I designed and implemented the Source-2-Screen (S2S) service, which provides a tool-chain to media collection holders and developers for the storage, processing and delivery of media assets. S2S is currently used by production teams, collection/archive managers, and media service providers including BAFTA, BBC, RTS (Royal Television Society), Focal International, and AIB (Association of International Broadcasters). S2S handles over 5 TB of video processing and delivery per month through a set of novel resource allocation and optimization algorithms that are implemented over Amazon's Web Services (AWS) cloud infrastructure. The service is available at: https://www.source2screen.comTechnologies used:● Backend: PHP (Laravel), Java, C++ (Qt 5)● Frontend: HTML5, Javascript (jQuery), CSS● Databases: MySQL, DynamoDB● APIs: AWS (EC2, S3, Cloudfront, DynamoDB, Cloudwatch, IAM), Stripe, Trello● SDLC and testing tools: Git, PHPUnit, XDebug, Selenium
