Mobile virtual network operator (MVNO) full-stack co-founding, development and operations on Amazon Web Services (AWS). The IT department was only 4 people who build the entire platform from the ground up. We worked as DevOps teams, heavily relying on automated surveillance provided by New Relic, AWS Beanstalk and Nagios. Our focus was to have the system be as self-reliant as possible and being able to self-recover in case of any breakdowns. If there was a breakdown that could not be automatically handled our team was then notified via sms, mail and HipChat so we could take immediate action and prevent extended downtime. Projects: - Designing and implementation of the entire IT platform from scratch. Invoicing, mail and sms sending, integration with mobile network partner, self-service universe, CRM system. Everything was made without an underlying billing platform. - Automatic gathering of sales leads via Facebook api and forwarding them to Actimizer/Herobase enabling customer service and telemarking to use the leads instantly. - Migration of 80000 customers from 3 to TDC's mobile network after TDC's purchase of Plenti.
