The technical evolution of a global video platform's user management features, migrating to a microservices domain. These modules manage user information used by OSS/BSS systems, other platform components, and end user-facing front ends with millions of concurrent devices in Latin America.

My contributions involved migrating from a monolithic service back end with a C# and SQL Server relational database to a set of microservices running on a NoSQL database and using Node.js, Couchbase, Apache Kafka, Kubernetes, and Istio. Deployed a synchronization mechanism using Kafka Connect to allow gradual services migration.

Technically led the development of the set-top box middleware. It included the REST and Multicast back-end platforms integration; Qt and QML user interface; video playback protocols, such as RTP, Smooth Streaming, PIFF/H.264, and AAC; encryption and CA/DRM with PlayReady, and Nagra; hardware and chipset integration for Linux, Broadcom Nexus, RCU, WiFi, and HomePNA; third-party components and applications, such as Frog by WyPlay, and Netflix; and monitoring and throubleshooting tools.

The project required a strong interaction with the network and platform engineering teams to define service specification details and troubleshoot issues. It also involved frequent collaboration with the product teams to understand requirements and plan its implementation.
