I'm working with Mphasis on Charles Schwab's ThinkOrSwim trading application, addressing security vulnerabilities and strengthening exposed-method checks.

I've supported version upgrades, resolved server data-retrieval bugs, and expanded test cases across modules to improve coverage. My training included Java, multithreading, MySQL, MongoDB, Spring, JUnit, and Mockito.

I also built a Spring Boot e-commerce backend, a Phaser space-war game handling 50+ concurrent objects, and a Java Segment Tree visualiser. I've solved 2,000+ problems across competitive programming platforms.
