$ cat about.txt

I'm a passionate backend developer with over 12 years of experience building scalable applications. Starting as a full-stack developer, I'm now transitioning to specialize in backend development, system design, and API architecture.

Throughout my career, I've designed end-to-end solutions for clients, from small business applications to complex workflow management systems. I'm currently studying software architecture concepts and modern backend patterns while pursuing Data Science and AI.

When I'm not coding, I enjoy teaching and sharing knowledge - having spent 5+ years as a technical instructor, I'm passionate about mentoring other developers and contributing to the tech community through education and content creation.
