PROFILE

Sean Pollock

Sean Pollock developed and maintained core multimedia streaming features across several Viam Robotics repositories, including viamrobotics/rdk and viamrobotics/viam-typescript-sdk. He designed and implemented video streaming APIs and services using Go, TypeScript, and Protobuf, enabling dynamic video configuration, real-time media control, and robust error handling. Sean addressed reliability challenges by refining concurrency, bitrate adaptation, and stream state management, while also improving developer experience through comprehensive documentation and test coverage. His work established scalable, cross-platform video data access and enhanced system stability, reflecting a deep understanding of backend development, gRPC integration, and distributed service architecture in production environments.

Nov 1, 2025

Month: 2025-11 — Delivered core multimedia streaming capabilities across two repos. Key features introduced: a Video Streaming Service API in viamrobotics/api (proto-based) and a Video Streaming Service via gRPC in viamrobotics/rdk, enabling retrieval of video streams/chunks and execution of commands. These efforts lay the foundation for richer client experiences and scalable multimedia workflows. No major bugs reported this month; focus was on design, implementation, and cross-repo integration. Technologies demonstrated include Protobuf definitions, gRPC transport, service-oriented architecture, and collaborative development (co-authored commits). Impact: expanded business value through multimedia capabilities and improved system extensibility.

Jan 1, 2025

January 2025: Strengthened streaming reliability in viamrobotics/rdk with two targeted changes. Bug fix: GetStreamOptions now returns only even resolutions; GenerateResolutions adjusted to ensure even dimensions to avoid client-side errors. Feature: Maintain dynamic resolution preferences across reconfigurations; reapply Resize transformations when needed; fallback to original source if resizing fails; notify stream state of reset. Impact: More stable, predictable streaming experiences; reduced interruptions during reconfigurations; improved resilience. Technologies: stream option validation, dynamic resizing, state management, fallback mechanisms. Commit references: RSDK-9702, RSDK-9703.
