PROFILE
Garvit Khandelwal
Over five months, contributed to the Submitty/Submitty repository by building and refining grading and submission workflows, focusing on both backend architecture and user interface stability. Developed a Python-based asynchronous daemon for submission clustering, replacing legacy PHP logic to improve scalability and performance. Enhanced grading transparency and reliability through UI improvements, automated testing with Cypress, and robust database management using PostgreSQL and Doctrine ORM. Addressed complex bugs in PDF rendering, table layouts, and CI/CD workflows, ensuring consistent environments and reduced manual intervention. The work demonstrated depth in fullstack development, performance optimization, and test-driven engineering, resulting in more efficient grading and reporting processes.

Jul 1, 2026July 2026 monthly summary for Submitty/Submitty: Delivered a Python-based asynchronous daemon to cluster submissions, replacing the PHP-based flow; introduced new database interaction scripts, a daemon job handler, and updated controller logic to boost performance and scalability. Fixed CI pipeline reliability by refactoring the DB check workflow, correcting database password handling, and implementing symlink-based configuration to ensure consistent environments and resolve branch/main diffs. Together, these changes reduce submission processing latency, increase throughput under high-load conditions, and improve CI/CD reliability and reproducibility. Demonstrated skills in Python development, asynchronous programming, database scripting, and CI workflow optimization; validated with unit tests for clustering and controller components.

Jun 1, 2026June 2026 performance summary for Submitty development focusing on delivering business value through robust backend architecture, performance optimizations, and improved reliability across grading and discussion features. Demonstrated capability in backend design (Doctrine entities, migrations, API controllers), performance engineering (PDF rendering with PyMuPDF and redaction-aware caching), data correctness and UI clarity (override stats bounds, date handling), and UX improvements (forum date picker, search UX) with solid test coverage (unit and Cypress) to reduce manual debugging and support scale. Overall impact: accelerated grading and reporting workflows, reduced PDF rendering times during bulk regeneration, improved accuracy and transparency of statistics, and a more reliable user experience for instructors and TAs across Submitty modules.

Apr 1, 20262026-04 monthly summary for Submitty/Submitty focused on stabilizing the grading UI PDF workflow and ensuring long-filename scenarios do not degrade readability. Implemented a targeted UI fix for dynamic PDF header behavior, which preserves visibility of the top of the first page in the TA grading PDF viewer and reduces manual intervention during grading. Impact: Improves grader experience, reduces confusion when filenames wrap, and minimizes risk of misgrading due to hidden headers. No migrations required; no breaking changes introduced.
