECS Fargate · Cloudflare WAF · Groq · Resend · Redux Toolkit

Production newsletter platform deployed on AWS with AI-generated content and bulk email dispatch

  • Deployed on AWS ECS Fargate with ECR, ALB path-based routing, and Cloudflare WAF — 99.9% uptime, zero server management overhead
  • GitHub Actions CI/CD (dev → main) with automated Docker builds and rolling deployments — manual deployment effort reduced ~100%
  • Groq-powered AI content generation with bulk email dispatch via Resend — verified 40–50 recipients/batch with admin dashboard
  • bcrypt hashing, two-tier rate limiting (auth + general), express-validator for NoSQL injection protection
  • AWS Secrets Manager for zero hardcoded credentials + Cheerio + Axios scraping pipeline with Excel.js export

Invoicer (v1) · Next.js · TypeScript · MongoDB · Razorpay · Redis · Docker · CI/CD
