Thang Vay

I am a software developer and data professional with a passion for building intelligent systems, working with data, and creating clean applications. I recently graduated from Saint Louis University with a degree in Computer Science, and I love applying my skills to real world challenges.

Throughout my journey, I have had the opportunity to build walk forward backtesting models to study stock predictions, write secure system tools in Python, and automate business reporting. Whether I am writing SQL queries to audit complex portfolios at Pennymac, building automated pipelines, or designing a clean frontend interface, I enjoy creating software that is both reliable and engaging to use.

I specialize in artificial intelligence, data systems, and software engineering, and I am always looking for new ways to push the boundaries of what code can do. I am currently actively seeking full time opportunities in data engineering, data analytics, and software development, and would love to connect.
