WindMit Mobile App
WindMit Mobile is a high-performance React Native application designed to streamline complex property inspections. I led the full development of this app, turning traditional paper-based processes into a fast, modern digital solution tailored for field inspectors. With deep expertise in React Native, TypeScript, Redux Toolkit, and React Navigation, I crafted a multi-step inspection workflow that is both powerful and user-friendly. To enhance performance and usability on mobile devices — especially in field conditions — I implemented a step-based form system. Each step of the form is saved individually to the backend, allowing inspectors to complete their tasks incrementally without losing progress. This not only improves performance by reducing memory load but also gives users the flexibility to pause and resume work effortlessly. I used React Hook Form with optimized field-level rendering to ensure smooth interaction across hundreds of inputs, including images, checkboxes, and digital signatures. Data persistence was handled via Redux Persist, allowing offline continuity and seamless restoration of state. The backend, built with Node.js and Express, features secure JWT-based authentication, OTP verification, and real-time form handling. I also integrated PDF generation using PDF-lib, Cloudinary for image storage, and Nodemailer for email communications. Stability was further ensured with Sentry, providing real-time error tracking and performance monitoring. This project reflects my ability to design scalable mobile systems, optimize app performance for real-world use, and build complete solutions that solve practical challenges for clients and users alike.
Greenprint – Personal Finance & Wealth Management App
A client reached out to me with a clear and forward-thinking idea: to build a futuristic mobile app that would help users take control of their finances, set goals, monitor market trends, and get rewarded for learning about money. They needed a sleek, high-performance solution that merged real-time financial data with a premium user experience. I transformed this concept into Greenprint — a cross-platform personal finance application with an intuitive frontend and a powerful, secure backend. To ensure a smooth user journey, I implemented flexible authentication options including Face ID, Google login, phone login, and password recovery. I also developed a user settings panel and in-app support system, making it easy for users to manage their preferences and get assistance when needed. The app supports both dark and light modes to enhance user comfort. The Home Dashboard connects with users’ financial accounts through the Plaid API, showing real-time balances, transaction history, net worth, and visual income vs. expense charts. I also integrated live financial news, stock and crypto data, and embedded Twitter content for up-to-the-minute updates. I built a gamified Marketplace where users can earn coins by completing daily quizzes or participating in giveaways — and redeem them for books, courses, or exclusive content. For Greenprint Premium users, I developed advanced modules for personalized monthly plans, goal tracking, expense forecasting, and wealth health check-ups. On the backend, I built a custom admin panel with role-based access controls, allowing secure management of users, plans, and store items. I integrated APIs for market data and used Firebase Auth with JWT for secure, scalable authentication. I also added analytics to track user engagement and behavior. Technology Used: React Native · Node.js · Express.js · MongoDB / PostgreSQL · Firebase Auth · JWT · Plaid · Twitter & Market APIs Outcome: The result is a robust, modern mobile app that exceeded the client's expectations — offering users a complete financial toolkit, from real-time insights to financial education and rewards. Greenprint empowers users to make informed decisions and take control of their financial future.
