PROJECTS
- Built a custom AI agent that autonomously tracks orders and processes refunds through multi-step reasoning, without using LangChain or any agent framework.
- Designed a Zod-validated tool registry that validates every LLM response against strict schemas before any database write or external API call — preventing prompt injection and hallucinated actions.
- Implemented failover routing across LLM providers (Llama 3.3-70B → Llama 3.1-8B) so the system keeps working even when the primary provider hits rate limits.
- Built a RAG chatbot that answers questions over PDF documents using hybrid retrieval (vector + keyword search) with an anti-hallucination guard — it refuses to answer when it can't find reliable evidence in the documents.
- Implemented real-time streaming via Server-Sent Events so answers appear token-by-token, and a zero-cost infrastructure stack (Render + Supabase + Upstash + Groq + Gemini free tiers).
- Built a symptom triage system that routes patients to the right medical specialist based on reported symptoms.
- Developed browser-based video consultations using Vonage WebRTC with no app download required, and a credit wallet system with full audit trails for purchases and refunds.
