Sarang Joshi contributed to NYPL/digital-collections by delivering backend and frontend enhancements focused on data integrity, analytics, and deployment reliability. Over five months, Sarang unified item data models, introduced server-side pagination and endpoint-level caching, and integrated GA4 analytics for richer user insights. He improved test coverage and automated QA using Playwright, refactored AV playback analytics with a custom player, and migrated deployments to GitHub Releases with CI/CD checks. His work included security hardening through dependency upgrades and CI modernization. Sarang’s technical approach leveraged TypeScript, React, and Next.js, resulting in faster, more reliable item rendering and streamlined release processes.
December 2025: Focused on security hardening and CI stability for NYPL/digital-collections, delivering a hardened dependency baseline and a more robust development pipeline. Key outcomes include a Next.js upgrade with vulnerability remediation and a modernization of CI tooling to Node.js 22 plus ESLint improvements. These changes reduce security risk, improve code quality, and accelerate release readiness.

August 2025 highlights analytics and deployment improvements across NYPL/digital-collections and UniversalViewer with a focus on measurement fidelity, data quality, and release reliability. Key features delivered include (1) Audio-Visual Playback Analytics with a CustomAVPlayer, milestone tracking (10/25/50/75/100%), and deduplicated end-event logging; GA4 integration extended for playback metrics. (2) GA4 Tracking Enhancements for media and content/resource types, including start playback events, refined resourceType/contentType extraction, and standardized missing-field handling. (3) Deployment Process Improvements shifting prod deploys to GitHub Releases with pre-deployment CI checks and updated README. (4) OpenSeadragon download event tracking delivering IIIF.DOWNLOAD telemetry with payload details. Major bugs fixed include removal of duplicate media-end logging and data quality fixes such as standardized GA4 missing values and improved field naming. Overall impact: more accurate, actionable analytics, reliable release processes, and richer viewer telemetry enabling data-driven product decisions. Demonstrated technologies/skills include GA4/event tracking, component refactoring and modularization, OpenSeadragon integration, and CI/CD with GitHub Releases and changelog governance.
