I’m a Rubyist of 12+ years, primarily acting as a senior developer and running operations for Noko (Freckle) Time Tracking. I specialize in maintaining and refactoring legacy applications; fixing up existing code to take advantage of the meteoric jumps of modern, evergreen browsers.

Hey Everyone, I have began building websites in the mid 90s as a kid, and transitioned to building web applications using ColdFusion. I began messing around with Rails in 2008, and fully migrated to it in 2012. Outside of Rails I have extensive experience with Javascript for both front and back end. Over the years I've worked with a majority of front-end frameworks including React, Vue, Svelete, Stimulus, Turbo, and Backbone. At this point in my development career I'm mostly interested in building scalable systems and utilizing various web3 technologies.

Full Stack, Senior Software Engineer. I've been working with Rails since 1.0! I've used Rails + dynamic javascript (react, vue, jquery, prototype!) at startups of various sizes. Open source contributor - maintainer of Mongomapper + fakefs; wrote the first node.js debugger, contributed early on to RSpec; (probably?) helped inspire FactoryGirl via my own factory solution - fixture_replacement. I've also contributed to a ton of other open source projects. I've also worked along side some of the best in the industry in small startups - people who built FB, Hulu, MS, Google. I'm also wickedly creative and awesomely humble.

Hello! 👋 I'm a driven software engineer from the Pacific Northwest. I've been writing rails apps for 5+ years in a professional capacity in industries including e-commerce, cybersecurity, e-learning, and house project management. I got my start at a local bootcamp called Epicodus where I spent 40-60 hours a week for 9 months studying rails and various javascript frameworks (and bicycle couriering to pay the bills!). Most recently I was working with a local e-commerce startup called Dutchie on their Partner Integrations team. Here I helped design and implement a long-standing initiative to upgrade our Hubspot integration so that customers could leverage our data for targeted promotions. I also helped to design and implement an improved customer matching scheme with an acquired partner POS. This feature will improve the checkout experience for thousands of customers. I consider myself a great collaborator, a committed mentor and a pragmatic programmer who enjoys writing idiomatic ruby. These skills make me a great addition to any team, and I look forward to speaking with you about your project. 😊
