Values
I believe that:
- diversity and inclusion are crucial and create rich, healthy, sustainable, productive organizations.
- DRY and the Rule of Three apply to docs just as much as code.
- people can only do great work if they are healthy, growing, supported, and respected.
- all great processes have one thing in common: they are regularly reviewed and refined.
- the most important aspect of any technology is its potential to solve problems.
- technology is a phenomenally powerful tool that we humans have at our disposal to solve problems — if we so choose.
- we do some of our best thinking in collaboration with others.
- institutional/communal memory is critical to building sustainable organizations.

- I created a diagram of the overall architecture of the “Reuters Next” platform
- I was asked to review a draft of the API spec; I provided these notes
- I developed a document to capture the culture and process of my team, so we could ramp new members up quickly and effectively
- I determined that the API codebase I had inherited needed to be refactored, and wrote this summary to explain why
- When I left the project I shared my parting thoughts with the team
- I sometimes perform technical audits of existing applications or platforms. Here’s one example; I can provide more extensive examples upon request.
I’d be happy provide more examples of my work, such as architecture diagrams and presentations, business analysis, code, etc. Please get in touch!
