Tool Use - AI Conversations Build A Full Stack App With One Prompt (ft. Richard Abrich)
Sep 9, 2025
Richard Abrich, an AI consultant and the creator of Fastable, shares his insights on building full-stack apps from just one prompt. He discusses the power of Fastable's tech stack, including FastAPI and Postgres, as a flexible alternative to traditional tools. Richard dives into context engineering, AI hallucination mitigation, and the innovative use of logging to speed up development processes. The conversation also touches on the future of disposable software and how AI is reshaping application development, making coding more accessible for everyone.

Episode notes
Log-Driven Origin Story
- Richard built Fastable after integrating logs into the coding loop to automate tedious copy-paste debugging.
- He created Fastable to pipe runtime logs into agents so generated code can self-fix faster.
Vanilla Tech Stack Advantage
- Fastable intentionally uses a vanilla stack: FastAPI, Python, React, Postgres and Docker.
- That choice targets developers who want control and to avoid Supabase lock-in.
Create A Design Pre-Prompt
- Use a pre-prompt design assistant to convert vague ideas into precise, reusable design docs before coding.
- Keep a shared context document to move between conversations and avoid garbage-in prompts.
