Monitoring system of the low latency video stream protocol

At AWS I helped to build correct and low latency distributed streaming service for Prime Video.

Achievements:

• Improved the data pipeline components written in Rust on top of AWS S3. The improvement implemented the support the new format of the data. Simplified some subsystems utilizing Rust features.
• Taught Rust to the colleagues with various backgrounds.
• Designed and implemented more precise calculation of loading of the nodes of the streaming service. This improved a high load system written in Go. The design required me to coordinate the work of people across the globe.
• Implemented hot-reload of the configuration in a high load system written in C++. The configuration carried information about the changes in the fleet of server clusters distributed across the globe. Extended the tech stack of the project and improved the automated testing.
• Fostered the new model of server clusters for the streaming service. Designed the project and the plan of work. Managed the execution of the plan across multiple teams.

Responsibilities:

• Designing the system components, clarifying the requirements from a set of departments involved in the process.
• Driving the design process from the idea to the paper, dealing with ambiguity in the inputs and lack of data.
• Presenting projects to the team.
• Implemented the components using a set of technologies: Rust, Go, C++, Python, Git, Amazon Web Services, Docker.
• Updated the old development environments according to the security requirements.
• Coached the team on matters related to Rust.
• Maintained the software in production and investigated issues that caused customer impact.
