About

Full-Stack Systems Engineer and Agentic AI Architect building autonomous multi-agent pipelines, sub-second real-time Voice AI, and high-precision semantic retrieval systems. Core rule: Determinism where possible, AI where necessary. I build distributed infrastructure, relational vector schemas, and event-driven worker queues first, deploying LLMs for structured reasoning, tool orchestration, and zero-hallucination contextual synthesis. Verified Impact & Highlights: - 2x Hackathon Winner: Built and shipped production-grade AI systems under strict competitive constraints (including FreshGuard / SIH post-harvest agricultural intelligence). - 200+ LeetCode Solved: Strong foundation in data structures, graph algorithms, dynamic programming, and computational complexity. - 5+ Production AI & Voice Agents: Engineered sub-second voice-to-voice streaming (LiveKit + Cartesia), CrewAI multi-agent crews, and LiteLLM budget circuit breakers. - High-Throughput Distributed Mesh: Architected BullMQ + Redis worker clusters processing 10,000+ records/day with SHA-256 deduplication and PostGIS spatial routing. Core Systems Built: - CareerRizz: Multi-agent career platform with ATS ingestion (Greenhouse, Lever, Ashby), 1024-dim pgvector matching, and policy safety gates. - NoCap AI: Sub-second voice-to-voice RAG assistant connecting AssemblyAI STT, LlamaIndex retrieval, and Cartesia TTS with Silero VAD turn-taking. - Snatched.ai: Codebase intelligence engine using 512-token sliding windows (tiktoken), ChromaDB HNSW indexing, and SQLite traceability. - ResearchX: Agentic RAG microservice on LitServe and CrewAI executing concurrent StackExchange and live web research on Groq LPUs. - The Farmer Market (FreshGuard): Post-harvest biological decay physics engine (Q10 kinetics), ethylene tracking, and PostGIS spatial salvage. - GrowCus: Student growth OS with an academic risk engine, Redis caching, and Groq Aria AI guidance. Technical Stack: - AI & Vectors: LiveKit 1.8+, LlamaIndex, pgvector, ChromaDB, Voyage AI, CrewAI, LitServe, Groq, Ollama, Gemini 2.5, Claude 3.7 - Backend: Fastify, Express, Node.js, Python, PostgreSQL, PostGIS, TimescaleDB, Supabase, MongoDB Atlas, BullMQ, Redis - Frontend: React 19, Next.js 16, TypeScript, Vite, Tailwind v4, Radix UI, React Native (Expo) - DevOps: Docker, Turborepo, pnpm, Playwright, GitHub Actions Open to collaborating on distributed systems, multi-agent frameworks, and AI infrastructure.
