About
Hello there! I'm Alex, and I’ve been developing software since 2011. I’ve worked on a variety of projects, including APIs, mobile apps, AI apps, web apps, and even automated investment strategies. I love learning new things in tech and, more importantly, applying them to real-world problems. Recently, I’ve been focusing on web applications (full-stack, although I’m more frontend-focused) and the challenges that come with them.
