Engineered and deployed high-performance React Native mobile applications and integrated backend systems with an emphasis on scalable fullstack architecture and minimizing technical debt. Integrated AI-assisted development tools (Cursor/GitHub Copilot) into engineering workflows to improve team velocity and accelerate end-to-end feature delivery. Drove technical execution within Scrum cycles by contributing to sprint planning, backlog grooming, story estimation, and leading technical alignment sessions.

Architected secure cross-platform mobile applications using React Native and optimized API request/response payloads to minimize data sync latency. Built automated fullstack CI/CD pipelines using GitHub Actions and Fastlane to remove manual deployment dependencies for mobile clients and cloud builds. Engineered custom native module solutions (Java/Kotlin) and server-side optimizations to ensure seamless data flows and maximize UI responsiveness. Contributed technical insights throughout Scrum planning, estimations, and architectural alignment.

Developed high-availability mobile applications and robust backend logic using React Native and NodeJS within a regulated financial/superannuation environment. Restructured core app state management and improved relational database queries, reducing technical debt and increasing team onboarding velocity. Built a custom internal web management portal from scratch using ReactJS, improving daily operational workflow efficiency for product owners. Integrated automated tests (Jest, Detox, Cypress) into Jenkins-based fullstack delivery pipelines alongside SonarQube code scanning.
