Tech consulting and software development.



AMJ helped Tumplate develop plugins for Airtable, Google Sheets and Google Chrome. Gavin was able to understand our product very rapidly; allowing him to start building straight away. We adopted a fast, lean approach to turn out some great apps in no time at all.

Recently I had the pleasure of collaborating with AMJ on a freelance project. Gavin's motivated, can-do attitude makes him easy to work with. He's a great team player and has fantastic attention to detail. I wouldn't hesitate to recommend Gavin's services for freelance back-end development (hopefully we can work together again soon!).

I needed a particular Shopify app for Funky Moose Records, and a mutual friend referred me to AMJ. Gavin understood the assignment in the first meeting and was great at putting it into action with some recommendations along the way. We're already thinking of future projects we can work on with him.
