[Patterns] AI Agent Error Handling That Actually Works

Most AI agent tutorials show the happy path. Your agent calls an LLM, gets a response, does the thing. Ship it. Then production happens. Rate limits. Timeouts. Malformed responses.

How I Built a Lead Gen Machine That Finds My Clients on Upwork

Two of my current clients came from the same system: a Python scraper that monitors Upwork every 20 minutes, scores each job with AI, and sends me a Telegram alert when something scores above a 6. I didn't find them. The system did. This is how it works. The problem Upwork's search is f...

Why We Ripped Function Overloading Out of Our AI Toolchain

The history of programming languages is a timeline of offloading cognitive weight. Assembly abstracted the registers. Python abstracted the memory management. Throwing generative AI at a complex, feature-heavy language reverses this progress. The syntax itself gives the machine too much room to impr...

Testing AI-Generated Code: How to Actually Know If It Works

I shipped a bug to production in January that embarrassed me. Not a subtle bug. A bug where a rate limiting function the AI wrote silently swallowed errors and returned true for every request, which meant our rate limiter was not actually rate limiting anything.
