Pandidharan Gopiraj

I've built AI-native platforms including JobHunt AI, a self-hostable job hunting system that automates discovery, resume tailoring, application tracking, and networking through autonomous agents.

I designed multi-agent and RAG architectures with LangGraph, FastAPI, React, Qdrant, Redis, Ollama, FAISS, Hugging Face, and Docker. My self-reflective RAG platform uses retrieval-confidence validation, cosine similarity scoring, adaptive context expansion, and risk-based query interception to reduce hallucinations before LLM inference.

I've also delivered an AI-powered loan eligibility and risk scoring system, achieving approximately 0.75 ROC-AUC while using SHAP to address explainability, bias, and compliance requirements.

As a freelance software developer, I translate stakeholder requirements into deployable web and AI systems under short delivery cycles. I bring end-to-end system thinking across LLM integration, REST APIs, microservices, containerized deployment, CI/CD, and secure self-hosted infrastructure.
