• Introduced atomic design principles, building a library of 20+ reusable components and a GitLab-powered Storybook pipeline that reduced handoff friction and accelerated feature delivery across the product.
• Built and owned a monthly automated insights pipeline using Node.js Cron jobs, MongoDB aggregations, and a custom email template delivering data-driven engagement reports to 100+ partner schools with zero regressions.
• Built a reusable TypeScript form validation library from scratch, eliminating duplicated validation logic across 12+ forms with a consistent, type-safe system backed by Jest unit test coverage.
• Established a Jest testing baseline across React components, shared utility functions, and API response shape validation for role-based access, improving refactor confidence and reducing manual regression surface area.
• Rearchitected legacy dashboards with role-based widgets, shortcuts, and CTAs in collaboration with the Co-Founder & CDO, driving a 23% increase in CTA click rates and measurable improvements in feature adoption.

• Helped scope and ship a dashboard rebuild from scratch in under 6 months, improving the core product experience for 100+ users alongside a full company rebrand.
• Maintained and extended a Syncfusion calendar component, implementing recurring appointments, cancellation and no-show fee logic, and appointment status tracking across the platform's core clinical workflow.
• Integrated Google Calendar API with two-way sync, enabling real-time appointment management and reducing scheduling conflicts across clinician workflows.

• Wrote and maintained Cypress E2E test suites covering full user flows, form validation, click handlers, and API calls with DRY patterns that reduced regressions across core onboarding and scheduling workflows.
• Performed manual testing across payment ledger workflows and form-based user flows, catching calculation errors and UI inconsistencies before production.
• Worked directly alongside developers in daily standups and 2-week sprint cycles using Git, Postman, and Monday.com to keep test coverage aligned with active development.
