Engineering Experience

Software Engineer

MealMatch AIRemoteNovember 2025 – Present

Owned end-to-end Customer.io SDK integration in React Native, taking a broken PR through diagnosis, refactor, and production launch: identified the root-cause SDK misuse preventing iOS device registration, consolidated 11 direct SDK call sites into a single TypeScript service abstraction, instrumented 12+ lifecycle events (account creation, onboarding, subscription, meal plan, account deletion), and wired user identity cleanup into both logout and account-deletion flows so push notifications terminate cleanly, covered by 37 Jest unit tests.
Created an AI context and documentation system (structured YAML + human-readable guides) to keep repo context consistent for contributors and AI tools, significantly reduced prompt bloat, improved the speed/accuracy of code changes, and reduced token usage by 40% across multiple agent runs.

Software Engineer Intern

American Dog SocietyRemoteJune 2024 – July 2024

Migrated Next.js Page Router to App Router with Server Components, cutting client-side JS bundle size and improving load times by 50%+.
Engineered a modular design system with Tailwind/DaisyUI to replace global CSS, reducing conflicts, improving scalability, and enabling more maintainable component-level styling.

Software Engineer

ReactimeNew York, NYNovember 2023 – April 2024

Leveraged the Chrome Debugger API and React DevTools to capture and visualize DOM changes in real time, streamlining accessibility testing, reducing manual review time, and helping developers identify performance or accessibility issues faster.
Optimized React’s rendering logic by implementing conditional component updates and controlled accessibility tree generation, reducing time to first paint by 25% and improving overall UI responsiveness.
