It offers a world of additional programmes and features without having to leave the current programme.• During the CRB Coexistence project, I was influential in the delivery of the feature across multiple platforms, from the initial design to helping the QA team. It was a great challenge due the time constraints and the involved changes of many different components. I participated in the development, design and planning of every single task related to this work. I created two MHEG tools that helped test and provided validation for broadcast changes, and it still used to verify persistent storage on broadcast devices. During rollouts, I improved the monitoring tools, and the system alerts to provide quicker / better feedback. • Key Technologies used: Java, Javascript, Mheg, OpenTV, Php, Ruby, Cucumber, Spring, Phyton, SQL, XSLT and various Broadcast technologies.
