About Me

Outside of work, I spend much of my time learning software development and turning what I learn into real applications.

What started with learning how websites work has grown into building full-stack applications, APIs, and AI-powered tools. Each project gives me something new to figure out and that's the part I enjoy most.

Right now, I'm focused on becoming a stronger developer by building larger, more challenging projects and understanding the decisions behind them. My goal is simple: keep learning, keep building, and turn this into my full-time career.
