Work experience

Head of Core Engineering, Attest Technologies (London, GB), January 2016 - Present

Developing a a super powerful, real-time consumer insights platform.

Java/Scala Team Lead, OVO Energy (London, GB), October 2014 - November 2015

  • PAYG+: led the development of PAYG+—the first product in the UK enabling pre-pay energy customers to top up their utility meters online. The product was featured in Wired UK, The Sun and Tech News Europe, was placed at the centre of OVO's spring advertising campaign, and since launching in January 2015 has acquired over 25k customers in 10 months. Winner of 'Mobile Innovation' and 'Pioneering Tech' at New Thinking Awards 2016
  • Onboarding Timeline: led the development of a product that supports PAYG customers in the 4-10 weeks period before the energy supply starts. The product saved money by reducing propensity to contact and operations overhead and reduced brand damage given the improved user experience. Part of the logic is now being adopted by 3 other teams.
  • Smart Meter Booking: most recently led the development of OVO's smart meter booking product, preventing 35% of customers from signing up for a product they actually can't have and allowing the remaining 65% to manage their smart meter installation appointment online instead of having someone in operation call each one of the new customers.

Lead a team composed of a total of 6 developers Designed systems architecture consisting of 7 microservices Introduced processes and standards to ensure team consistently delivered high-quality software Implemented different types of tools to ensure service management could monitor systems, get accidents alerts and do some basic troubleshooting in case of accidents Developed RESTful Scala web services with Spray Front end development in AngularJS 1 Data persistence in NoSQL database (MongoDB) Caching in Redis Test Driven Development Continuous deployment with Go CD and configuration management with Chef
