About
I have been studying and developing software since 2018, with an increasing focus on backend systems in recent years.
I mainly focus on developing robust backend services and APIs — working with relational and NoSQL database modeling, authentication, service integration, WebSockets, payment gateways, and Docker infrastructure.
My progression started with curiosity and self-taught experimentation, grew into consistent public building on GitHub, and today is dedicated to software engineering best practices and solving real system problems.

First Contact
Curiosity & Self-Taught Exploration
This was when I started exploring code on my own. I didn't have a defined career path yet; it was driven by curiosity and a genuine desire to understand how software works under the hood.
"I grasped core programming logic and realized that solving problems through code was what I truly wanted to pursue."
