July 2026. By day, I consult on AWS for financial-services clients — mostly architecture and delivery work for teams under real regulatory constraints. Nights and weekends, I’m building a self-hosted, mostly-Go lab for AI-agent development, and studying how to make agents reviewable and trustworthy once they’re doing real work: evals that mean something, independent review with real structural distance between the builder and the thing that checks it, and operational patterns for running agents day to day instead of just demoing them. I’m also getting back into conference speaking, after a long gap away from it.

About

Mon, 01 Jan 0001 00:00:00 +0000

I’m a software engineer with over 30 years in the field, the last 20 of them in financial services technology and the last 10 focused on AWS. I’m currently a Principal Consultant at Vertical Relevance, an AWS-focused consulting firm. Before that I co-founded and was CTO of CoinLion, a crypto-trading startup out of Sioux Falls, South Dakota (2017-2018 era). I’m based in Sioux Falls.

I spent a good chunk of the 2000s and early 2010s as a Drupal contributor — maintaining a handful of modules (Views Simple Spy, Acronyms, Feedme XML, AMQP, Bootstrap - Combined) and making the rounds at DrupalCampLA 2008, DrupalCon DC 2009, and DrupalCon Denver 2012. I’ve used the GitHub handle dellintosh since 2010.
