I built 9 AI agents that forgot everything between conversations—wasting users 20-45 minutes weekly re-explaining their business. Here's how I made them share memory.

I shipped team collaboration features in alpha with <50 users because my customers were already working in teams—just through painful screenshots and copy-paste workarounds that cost 80+ hours per year.

I discovered my Postgres database had 89 foreign keys but zero indexes on them—turning millisecond queries into 843ms nightmares and nearly killing my alpha launch.

I found 31 blank screens in my SaaS—all because I forgot multi-tenancy isn't just about data access, it's about URL context. Here's how Claude Code helped me fix them all in one night.

I thought adding org_id to every table meant bulletproof multi-tenancy. Then my security audit revealed agencies were writing to SME tables—not through a bug, but by design.

After 20 years in agencies, I knew multi-tenant architecture couldn't wait—so on Day 2, with just one working AI agent, I tripled my dev complexity to avoid a future rewrite.

I fed my own landing page to my AI strategy agent and rebuilt it in 24 hours—conversion messaging transformed by dogfooding the product I'm selling.

I built a 9-agent marketing platform in 75 days that learns from every conversation—tell one agent about your business, and all nine get smarter together.

I spent 24 hours debugging why my React app kept making HTTP requests from HTTPS pages—even though my code was converting them. The culprit shocked me.

I built 3 AI marketing agents with multi-tenant architecture in 4 weeks—the same amount I accomplished in a month building my previous product that took 7 months to launch.

I almost shipped a major TTS engine swap by just "hoping for the best"—until my AI assistants flagged the risks and helped me build a bulletproof feature flag strategy instead.

I hunted down a 3-minute signup delay that turned out to be Schrödinger's user—existing and not existing at the same time due to database replication lag between writes and reads.
