Good work is cheap, Great work is rare
AI has solved 80% of all engineering problems, all that's left is taste and style. And that 20% is where I thrive. Being a software engineer for me means I use my skills to solve complex problems and build meaningful products. In today's world, form matters just as much as function and I care deeply about both. My love for design lead me on a path to design engineering, and I write about my journey here.
