About
I’m Rynku Maria Raju, a software engineer with about two years of experience building and supporting web applications—especially with Ruby on Rails, JavaScript, SQL, and REST APIs.

I’ve worked on security remediation and automated testing in production environments, and I enjoy collaborating with teams to understand requirements, troubleshoot effectively, and deliver improvements that make systems safer and easier to maintain.
