What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a dedicated Principal Software Engineer with a strong background in developing scalable solutions and leading cross-functional teams. My journey began with a Bachelor of Science degree in Computer Science from the University of Florida, where I honed my skills in software development and engineering practices. Over the years, I have successfully translated complex systems, introduced best practices, and automated processes to enhance productivity and efficiency.

At Tangelo, I led the migration of an extensive AdonisJS web API to Express, ensuring zero vulnerabilities while implementing CI/CD processes using AWS EKS. My role at Georgia Institute of Technology allowed me to teach Test-Driven Development in Python and mentor junior engineers, further solidifying my commitment to fostering growth in the tech community. I thrive in environments that challenge me to innovate and collaborate, and I am passionate about leveraging technology to solve real-world problems.
