About

As a Software Engineer with 3 years of experience building robust mobile applications, I've developed a deep passion for the backbone of any great software: a fast, efficient, and scalable database. My journey into mobile development with Flutter taught me that a beautiful UI is only half the story. True performance comes from optimizing how data is stored, accessed, and managed. This realization drove me to dive deep into database systems, particularly Oracle, and master the art of performance tuning and query optimization. I thrive on solving complex backend challenges to improve frontend speed. Whether it's refactoring a data model, optimizing a SQL query, or analyzing API performance with tools like JMeter and Postman, my goal is to build software that is not just functional, but exceptionally fast and reliable. I am currently seeking opportunities where I can leverage my expertise in both software engineering and database optimization to contribute to high-impact projects.
