I'm a software engineer based in Naperville, Illinois. With 6 years of software development experience and 19 years in IT, I can readily excel in any environment. My diverse background spans multinational corporations like Tesla and E. & J. Gallo, as well as start-ups and freelancing.
I've created pragmatic solutions to numerous complex problems, prioritizing scalability and engineering efficiency. Currently, I'm building full-stack frameworks for Tempus AI's DNA sequencing pipeline, improving delivery timelines, and streamlining user experience.
My commitment to continuous learning and growth empowers me to tackle increasingly challenging issues and deliver high-impact, easy-to-maintain solutions.
