Build an Unusual Options Activity Scanner With Python and Free Data

Last month I noticed something odd: SMCI options volume spiked to 8x its 20-day average on a random Tuesday afternoon. No news. No earnings. Three days later, the stock jumped 14% on a surprise partnership announcement. Someone knew. Unusual options activity (UOA) — when volume on a specific contra...

How I'd Design a Memory System for an AI Companion App

I spent 200 days testing 15 AI companion apps. Paid for every subscription myself. Talked to each one for weeks, sometimes months. The single biggest thing separating the good ones from the bad ones?

Your AI Stack Is Too Big

We hit this hard during a production rollout: response times spiked, and user engagement tanked. Everyone assumed we needed a bigger model. We were wrong. Performance wins almost always come from architecture, not model size. Your users feel the delay long before they read your roadmap. If you're d...

Adding Multi-Agent Orchestration to a Vercel AI SDK App

I hit a wall recently. I had a working AI SDK app -- streamText, useChat, the whole thing -- and then I needed it to do something that a single agent can't: research a topic with one agent, then hand that research to a second agent for writing. You can do this manually. Glue two generateText calls...

Feature flags that show you how your rollout is actually performing

Most feature flag tools tell you whether a flag is on or off. They don't tell you if it's actually working. You deploy a flag, start rolling it out to users, and then... what?
