June 2024 - Present
• Led multi-agent system using LangGraph with domain-specific workflow nodes, reducing p95 latency 65% (8.2s → 2.9s)
• Owned Model Context Protocol (MCP) server for AI/ML integration with JWT auth, achieving 95% intent classification accuracy; mentored 2 junior engineers
• Designed production RAG pipeline with Azure AI Search and PyMuPDF, cutting processing time 40% and improving data accuracy
• Drove multi-intent query architecture with structured outputs; adopted as standard for 3 product teams
• Reduced hallucinations 36% (28% → 18%) by routing ops to deterministic tools; built LLM eval framework establishing team-wide standards
• Cut Azure OpenAI costs 32% ($18K/month savings) via tiktoken compression and intelligent routing

AIDraft – AI-Powered Architectural Design Platform

Featured

Built AI-powered platform that generates 3D architectural models from text descriptions, sketches, and photos. Uses multi-agent system with Azure OpenAI (GPT-4) orchestrating three specialized agents: Interpreter Agent (analyzes input), Designer Agent (creates design), and Renderer Agent (generates 3D model). Integrated Azure Computer Vision for sketch and photo analysis, with Three.js for interactive 3D visualization.

AI Engineering Philosophy

How I Build AI Systems

Core principles and what makes me different

Reliability > raw model intelligence

A mediocre model with strong guardrails beats a brilliant model that hallucinates.

Implementation Flow

Validate at inference time, not post-processing. Use structured outputs with schema enforcement. Implement multi-layer validation: input sanitization → model guardrails → output verification.
