New Course — 2026

From Vibe Code to Production SaaS

You built it with AI. Now make it unbreakable. The complete architecture guide for developers who ship with Claude Code, Cursor, and Copilot — but know their codebase needs more than “it works.”

AI writes code. Nobody teaches what’s missing.

What AI tools won’t tell you
  • Your JWT tokens are stored in localStorage
  • You have no CSRF protection
  • Your database has zero migration files
  • Multi-tenancy is an afterthought
  • One webhook failure could lose a payment
  • You have no disaster recovery plan
What this course teaches
  • Production-grade auth with httpOnly cookies
  • Security middleware from day one
  • Database migrations, indexing, and scaling path
  • Multi-tenant architecture that isolates data
  • Idempotent webhooks and circuit breakers
  • Monitoring, backups, and runbooks

Four builders. One missing piece.

The Vibe Coder

You shipped something real with AI tools. It works. But you know the architecture is held together with duct tape.

🎓
The Bootcamp Grad

You can build CRUD apps. But you’ve never dealt with multi-tenancy, payment processing, or compliance at scale.

🚀
The Indie Hacker

You have paying customers or you’re close. Nobody talks about what happens when your database hits 200 concurrent writers.

🔄
The Career Switcher

AI made it possible for you to build real apps. Now you need the systems engineering foundation to make them last.

14 modules. Zero filler.

Every module uses a real 93K-line SaaS as its case study. Architecture diagrams, code snippets, before/after comparisons — illustrated through a system complex enough to make the patterns real.

00
The AI-Powered Development Workshop
Claude Code deep-dive, prompting strategies, toolchain comparison, the vibe coding workflow that produced 93K lines
01
SaaS Architecture Fundamentals
Monolith-first design, domain-driven layout, 12-Factor principles, tech stack decision framework
02
Authentication & Security
httpOnly JWT cookies, CSRF protection, rate limiting, input sanitization, Content Security Policy
03
Database Design for Production
Schema design, migrations from day one, indexing, multi-tenant isolation, SQLite-to-PostgreSQL path
04
API Design That Developers Respect
Versioning, pagination, error responses, rate limiting per tenant, OpenAPI documentation
05
Multi-Tenancy
One app, many customers — data isolation, tenant-aware middleware, shared vs. siloed strategies
06
AI Integration for Production
LLMs as external APIs, dual failover, cost management, prompt versioning, graceful degradation
07
Third-Party Integrations
Adapter pattern, circuit breakers, idempotent webhooks, payment processors, email services
08
Frontend Architecture for SaaS
Component patterns, state management, tenant-aware UI, responsive dashboards, accessibility
09
Production Infrastructure & DevOps
Docker, Nginx, PM2, CI/CD pipelines, SSL, VPS vs cloud vs PaaS decision framework
10
Monitoring, Logging & Reliability
Structured logging, health checks, alerting, error tracking, uptime monitoring, incident response
11
Legal & Compliance
GDPR, Mexico’s LFPDPPP, CCPA, PCI DSS basics, Terms of Service, privacy policy essentials
12
SEO, Growth & Website Best Practices
Technical SEO, landing page optimization, JSON-LD structured data, analytics, conversion funnels
13
Scaling to 10,000 Users
Performance profiling, caching strategies, database optimization, horizontal scaling, cost modeling

After this course, you will

Architect a multi-tenant SaaS from scratch using a monolith-first approach that scales to microservices when needed
Implement production-grade security — httpOnly cookies, CSRF, rate limiting, CSP headers, and input sanitization
Design database schemas that handle real-world complexity with migrations, indexing, and a documented scaling path
Build APIs that developers respect — versioning, pagination, error responses, rate limiting per tenant
Integrate third-party services defensively with adapters, circuit breakers, and idempotent webhooks
Deploy and operate production infrastructure — Docker, CI/CD, monitoring, backups, and disaster recovery
Navigate legal and compliance — GDPR, LFPDPPP, CCPA, PCI DSS, Terms of Service
Audit any vibe-coded project using a systematic checklist covering security, architecture, and operational readiness

Not a tutorial. A production playbook.

Three things make this different from every other “build a SaaS” course.

01
Real case study

Built on a real 93,000-line production SaaS — not a tutorial todo app. Every pattern comes from a system serving real businesses.

02
Teaches the gaps

AI assistants generate code. They never suggest what’s missing — CSRF protection, migrations, disaster recovery, compliance. This course is that checklist.

03
Built by a shipper

Not a developer advocate who built a demo. By a solo developer who went from zero to 93K lines of production code and documented every wall.

AI Solutions Engineer — Mexico City

Solo-built a 93,000-line AI-powered SaaS using Claude Code over 8 months. Automated 3 service lines across 8+ platforms. Now teaching the architecture patterns, security practices, and operational knowledge that AI tools never suggest — because nobody prompts for what they don’t know they’re missing.

Common questions

Do I need to know a specific programming language?
The course uses JavaScript/Node.js for examples, but the architecture patterns are universal. If you can read code and have built at least one web app — with or without AI — you’ll be able to follow along and apply everything to your own stack.
Is the RoboFood source code included?
No. RoboFood is used as a case study through architecture diagrams, code snippets (10-30 lines), file tree structures, and before/after comparisons. The full source code stays private. You’re not here to copy — you’re here to learn the universal patterns.
What if I’m just starting to build my SaaS?
Even better. Every module includes exercises you apply to your own project. Starting with the right foundations from day one is exactly what this course teaches — it’s the knowledge that could cut 8 months of development down to 3.
How is this different from free YouTube tutorials?
Tutorials teach you how to build features. This course teaches you everything tutorials leave out: security, compliance, multi-tenancy, operational readiness, disaster recovery. The stuff that matters when real users are paying you real money.
What’s in the SaaS Starter Template?
A production-ready boilerplate with authentication, multi-tenancy, billing integration, database migrations, CI/CD configs, Docker setup, monitoring, legal page templates, and deployment scripts. Everything pre-configured so you start at Module 1’s finish line.
Do I get lifetime access?
Yes. One-time purchase, lifetime access, including all future updates and additions to the course content.

Stop shipping duct tape.
