Hey, I'm Andy.

A data professional living in Vancouver, BC, I graduated from Simon Fraser University with a bachelor's degree in Statistics. My career has taken me from data analytics to Kubernetes administration and into data engineering, where the focus is on data warehouses and building Text to SQL Business Intelligence Agents. Outside of work, I build full-stack systems to continuously improve my ability to design, deploy, and scale systems end to end.

This portfolio is a collection of the niche problems, experiments, and architectural choices that shape the systems I build.

A second brain to help you shape software decisions

If you’re working on something and want a second brain before committing to a build, I’m happy to talk it through. I work directly with you to clarify the idea, pressure-test the approach, and make practical technical decisions that won’t box you in later.

I stay hands on and take responsibility for the outcome, because what we build reflects on both of us. Every project is handled directly with care, clear communication, and a focus on long term maintainability.
