# Vibengineer > Production foundations for founders building with AI. Vibengineer is the consulting practice of Sébastien Vanson, a senior engineer with 11+ years of experience shipping production software. He helps founders who build products with AI tools (Cursor, Bolt, Claude Code) get their apps production-ready — with proper architecture, auth, CI/CD, deployment, and monitoring. ## What Vibengineer Does AI tools build features fast, but they don't give you a reliable product. Vibengineer bridges the gap by setting up the engineering foundations that make an AI-built product stable, scalable, and launchable. Core deliverables: - **Architecture** — Clean, scalable project structure - **Auth** — Signups, logins, and access control that work - **Data** — Reliable data layer and database setup - **CI/CD** — Automated testing and safer deployments - **Monitoring** — Visibility into errors and performance - **AI workflow** — Keeping AI tools productive long-term ## How It Works 1. **Discovery** — Code review and prioritized action plan 2. **Setup** — Build the foundation (auth, data, deployment) 3. **Build & Maintain** — Ongoing support as features are added ## Pricing - **Audit** (€1,500, ~3 days) — Code review, report, and investor-ready docs - **Starter Stack** (€5,000, ~2 weeks) — Foundation setup: auth, data, deployment - **Pro Stack** (€10,000, ~3-4 weeks) — For complex products, includes architecture rework - **Maintenance retainers** — Light (€800/mo) or Active (€1,500/mo) ## About Sébastien Vanson is a senior software engineer with 11+ years of production experience.
