What I'm looking for

I'm looking to lead advanced AI, LLM/RAG, and distributed-systems initiatives where I can improve engineering operations, build reliable platforms, and mentor technical teams.

At Dell Technologies, I lead advanced engineering solutions that optimize internal tools and deliver high-impact AI agent systems. I build RAG systems that ground LLMs in internal knowledge and improve response accuracy and relevance.

I design stateful multi-agent workflows in Python and LangGraph, apply prompt engineering, and use machine learning for predictive internal-tooling improvements. My backend work includes C#, SQL Server, Redis, and RabbitMQ for resilient, high-performance distributed services.

Previously, I strengthened reliability at CI&T through SLOs, error budgets, GitOps, ArgoCD, New Relic, and CI/CD automation. Over more than a decade at Actminds, I led multiple teams and delivered microservices, full-stack applications, and DevOps workflows across diverse client sectors.
