December 2024: Delivered Clerk SDK waitlist entry management API for clerk/clerk-sdk-go, enabling programmatic handling of waitlists. Key features include endpoints to list and create waitlist entries, along with the underlying data structures and client logic. Introduced a Notify option in CreateParams to control notification behavior. No major bugs fixed this month; focus was on feature delivery and code quality. Impact: accelerates waitlist workflows for developers, reduces onboarding friction, and enables seamless integration into client apps. Technologies demonstrated: Go, REST API design, client library development, data modeling, and PR-driven development (PR #360: feat: Add support for waitlist entries endpoints; PR #361: chore: Add notify to waitlist entries).
