During a two-month period, Edgar Chacon developed foundational backend features for the SE4CPS/DMS repository, focusing on Python and JavaScript. He established initial project scaffolding and stabilized PostgreSQL database connectivity, enabling reliable local and staging development. Edgar implemented API endpoints to measure database query performance, wiring the frontend to trigger and display execution times for both fast and slow query paths. His work included updating database connection configurations and building instrumentation for performance benchmarking. The depth of his contributions lies in creating a maintainable codebase and providing measurable backend performance, supporting future optimizations and improving the overall development workflow.

Apr 1, 2025April 2025 performance instrumentation for SE4CPS/DMS focused on establishing measurable database performance paths. Delivered two API endpoints to measure query performance, wired frontend to trigger and display execution times, and laid the groundwork for a formal fast vs. slow query benchmark. The fast path is functional; the slow path is implemented but currently not working as expected, with debugging underway. This effort creates a foundation for data-driven optimizations and improved visibility into backend performance, supporting reliability and user experience goals.
