ABOUT ME

Experienced Ruby on Rails and Python Developer who loves teaching

I'm an experienced and friendly Ruby on Rails developer. Before I was a programmer I was a Maths tutor. I've mentored colleagues before, taught programming to newcomers and ran workshops for developers that have got rave reviews.

In summary, I love programming and I love teaching!

Over the years I've built and maintained lots of Rails apps. Just a few examples: Arnold Clark * Helped to build a Rails app for car service booking system in 6 weeks (https://www.arnoldclark.com/servicing/book) resulting in a 350% increase in bookings * Helped rebuild Arnold Clark's flagship site (https://www.arnoldclark.com) with Rails and React.js - 1 million uniques a month * Built an internal Rails app for automating advertising for that currently saves around £100K a year Growth for Small Business * Built a Rails app dashboard tool for MerchantAds (https://www.merchantads.com/) giving a 4 hour a week time saving - a SaaS app is in the works! * Rebuilt a Wordpress app (https://www.dytapro.com) in Rails (https://www.talkgdpr.com) using Heroku, TDD, Devise, Bootstrap and Stripe (soon to be launched) List of Things for Sale * My first Rails app - the world's simplest ecommerce site that got to number 1 on Hacker News and got 36,000 uniques in the first 24 hours All these things have been built with TDD, CI and Agile methodologies. I'm a stickler for code quality so I've spent many years improving my refactoring techniques.
