Hello 
there! 
👋

I'm Michael James Carnaje, a software engineer from the Philippines with 4 years of experience. I enjoy building products that address real user needs—whether that's through web applications, mobile apps, or automation tools. My work often involves integrating AI-powered features; I've built with models like GPT, Claude, and open-source options such as Llama and DeepSeek. I'm always learning new technologies and aim to deliver solutions that make a practical difference.
