Principal Architect | Enterprise Modernization | AWS Solutions Architect Professional

Strategic technology leader and trusted advisor with a track record of modernizing regulated, mission-critical platforms at scale. I specialize in aligning business strategy with technology execution through multi-year transformation roadmaps, governance frameworks, and scalable architecture patterns.

My current focus is the industrialization of AI: moving LLM implementations from experimental "wrappers" to governed, deterministic, and cost-efficient enterprise ecosystems.

A reference implementation for high-reliability RAG (Retrieval-Augmented Generation) using LangGraph and Gemini 2.0 Flash.

• Design Pattern: Implemented as a State Machine to ensure deterministic flow control solving the "black box" unpredictability of standard RAG.
• Self-Correction Logic: Employs an automated Relevance Grader to audit retrieval sets against user intent, triggering fallback loops when confidence thresholds are not met.
• Infrastructure Resilience: Architected to be LLM-agnostic; successfully implemented a seamless migration from OpenAI to Google Gemini to optimize for FinOps and API availability.

• Cloud Architecture: AWS Professional certification, EKS, Serverless, and Cloud-Native refactoring.
• Distributed Systems: High-throughput event-driven design using Apache Kafka and Java/Spring Boot.
• Enterprise Governance: Tech roadmapping for ROI, FinOps-led cost management, and DevSecOps.
• AI Orchestration: LangChain/LangGraph, Vector Database optimization (ChromaDB), and Prompt Engineering.

"I bridge the gap between C-suite vision and engineering execution, ensuring that emerging technologies like AI/LLMs serve as drivers of measurable business value rather than sources of technical debt."
