@brianw322

I’ve delivered full-stack mobile and web platforms from the ground up, with React Native for cross-platform apps and React/Firebase for scalable B2B dashboards. In a recent project, I built a React Native health & fitness app that integrated gamification mechanics (streaks, leaderboards, push notifications) to increase retention by 40%. On the web side, I architected a React + Firebase assessment tool with real-time scoring, custom dashboards, and secure multi-tenant authentication. Both platforms were designed for scale, handling thousands of concurrent users with smooth performance. I bring 6+ years of experience across React, React Native, Firebase, API design, and auth flows. What excites me about your project is the dual challenge: building an engaging consumer-facing mobile product while also delivering a polished B2B platform that drives operational excellence. My goal would be to accelerate your roadmap with production-ready, clean code and scalable architecture—whether as a long-term freelance partner or in a CTO-style role helping shape technical strategy.

I will structure both projects with modular codebases, enabling future scaling and international deployment. I will collaborate directly with you to align technical delivery with business vision, offering clear communication and autonomy throughout the process. The stack will be optimized for performance, user engagement, and operational excellence with Firebase handling backend, auth, and cloud functions. Testing and CI/CD pipelines will be set up to ensure smooth updates across web and mobile. I have successfully delivered full-stack React/React Native platforms that scaled to 50k+ users with measurable improvements in engagement and efficiency. I’m excited to bring this experience to your project in Chennai or Bangalore. Thanks.
