Developed and maintained the HWTeng-Teaching/202502-Financial-Econometrics repository over four months, delivering 31 features and resolving key bugs to support coursework in econometrics and financial modeling. Work included end-to-end pipelines for data analysis, reproducible regression workflows, and robust documentation scaffolding to streamline onboarding and maintenance. Leveraged R and SQL for statistical modeling, hypothesis testing, and CAPM analysis, while employing Git for version control and repository hygiene. Implemented lifecycle management for homework and release artifacts, integrated diagnostic testing, and established standardized project structures. The approach emphasized reproducibility, clarity, and maintainability, enabling efficient learning workflows and reliable deployment of analytical coursework.

Feb 1, 2025February 2025 monthly summary for HWTeng-Teaching/202502-Financial-Econometrics. Key outcomes include lifecycle support for a homework entry (313700018_JheAn-Liao): created and later removed within a batch, enabling reusable data scaffolding and safe teardown. Comprehensive repository documentation improvements were completed, including README.md scaffolding, multiple updates, and alignment with project-wide documentation standards via README.R synchronization. The HW0224 lifecycle and refactor were executed, covering creation of HW0224, renaming to HW0224.R, updates to HW0224.R, and the introduction of supporting docs (HW0224 2.16.R, HW0224 2.1 2.14.md), with subsequent cleanup of obsolete references to reduce noise. An HW placeholder was created to establish a documented entry point for future homework tasks. Cleanup of legacy references and obsolete HW paths was performed to fix broken links and reduce repo noise. Technologies and skills demonstrated include Git-based lifecycle management, batch operation design, documentation standardization (README.R/README.md), refactoring and naming conventions, and general repository hygiene. Business value includes safer data lifecycle operations, improved onboarding, consistent documentation, and reduced maintenance overhead across the project.
