Three trainings, one principle: always-current material
Built and maintained at release pace thanks to an automated daily intelligence pipeline — not vintage slides reheated for two years.
AI & LLMs for developers
The foundation — prompting, APIs, RAG, agents. 2 days, ~55% hands-on.
Claude Code
The augmented developer — CLAUDE.md, MCP, subagents, hooks, CI/CD. 2 days, ~75% hands-on.
Agentic coding for teams
Copilot, Agent HQ, Codex — deploying and governing coding agents at team scale. 1.5 days, ~70% hands-on.
On-site (intra), on quote. Every session opens with a responsible AI / AI Act module, and the tracks prepare for official certifications (GitHub GH-300, Anthropic certifications).
Proof through the pipeline
The weekly newsletter is produced by the same intelligence pipeline that keeps the trainings current. Judge the curation for yourself:
Strict curation
Out of 200 AI announcements per week, we keep 5. The right ones.
5 minutes per week
The 5 major AI news, summarized and analyzed. Not 50.
By a dev who codes every day
No marketing hype. Concrete tools, real versions.
Checked before publication
Every number, date and quote is cross-checked against its source before sending. Anything that doesn't hold up is dropped.
Who is behind Zarev?
Hi, I'm Sébastien. Freelance developer — I code every day with Claude Code, MCP, agents and the whole AI ecosystem moving at 200 km/h. Zarev is two sides of the same work: the daily intelligence that keeps me sharp, and the trainings where I pass it on to dev teams.
Zarev — "rev" as in "rev up", leveling up your dev game.
