Autonomous AI Data Analyst Platform & Multi-Agent Investigation Engine

Built a production-oriented autonomous AI data analyst platform that combines multi-agent orchestration, Text-to-SQL analytics, statistical analysis, cross-modal RAG, LLM routing, and automated executive reporting to investigate complex enterprise business questions.

Engineered an autonomous multi-agent analytics platform using Python, FastAPI, and LangGraph, orchestrating 8 specialized AI agents for zero-shot intent classification, Text-to-SQL generation, statistical anomaly detection, and cross-modal Vector RAG across 581,718+ (15m+ development) structured business records with sub-300ms pipeline latency.
Architected a fault-tolerant 4-tier LLM routing architecture spanning local Ollama (Llama 3.2), OpenAI GPT-4o-mini, Google Gemini, authenticated Hugging Face Spaces (Llama-3.2-3B), and offline rule-based fallbacks, dynamically routing analytical workloads across local, cloud, and offline inference paths.
Built an AST-validated Text-to-SQL pipeline with 100% read-only parse-tree enforcement, schema-aware query generation, and PostgreSQL/SQLite execution across 5 core business entities, enforcing database access guardrails for LLM-generated queries.
Developed a cross-modal RAG investigation engine linking quantitative SQL results with unstructured operational incident logs through hybrid vector retrieval, successfully connecting Causal Event IDs such as SC-2025-003 and PL-2025-001 with 100% Recall@5.
Implemented a Critic Fact Validation Agent that independently audits LLM-generated claims against raw database execution results and retrieved evidence, using bounded retry loops and evidence validation to reduce hallucinations and improve the reliability of final analytical responses.
Developed an automated executive deliverable compiler that transforms autonomous analytical findings into interactive Plotly.js visualizations, ReportLab PDF executive reports, and openpyxl Excel workbooks, delivering multi-format business intelligence directly through the analyst interface.
Established a 12-metric automated evaluation and observability framework tracking SQL accuracy, AST safety, RAG retrieval performance, hallucination detection, token usage, latency, and agent execution traces, achieving a 100% pass rate across defined target scenarios.
Built a full-stack ChatGPT-style analytics SPA using FastAPI, WebSockets, asynchronous streaming, persistent chat sessions, benchmark/history navigation, and interactive system architecture tracing, providing an end-to-end interface for autonomous enterprise data investigation and analysis.

Enterprise Multi-Agent RAG Platform

Built a production-oriented AI platform that combines multi-agent orchestration, enterprise knowledge retrieval, data analytics, and workflow automation to support complex business tasks.

Engineered and deployed a 12-layer Agentic AI, Multi-Agent RAG, and workflow automation platform using Python and FastAPI on Render, orchestrating specialized AI agents for hybrid retrieval across 15,000+ document chunks, AST-guarded Text-to-SQL analytics across 6 database schemas, structured tool/function calling, and enterprise REST API actions.
Improved overall RAGAS benchmark performance by 35.4% (0.5648 → 0.7650) through Multi-Query Expansion, Dense (FAISS) + Sparse (BM25) Hybrid Retrieval, and Reciprocal Rank Fusion (RRF) Reranking, driving +151.7% Context Recall and +83.3% Context Precision.
Engineered a cost-aware Dynamic LLM Routing and Agent Orchestration layer that analyzes task complexity and token volume to route requests across Claude, Gemini Flash/Pro, and GPT-4o, while implementing sub-millisecond (<1ms) semantic caching with FAISS vector similarity (≥0.92 cosine threshold) to reduce latency and inference costs.
Implemented AI safety and security guardrails including PII redaction, prompt-injection sanitization, AST-based SQL parse-tree validation enforcing read-only execution, schema allowlists, and an automated Validation Agent with claim verification and auto-retry loops to mitigate hallucinations and improve response reliability.
Architected end-to-end AI workflow automation and production observability incorporating AI-generated reports, ReportLab PDF compilation, structured tool/function calling, automated n8n workflows, SMTP notifications, conversation memory, state management, and OpenTelemetry distributed tracing for real-time agent execution monitoring.
