Architected an adaptive UI system with platform-native design languages (Liquid Glass for iOS 26, Material for Android) while keeping a single shared design system. Enhanced real-time voice AI call experience by migrating from a socket-based approach to WebRTC, enabling seamless user interruption and robust voice activity detection for the Gemini live API. Profiled and optimized DevTools to reduce first-paint time by 35%, reduce janky frames by 40%, and shorten media upload time by 25%.

Reduced app load time by 40% by overhauling state management and adding background services for smoother data syncing, improving speed and user experience for over 40,000 monthly active users. Implemented a fully automated CI/CD pipeline using GitHub Actions, reducing deployment time by 60% and facilitating coordination in remote teams. Mentored a team of 5 developers in Agile/Scrum, introducing bi-weekly sprints and reviews that increased delivery speed and shipped 10+ features on time within 6 months.

Led migration of a Vue.js web application to Flutter, unifying codebase and simplifying deployment to three platforms, reducing technical debt. Authored a dedicated Flutter plugin to resolve complex character encoding issues for Farsi and Arabic characters conversion. Developed a custom high-performance Flutter data table component with lazy loading and smart pagination, reducing rendering lag by 70% for datasets over 10,000 rows.
