About Me

Hello, I'm a Class of 2026 student at the University of Washington Seattle and a Software Engineer that's eager to try new things and loves logic puzzles.
My current interests include video games from my childhood like Minecraft, Skyrim, and Stardew Valley as ever since I was young, coming up with new ideas meant that I could bring them to life in these games through mods.

Midas Core Financial System Screenshot

Midas Core Financial System

A high-throughput financial transaction engine developed during a JPMC Software Engineering program. The system processes real-time financial data using Apache Kafka for asynchronous message handling and ensures data integrity through a SQL database (H2/JPA). Features include automated transaction validation based on user balance and ID verification, a decoupled REST API integration for dynamic incentive calculation, and a GET endpoint for real-time balance queries. The project leverages Spring Boot's dependency injection and embedded Kafka for robust, scalable backend performance.
