PROFILE
Brian Nguyen
Worked on the UCSolarCarTeam/Helios-Telemetry repository to deliver scalable telemetry data access and modernize the platform’s frontend and backend. Enhanced data storage by implementing DynamoDB tables with time-based indexing and optimized queries using QueryCommand, reducing latency and improving analytics reliability. Upgraded the stack to Next.js 15 and React 19, streamlining developer workflows and accelerating deployment through CI/CD improvements. Addressed build and linting issues by refining Docker image tagging and enforcing stricter ESLint rules. Used TypeScript, Node.js, and AWS extensively to ensure maintainable, efficient code, while fixing data correctness bugs to align API behavior with expected contracts and business needs.

May 1, 2025May 2025: Delivered performance and data correctness improvements for Helios-Telemetry in UCSolarCarTeam. Refactored DynamoDB data access to use QueryCommand with proper index conditions, replacing ScanCommand and reducing latency for telemetry data retrieval. Fixed data correctness by ensuring fake telemetry timestamps are generated in seconds. Resolved critical data-access bugs for date-range and packet retrieval (scanPacketDataBetweenDates and getPacketData), aligning behavior with expected API contracts (#229). Outcomes: faster, more reliable telemetry analytics and improved trust in dashboard data.
