Created a remote hiring process and working environment that created an integrated team which is mix of onsite and remote. Remote working enabled us to add some great developers to the team and improved retention by 250%.Created a technical strategy to support Reevoo's mission and goals over the coming years, gradually extracting functionality from our monolith to a set of loosely coupled micro services connected asynchronously (AWS, Kubernetes, Docker, RabbitMQ, Ruby, Rails, React, Elastic search, Postgres).Successfully led the companies ISO 27001 certification, working across the company to build an Information Security Management System that covered all departments.Designed data warehouse to provide responsive and consistent data visualisations both internally and to our clients. Additionally, it was important to decouple reporting from the schema of our transactional database (Redshift, Python, Luigi, Ruby, Postgres, Kimball Dimensional Modelling).

Designed and built a REST API allowing clients to get more value from the data we collect and design their own display solutions (Ruby, Grape, Swagger, MySQL).Created an internal health dashboard to reflect business metrics and provide early warning of system issues (Ruby, Rails).Implemented review moderation application used by Reevoo’s internal moderators to publish or reject reviews (Ruby, Rails, JavaScript).

RocketSports (http://rocketsports.co.uk) was an online platform to help people access sports at a grass roots/amateur level and manage sports teams, events, clubs and leagues.The application ran on Rails 3.2 and Ruby 1.9.2 and used Devise, Cancan and Omniauth for authentication / authorisation, Draper and Cells to simplify the views, and ActiveAdmin to provide an administration interface.Tests were written in Cucumber and Rspec.The application was created working in collaboration with the designer on the site design, layout and user journey.The designer supplied HTML and PSD files and one global.css file which where translated to HAML and SASS using Compass and the Blueprint grid.jQuery, CoffeeScript, and AJAX were used on the front end for client-side validation, auto completion of fields and generally making the user experience smoother.A previous version of the application had been developed by a number of different developers at different times with no continuity, leading to a fragmented codebase where much of the code’s intent was not clear and large areas of code and tests were commented out. After an initial spike to judge the viability of rewrite the code was completely rewritten, reaching a similar level of functionality after around twelve weeks.
