PROFILE
Jack Chen
Worked on edgexfoundry/edgex-go, focusing on backend reliability and system stability over four months. Addressed critical bugs in build systems, API validation, and scheduler synchronization, using Go, Makefile, and PostgreSQL. Improved build reliability by consolidating LDFlags handling and standardizing Makefile variables, which reduced CI failures and streamlined onboarding. Enhanced API error signaling and input validation to ensure safer data access and clearer client responses. Fixed scheduler bugs by aligning in-memory and database states and resolving race conditions with atomic operations, preventing missed jobs and panics. Demonstrated strong backend development, concurrency, and DevOps skills in production-critical environments.

Mar 1, 2026Month: 2026-03 — performance-focused monthly summary for edgexfoundry/edgex-go. Delivered a critical crash fix in Scheduler Action Record to stabilize scheduled callbacks and prevent nil pointer panics caused by racing code paths. Replaced racy getGocronJobByID + LastRun() lookups with an atomic time storage approach using atomic.Int64 in BeforeJobRuns, ensuring the last-run timestamp is captured safely and consistently. Removed the getGocronJobByID helper. The change hardens scheduling against deletion, shutdown, or limitRunsTo scenarios and reduces exposure to race conditions that previously caused panics. This work resolves a long-standing reliability bottleneck and improves overall system stability for time-based automation across devices.

Jan 1, 2025January 2025: Delivered a reliability-focused scheduler improvement in edgexfoundry/edgex-go by fixing the ScheduleJob out-of-sync issue between the scheduler manager and the database. The change ensures that scheduled jobs are always created and started within the manager, independent of trigger conditions, aligning in-memory scheduler state with persistent state. Result: more reliable task execution, fewer missed or stale schedules, and smoother business operations across dependent services.
