About me

Intro

I am an AI Solutions Architect with 9+ years of experience, but my core skill is translation: I translate complex business goals into scalable, intelligent systems. Currently, I bridge the gap between Agentic AI and real-world operations at Constient Global Solutions. My focus is on moving Generative AI from "proof of concept" to production. Most recently, I architected a Multi-Agent Cash Reconciliation System using LangGraph and OpenAI that achieves 98% reconciliation accuracy with 100% financial precision—solving a critical enterprise pain point by balancing autonomous agents with Human-in-the-Loop workflows. My technical foundation was solidified at Amazon (Luxembourg), where I engineered data pipelines that increased customs audit coverage from <1% to 99%, and through my MSc in AI for Business Transformation at SKEMA Business School. I don’t just build systems; I empower the people using them. From training 3000+ professionals in robotics and IoT to leading engineering teams through the full SDLC, I believe scalable technology requires scalable teams. Core Competencies: Architecture: Agentic AI, RAG Pipelines, Human-in-the-Loop (HITL), Microservices. Tech Stack: OpenAI GPT-4o, LangGraph, LangChain, FastAPI, Python, AWS, PostgreSQL. Business Impact: Agile Project Management, Stakeholder Management, Digital Transformation.
