Mairu | Lambda Script

Lambda Script is a channel about building useful software in the age of AI.

I’m a Japanese software engineer documenting the real process of building AI products after work: ideas, code, launches, mistakes, early users, and everything that happens between them.

On this channel:
- Building AI products, SaaS, and solo projects in public
- Real-world experiments with Claude, Codex, AI agents, and developer tools
- Product decisions, launches, marketing, and finding early users
- What it takes to turn code into a product people actually use
- Honest lessons from the constraints, costs, and failures along the way

Not polished success stories. Real experiments.

Return True.
