Experience
Financial Tracking App
I designed and developed a financial tracking application that integrates with users' bank accounts and investment portfolios to monitor savings activity and project net worth over the next 10, 20, and 30 years. On the back end, I used Java and Spring Boot for API development, Hibernate for database ORM, and MySQL/PostgreSQL for secure data storage. For the front end, I implemented React to create an intuitive user interface.
I developed complex algorithms to calculate users' net worth and project future growth based on current savings patterns and market trends. Additionally, I built secure integrations with financial institutions, enabling the automatic syncing of savings, income, and investment data. I also created interactive dashboards that allow users to visualize their financial future and make data-driven decisions.
To ensure data security, I implemented OAuth for authentication, encrypted sensitive information, and applied secure data-handling practices. I also optimized the application to handle large volumes of financial data efficiently, ensuring real-time updates and projections without performance issues.
