Claude Code doesn't make your product better. It makes it bigger.

Shipping faster has never been easier. Shipping better has never been harder. Claude Code is the most impressive code-generation tool I've ever used. It's also the fastest way to turn a clean codebase into an unmaintainable mess if nobody's paying attention. And right now, not enough people are paying attention. The output is not the outcome Ethan Ding recently published a piece argu...

ROAS 100% is not the breakeven point — what most ad reports get wrong

ROAS 100% is not the breakeven point — what most ad reports get wrong

I keep hearing this line in marketing reviews: "Our ad ROAS is 300%, so we're profitable." For a 50% gross margin product, that's true. For a 20% gross margin product, that's a loss. The same line, the same number, opposite conclusions. This isn't an exotic edge case. ROAS alone tells you nothing about whether you're profitable. The math is small but it almost never gets put on the same slide as ...

How I Passed the AWS Certified AI Practitioner in 2 Weeks Using 100% Free Resources (While Working Full-Time)

Two weeks ago, if someone had asked me about most AWS AI services, I probably would have smiled confidently… and changed the topic. Apart from a basic understanding of AWS and a few familiar services like Amazon S3, AWS IAM, and Amazon Cognito, I was definitely not what you would call an AWS certification machine. In fact, this was my very first AWS certification exam. Fast forward 14 days late...

Stop undercharging: I built an AI pricing co-pilot in MeDo

Most freelancers I know lose money on every project. Not because they're bad at their craft, but because they're bad at pricing. BuiltWithMeDo I see it all the time. A one-line quote, no rationale, a single number that gets negotiated down to nothing. Independent professionals consistently undercharge by 30 to 50 percent versus market rates.

Beyond the APK: Mastering Model Lifecycles and AICore in Modern Android Development

The era of "small AI" on Android is officially over. For years, mobile developers treated machine learning models like slightly oversized image assets—small TensorFlow Lite files tucked away in the assets folder, bundled within the APK, and loaded into memory with a simple function call. But as we enter the age of Generative AI and Large Language Models (LLMs), that traditional paradigm hasn't jus...
