Hi, I'm Khahani 👋

Maintained and integrated a JavaScript sizing widget on branded product-detail pages in less than a month, achieving sub-500 ms compute times and 99.9 % uptime with a lightweight implementation. Styled more than ten brand-specific widget variations that boosted conversion rates by 3–9 × and cut returns by 25–40 % for leading luxury fashion retailers within six months. Added WCAG 2.2 AA compliance checks and wired event hooks into client analytics dashboards, delivering real-time insights without affecting page speed in twenty weeks.

Configured GitHub CI pipelines to raise release reliability to 90 percent and kept more than ten deployments going out each week while onboarding two new developers to the project. Delivered a finance application in eight months by building a component-based React single-page app with JWT authentication and 90 percent test coverage that later passed an external security audit. Refactored the internal CV builder by migrating it from Angular to React, TypeScript, and React Query, cutting load times from 6.5 seconds to 1.9 seconds and halving ongoing development effort.

Collaborated in a cross-functional team to deliver a Trello-style task app serving more than 1,000 daily users, reviewing pull requests and shipping drag-and-drop boards built with React hooks. Implemented secure JWT authentication with silent refresh and route guards, and introduced Playwright tests for login, CRUD, and drag-and-drop flows to reach an 80 % pass rate in continuous integration. Added code-splitting and lazy loading that trimmed the initial bundle by 25 % and cut First Contentful Paint to 2.8 s, enhancing the user experience within three months.

Earned a place in EPAM's selective 40-hour React/TypeScript internship and, over eight weeks, worked with the team to ship an e-commerce single-page application that used Hooks, Context, and a reusable Bootstrap component kit. Reached Lighthouse scores above 80 and full PWA accreditation while following a Scrum process with daily stand-ups, sprint demos, and Git-based code reviews to keep the work on track.
