I love collaborating, so check out my list of open ideas.
I once made a cell phone out of resistors, capacitors, walnut, and leather.

Please get in touch!
I love to hear from people, especially if I can help with their projects or careers! Please email me if you:
- are interested in collaborating (check out my list of open ideas)
- want more details about any of my projects (tech implementation, business strategy, etc.)
- would like an introduction to someone (e.g. visualization/statistics, functional programming, or software design experts; investors in those domains)
- want feedback on something you’re making
If you think it’s weird to email people you don’t know — it’s not! Some of the best relationships I have, business and personal, started when one of us reached out to the other for help on a project, thoughts on a problem, or just coffee! So, if you’re considering emailing, please do it!
For best results, see Patrick McKenzie’s tips for emailing busy people.
