I’ve built an e-commerce platform with Java, Spring Boot, React.js, and MySQL, including RESTful APIs for product catalogs, carts, and orders. I used Spring Cache to reduce p95 response time by about 30% and integrated Stripe payments with webhook-driven order fulfillment.
For the platform, I implemented JWT authentication and role-based access control across user and admin roles, and built a React.js frontend using Redux Toolkit. I’ve also developed a blog REST API with Spring Security, Hibernate, and a normalized MySQL schema.
In a separate SQL data warehouse analytics project, I designed a star schema and wrote analytical T-SQL queries, reusable views, and customer and product segmentation logic. I’ve solved more than 800 LeetCode problems across arrays, trees, graphs, dynamic programming, and binary search.
