I build production-grade APIs, AI-powered systems, and cloud infrastructure that scale under pressure — from LLM orchestration pipelines to high-throughput Kubernetes platforms. If it runs in prod, it's my responsibility.

// about

The engineer who owns the outcome.

I'm a Backend, DevOps, and AI Systems Engineer who builds the stuff that has to work — the APIs, the pipelines, the infra, and increasingly, the AI layer on top of it. Not because it's cool, but because teams depend on it being up, fast, and correct.

My work spans production-ready Node.js/TypeScript APIs with event-driven architecture, to Kubernetes platforms running 8+ microservices, to RAG pipelines and LLM orchestration systems built on Azure OpenAI. I hold the Azure AI Engineer Associate (2026) certification and apply it in real systems.

Before software, I spent two years at Sterling Bank processing 100+ daily transactions — which gave me something no bootcamp teaches: obsession with data integrity and zero tolerance for system failure.
