DataTalks.Club (Alexey Grigorev and Bhavani Ravi)·GitHub
Free
A free community course on building and shipping software with AI coding agents: spec-driven workflows with AGENTS.md, an AI-assisted full-stack app, testing and containerized deployment, observability, and agent building blocks like SKILL.md skills, subagents and parallel Git worktrees. It suits working developers who want an engineering-grade, project-based alternative to vibe-coding tutorials, with an optional cohort for accountability.
