Cover image for VisiHealth AI – Explainable Medical
VisiHealth AI – Explainable Medical VQA VisiHealth AI is a multimodal, explainable Medical Visual Question Answering system designed to analyze complex clinical radiology scans. Utilizing PyTorch, ResNet-50, and BioLinkBERT, the platform fuses text and spatial image patches through a real multi-token cross-attention mechanism to provide accurate clinical insights. It builds diagnostic trust through explainable AI by overlaying attention-map heatmaps on original scans and deriving human-readable rationales from a 4,444-triplet medical knowledge graph. Delivered via a scalable Next.js and Flask architecture, it demonstrates my capability in deep learning and healthcare AI integrations

Cover image for NexusAI — Enterprise Agentic Assistant NexusAI
NexusAI — Enterprise Agentic Assistant NexusAI is a production-ready enterprise agentic conversational platform that revolutionizes e-commerce through intelligent intent classification and semantic product search. Built with LangGraph, FastAPI, and Next.js 15, this AI assistant utilizes advanced RAG pipelines and Supabase pgvector to deliver highly personalized, context-aware recommendations in real-time. By leveraging Groq's LPU for sub-second LLM inference and FlashRank for cross-encoder analysis, the system ensures unparalleled accuracy and speed. This project highlights my advanced proficiency in LLM orchestration, vector databases, and real-time frontend integration via Server-Sent Events.

Cover image for 🚀 Case Study: Production-Grade Autonomous
🚀 Case Study: Production-Grade Autonomous Lead Gen Basic Zapier flows and fragile prompt chains break as soon as you scale. I recently replaced a client’s brittle setup with a stateful, type-safe Multi-Agent system that autonomously prospects, scores, and drafts outreach for B2B leads. ⚙️ The Stack: LangGraph + PydanticAI + MCP (Model Context Protocol) + Claude 3.5 Sonnet ⚡ How It Works: Stateful Orchestration (LangGraph): Manages execution with automatic checkpoints—if an external API fails, the workflow resumes without losing context. Type-Safe Agents (PydanticAI): Enforces strict data schemas so outputs never hallucinate or break downstream code. Native Integrations (MCP): Direct, secure read/write access to internal CRMs without messy webhooks. 📈 The ROI: 40+ hours/week saved on manual research and lead scoring. 100% data accuracy (zero JSON parsing errors). Human-in-the-loop gating for final outreach approval. 💡 Need resilient, enterprise-ready AI infrastructure for your business? Check out my profile to book a Technical Audit & AI Automation Blueprint.
