AI-powered financial planning for India

Built for Indian salaried professionals who have no idea if they're on track for retirement. FUMONEY turns messy financial inputs into a personalized Financial Fitness Score, retirement corpus projections, and real-time what-if simulations.

Hard engineering problems solved:

• Designed a goal-based planning engine that models compound growth, inflation-adjusted returns, and multiple simultaneous financial goals without state explosion
• Built real-time simulation system with debounced recalculation to stay responsive under rapid user input
• Auth + RLS via Supabase to ensure zero cross-user data leakage at the DB level

Build production-ready AI agent systems

An open-source learning platform teaching developers to build stateful, scalable AI agents — not toy demos. Covers LangChain, RAG pipelines, LangGraph orchestration, and Model Context Protocol with real deployment patterns.

Hard engineering problems solved:

• Architected a multi-agent orchestration layer using LangGraph where agents hand off tasks with typed state — no spaghetti tool-calling chains
• Implemented hybrid retrieval (semantic + BM25 keyword) for RAG to handle both conceptual and exact-match queries without two separate pipelines
• Designed MCP server integration patterns that work across local and cloud-hosted agent deployments

Ship real products over a weekend

A marketplace where startups post bounty projects and builders collaborate in-person to ship working products in 2–3 days. Handles project listings, builder profiles, team formation, and bounty payouts.

Hard engineering problems solved:

• Built optimistic UI updates with server-state sync so builders see changes instantly without stale cache issues during fast-paced weekend sprints
• Designed a matching algorithm that pairs builder skill profiles to project requirements without requiring explicit skill tagging by either party

Enterprise banking @ Wells Fargo

Frontend architecture for the system managing 10,000+ banking policies across Wells Fargo's core workflows — used daily by compliance, legal, and operations teams.

Hard engineering problems solved:

• Led migration of critical policy rendering pipeline from legacy AngularJS patterns to a component architecture that cut load time significantly and eliminated an entire class of rendering bugs
• Built a shared state management layer that synchronizes policy lifecycle state across 6+ concurrent user roles without race conditions
• Drove 1000+ production contributions — features, defect fixes, performance optimizations — with zero P0 incidents
