The Tab was a VC backed start-up that aspired to be the world's largest platform for young journalists. I joined as part of a funding round from one of Europe's top VCs to build a team that leveraged technology to continue to drive their growth.I built a tightly integrated high performing team which consistently delivered features that supported growth. Utilising AWS we built multiple services utilising Node.js alongside SQS, API Gateway, Elastic Beanstalk, Lambda and Cloudwatch. Services were fully tested and automatically deployed to auto scaled environments. New Relic, Runscope and Pagerduty alerting and monitoring ensured a fast response to any issues.The development process used a mix of research, wireframes, mock-ups plus prototyping of both designs and architecture. Our goal was delivering a minimum viable product and scaling from fast feedback. We used segment.io to federate all of our events to Mixpanel and Intercom which enabled data driven decision making.We built a large data warehouse which contained data from Google, Facebook and WordPress. Processing millions of rows a day and transforming them into actionable insights for our leadership and authors.

I was hired to create a development team within Metro as previously IT had been a slow moving centralised DMGT group function. My main goals were to put development at the heart of the business and promote lean thinking.I re-platformed metro.co.uk from a bespoke CMS to the WordPress VIP platform on time and under budget during 2012. Leading the team that developed the responsively designed web app that drives metro.co.uk, which was a core component of its 350% growth.Initially using SCRUM we then moved to Kanban combined with Lean Startup principles to streamline workflows and make the majority of product decisions based on data. This combined with an automated deployment and test environment allowed us to release almost everyday.I was also instrumental in shaping the technology decisions for the internal startup Metro Play (sold to 666 Bet), which was a incorporated standalone gaming business within DMGT. I created their development process and hired an additional team and then ensured they delivered against their revenue goals.

Enron Energy Services (EES) was a business unit of Enron Corporation, whose purpose was to provide gas, electricity, and energy management directly to businesses and homes. Enron Energy Services signed contracts with large commercial and industrial customers guaranteeing a fixed amount of energy savings off their historical bills. Enron contracted to share the savings, split installation costs and/or assumed they could exceed these savings and pocket the additional savings for themselves.I worked for EES as a data analyst and streamlined their procurement spreadsheets using a mixture of advanced formulae and VBA. Left to go to university just before it went bust.
