Dec 1, 2025December 2025: Implemented timezone-aware countdown timers for priority and regular application deadlines (ET) and updated the login page deadline to 2026-01-01 for hack-duke/portal.hackduke.org. This improves user visibility of upcoming deadlines and aligns the 2026 cycle, reducing missed deadlines and support overhead. No major bugs reported; changes are isolated to the countdown UX and timezone handling.

Jan 1, 2025January 2025 performance summary for hack-duke/portal.hackduke.org. This period focused on delivering core applicant-data improvements, UI clarity, and turning on end-to-end automation and observability to accelerate safe releases. Key features delivered: 1) Applicant Data Model Enhancements: replacing birthDate with age, adding a phone field, and making MLH email permission optional by default; frontend forms and backend schema updated accordingly. 2) Countdown UI Enhancement: custom CountdownRenderer with clearer UI text and CSS adjustments for better integration. 3) CI/CD Pipeline, Docker Deployment, and Observability Enhancements: CI/CD setup with Docker build/push to AWS ECR, multi-arch builds via Buildx, improved EC2 deployment steps, and enhanced observability/debugging capabilities. Major bugs fixed include MLH permission default flow, YAML/CI config formatting, switch to docker buildx to stabilize builds, and fixes for variable typing and heredoc expansion in CI scripts. Overall impact: improved data quality and consent handling, clearer user interface, and significantly faster, more reliable deployments with better monitoring. Technologies/skills demonstrated: data model migrations, frontend/backend coordination, Docker, AWS ECR/EC2, Buildx multi-arch builds, CI/CD orchestration, YAML scripting, and observability instrumentation.
