What I'm looking for

I'm looking to build operable, reliable SaaS platforms where pragmatic architecture, cloud efficiency, observability, and hands-on engineering matter. I value teams where I can improve infrastructure and delivery while contributing to application code and migrations.

At Kahunas, I led a DigitalOcean-to-AWS migration within four months, cutting annual infrastructure costs by about US$30,000 and reducing recurring production incidents from weekly to largely eliminated. I’m now helping build a multi-tenant Node.js/TanStack platform, its data and observability stack, and an AI-assisted client migration service.

Across Kahunas, Nathan Digital, JobsGlobal.com, and WebVision, I’ve moved from full-stack development into hands-on DevOps, site reliability, and platform engineering. I build operable cloud architecture, CI/CD, observability, and secure infrastructure while continuing to contribute application code when it matters.
