Background

Enterprise-scale expertise,
startup flexibility.

With 20+ years in data engineering and cloud architecture, we have built and led data systems that operate at a scale most engineers never encounter. Our experience at Mastercard (Brighterion) included hands-on ownership of infrastructure processing over 160 billion transactions annually.

We don't just architect — we execute end-to-end. From writing the first pipeline to deploying production systems across four global regions, we own the full lifecycle. Working in lean teams, we have consistently delivered complex systems on time, under pressure, and at enterprise quality.

Through Sun AI and Data LLC, our principal leads every engagement and brings in highly skilled engineers based on your specific needs — serving as a true one-stop shop: data platforms, AI agents, cloud infrastructure, and ongoing data management, all under one roof.
