Software Engineering Intern (Video Platforms)
Partner with Sr. Engineering leads to support the architecture, design, development, and deployment of platform services for Fox’s digital video products across web, mobile as well as the next generation of devices. While supporting the team, you will develop tools and services using a combination of Node.js, Python, and other relevant technologies that power our Video On Demand ingestion platform and Livestream Monitoring tools.
Fox- Multi CDN Dynamic Switching
- Design and develop a decisioning service that provides a Multi CDN solution ensuring delivery of seamless, high performance, high resolution live stream videos across the globe to Fox users.
- For a Multi-CDN setup, same content/ assets are distributed across multiple Content Delivery Networks for distribution in different regions across the United States. However, CDNs vary in performance throughout the day, sometimes leading to videos buffering and pausing during the stream which leads to a negative users’ viewing experience.
- The multi cdn solution intelligently switches the streams to come from a different Origin/CDN when these issues occur, to ensure high resolution videos are delivered to the users without any pauses, buffering during playback.
- The intelligent switch ensures that the HTML5 players embedded in web page provide a good playback. The decisioning service leverages the metrics from players across the globe to decide which CDNs perform the best at every point of time.
- Service built using NodeJS, deployed on AWS Lambda and Amazon's EC2 instances.
VDMS API Validation
- Invoke VDMS apis and validate the Live player content hosted by Verizon for Fox video assets, especially HTTP Live streams
- Design an authentication service that invokes Adobe's Authentication service and performs a login of the given user to various MVPDs (Multi-channel Video programming distributors) and returns an Authentication token.
- To ensure that the Live playing programmes on about 200 owned and non-owned channels across the United States are running accurately according to the EPG Listings(Electronic Programming guide) available, returned by the APIs.
- If errors are detected, they are streamed/logged to multiple event collectors of Splunk for the operators and stakeholders to act on them.
- Organize processes in cluster with Master and Worker processes serving over 190 Video distribution stations concurrently. Master spawns workers on death automatically, keeping uninterrupted service to these stations.
Software Developer
Global Connectivity Platform or Mobile Virtual Network Operator
Develop an MVNx Portal that provides a User Interface to MVNOs for invoking a set of APIs to enable them to access Provisioning data and Customer Service to the customers. It would be a portal where Customers can login and recharge or topup their Network device( USB Sticks ) with the Internet (3G/2G) Data. The process went through a Workflow process that included an approval with the managers or supervizing officers of the Employee/Customer.
- Develop back end services using Java Spring Boot framework to persist data into the database(MySQL) and expose these functionalities as RestFul APIs to be invoked by the Client-facing Front End Application
- Actively designed and implemented a Proof of Concept (POC) to demonstrate the Client , the values of moving the single Monolithic Application into the MicroServices architecture which would make the Application Cloud Native and Cloud ready. The Applcation was deployed on HP owned MicroCloud HPE Helion -Stackato.
- As a Demonstration to the Client, showed how Logs can be streamed out of Applications on the cloud, How the overall Health of the Application's health can be monitored using a Product called APP DYNAMAICS. It also involved a demonstration of Auto Scaling of the application where new instances were automatically spawned for the application due to the rise of the number of incoming requests.
Vodafone Global Enterprise (VGE) and Single Access Partner Portal (SAPP)
