What I Do

Technical Architecture

As an architect I gather and analyze product requirements and turn them into system components, a blueprint for the engineering of the product. This can include making decisions on the technology stack, software design patterns, and cloud deployment strategies. Every decision has tradeoffs and I've learned to enjoy and thrive in the ambiguity.

Engineering Leadership

I've managed cross functional development teams, serving as a scrum master. I've also managed software engineers, both directly and indirectly. I enjoy being able to make decisions for a team and setting the technical direction. I love being able to mentor people and teams, seeing their expertise grow and creating better products.

Software Engineering

I love building things. Building a web app from scratch and finally seeing your data brings a great sense of joy. It's fun tinkering with the minute details of visual design in order to look just right. I love exploring new technologies and thinking about how they may fit into the overall system. Ultimately putting it into the hands of customers, learning from their experiences, and refining the product lead to truly feeling accomplished.
