// Sr. Staff Engineer · Cloud Architect · Data Infrastructure

Senior Staff Engineer with 10+ years building large-scale data infrastructure across healthcare, fintech, banking, and insurance. I specialize in cloud architecture, ETL systems, and contact center platforms — with a focus on delivering outcomes that actually move the needle, not just shipping code.

Beyond the technical work, I'm invested in growing engineering teams — mentoring engineers, raising the bar on architectural thinking, and helping organizations make better decisions with their data. Research and continuous learning are non-negotiable parts of how I operate.

This site is where I write about the work: deep dives into AWS and multi-cloud architecture, IaC patterns, data engineering at scale, and whatever I'm actively researching or building. If something took me time to figure out, it probably belongs here.
