  • Responsible for bug fixing, refactoring/rewriting code, new feature dev, new web service dev, tooling and automation, devops, operations, database management, and supporting customers to solve their issues and elicit feedback, requirements, and new directions to take our team in.
  • Built a firewall deployment automation tool that spread and became used by most teams in EC2 and pushed hard to find the root cause of a service issue that led to discovering new customer usage patterns and feature requirements that fed back into the team’s roadmap.
  • Gained extensive experience here in Ruby, Rails, general web service/API development, building scalable web services, operating and supporting web services at scale with hundreds of servers and database configurations, and focusing on creating a great experience for our customers.
  • Started a new team/project - a web app for project management and roadmap planning that would be used by all teams and management in EC2.
  • Technical lead on this project, responsible for all technical design/technology/architecture, for working with our potential users to come up with and implement a design for the app that would solve their problems, for the team’s software engineering methodologies, and for much of the user interface and user experience of the app.
  • Grew and trained the team up to four people and developed an app that all management in Cape Town got on board with. Many roadmap-related problems that they had been having were solved by the app, and their planning processes became much more efficient and effective.

Internal Orchestration System

This is a system of web applications and services that visualizes and orchestrates Amazon's full fleet of hardware around the world, and all activity/virtual machines running on that hardware. It is a massive Rails app with hundreds of synchronized databases that I helped develop, build out, and maintain. I also supported it through many issues and changes. (Not publicly available)

Project and Roadmap Management Tool

This is an internal project/roadmap management application for Amazon Web Services. I was the technical lead on this, and our database dealt with people in the organization, their different roles, teams and how they were related through projects. We built an Ember.js front end app, a rails back-end, and some MySQL servers for the database. It also has reporting/analysis capabilities. (Not publicly available)


A small events and social application for an organization in South Africa. It is written in JavaScript with Ember.js, and Parse for the back-end.
