PROFILE

Khahani

Over seven months, contributed to the EasyEyes/threshold, EasyEyes/threshold-scientist, and EasyEyes/website repositories by building robust experiment workflows, scalable API integrations, and resilient deployment pipelines. Delivered features such as versioned glossary APIs, WebAssembly-based font processing, and Prolific recruitment flows, while improving authentication with OAuth 2.0 PKCE and enhancing error tracking using Sentry. Applied JavaScript, TypeScript, and React to implement frontend and backend improvements, including caching, retry logic, and CI/CD automation with GitHub Actions and Netlify. Focused on maintainability, performance, and security, the work enabled faster study launches, reduced runtime errors, and streamlined developer experience across the EasyEyes platform.

Apr 1, 2026

April 2026 performance summary focusing on features delivered, bugs fixed, impact, and technical skills demonstrated across EasyEyes/threshold, EasyEyes/threshold-scientist, and EasyEyes/website. Key features delivered: - EasyEyes/threshold: Comprehensive upgrade to the threshold experiment including WebAssembly modules for font processing and calibration; expanded build system; and broader experiment configuration capabilities with updated parameters and subproject dependency adjustments. - EasyEyes/threshold-scientist: Web app scaffold for online experiments with Prolific-driven participant filtering; API enhancements; UI/UX improvements for study launches; and performance optimizations to improve launch times. - EasyEyes/website: Prolific API integration enhancements (parameter handling, pagination, and a new filter-set endpoint); UX improvement by removing a Prolific warning; automation workflows via GitHub Actions for content management; production Pavlovia access token fix; and alignment of subproject references/documentation. Major bugs fixed: - Removed Prolific warning to reduce noise and improve user experience (threshold-scientist/website). - Pavlovia access token issue fixed for production deployments. - Added token validation before API calls across threshold and Pavlovia-related paths to improve reliability. - Various stability fixes: redirect dialog handling, blank tab and popup-blocker prompts, and addressing compile freezes. Overall impact and accomplishments: - Improved reliability, security, and deployment hygiene across experiments and study recruitment pipelines. - Faster study launches and reduced runtime errors, enabling researchers to run more experiments with fewer blockers. - Improved developer experience through streamlined configuration, submodule maintenance, and CI/CD automation. Technologies/skills demonstrated: - WebAssembly integration and advanced font processing/calibration workflows. - React frontend development and Prolific API integration (parameters, filters, pagination). - Token validation and refresh mechanisms for GitLab/Pavlovia integrations. - CI/CD automation with GitHub Actions and submodule/build-system maintenance. - Performance optimization and UX refinements for online studies and recruitment flows.
