Leif Gensert - @leifg

Full time developer since 2008. Started freelancing in 2016. Full time employed again since November 2020 at TriumphPay. Building event sourced systems with Ruby.

I contribute to Open Source and implemented a Live Salesforce Formula Evaluator with open sourced frontend and backend. Over the years, I gave various talks on local user groups and coached at Rails Girls workshops in Munich, Paris and Barcelona.

I have strong opinion on blockchain

In my free time I mostly just enjoy my life in Southern California, go on hikes and sometimes I run.
