This portfolio is a sample my consulting work with Ruby on Rails software development.

The majority of my time is spent on my own Shopify apps now instead of consulting but this page is left for future reference.

Selected projects

Open Source Contributions

I enjoy contributing to various Open Source software projects. Due to my experience, most of the contributions are to web based software.

A/B Split Test Calculator

A/B testing is a major part of conversion optimization. But not every system supports it so A/B test data has to be collected and checked manually. This A/B split test calculator was developed for that.

Dripify Shopify App

Safely, easily, (and finally!) get Drip working on your Shopify site.

Redmine Budget Plugin

Redmine Budget was a project sponsored by Shane and Peter Inc to solve a problem they were having. They found it was difficult to connect different client deliverables with tasks in Redmine. This made estimation and progress tracking difficult and time consuming. Their larger projects just moving too fast to make sure they were staying in the budget.


Redmine is an Open Source project management web application. Written using Ruby on Rails framework, it is cross-platform and cross-database. I joined the Redmine core team in August 2008 and have been actively contributing and supporting the project.
