A developer who enjoys making ideas real.
I care about how software fits into real life: remembering important days, finding scattered knowledge and making repetitive work easier.
From mobile apps to web, desktop tools and AI tools, I enjoy the whole journey from idea and design to development. I share what I learn while building these projects.
