About Me

Profile Image

I'm all about building scalable and robust applications, bringing over 5+ years of experience. As a Backend Software Engineer, I've driven efficiency improvements of up to 60%, thanks to my expertise in Go and JavaScript.

In my current role at Cudium, as a Senior Software Engineer, I've integrated backend systems with third-party applications, boosting our understanding of user engagement by 85%. Beyond coding, I enjoy mentoring, documentation, and spearheading security features for a safer application.

During my internship at Nomba, I honed Node JS, MongoDB, and Java skills, improving data persistence for vendor services and reducing fraudulent transactions by over 60%.
