Multi-Agent RAG AI Assistant — architected a LangGraph-based multi-agent system in 20 days with Pinecone vector search + MySQL hybrid retrieval, delivering context-aware responses across 25+ relational data models.
Token-by-token streaming UIpowered by Vercel AI SDK with OpenAI & Gemini LLMs — orchestrating agent handoffs and tool calls via LangGraph StateGraph with real-time SSE delivery to the client.
Reddit Market Intelligence Pipeline — built a live scraper (Cheerio) + LLM extraction layer that identifies structured SaaS opportunities from subreddit data and surfaces them in a ranked dashboard.
Crunchbase Intelligence— zero-latency SSR querying of Crunchbase's organization graph via API, enabling real-time startup discovery with server-side data freshness guarantees.
Stripe Monetization & Creator Economy — integrated Stripe API + Webhooks for subscription tiers, premium content gating on AI-powered blogs, and idempotent payment event handling via webhook signatures.
Multi-tenant App Router architecture — RSC streaming + nested layouts + route-level code-splitting reducing TTFB by ~40%; Upstash Redis sliding-window rate limiting protecting all API routes.
Social Hub with Sub-Devs — Reddit-style nested threaded discussions with rich-text editor, unified feed ranking algorithm, and LaunchPad for product launches with trending metrics.
Observability & Auth — PostHog event analytics for funnel tracking, NextAuth.js with OAuth + credential providers, HTTP-only cookie sessions, and CSRF protection covering OWASP Top 10 vectors.
