Owain Lewis – AI Engineer

Here’s What You Get:

Overview

Owain Lewis – AI Engineer is a membership program created by Owain Lewis, a software engineer with over 20 years of experience and founder of Gradient Work. The program focuses on teaching developers how to build production-quality AI applications and AI agents using sound engineering principles rather than relying on hype or tool-specific tutorials.

The philosophy behind the program is simple: Tools change. Principles don’t.

Instead of teaching shortcuts, the course emphasizes engineering judgment—understanding when AI-generated code is reliable, how to design robust systems, and how to ship software that works in real-world environments.

What’s Included

1. Agentic Engineer

A flagship course covering professional AI-assisted development with tools such as:

• Claude Code
• OpenAI Codex
• Cursor
• GitHub Copilot
• Other AI coding agents

Topics include:

• Planning before coding
• Spec-driven development
• Reviewing AI-generated code
• Debugging and testing
• Building custom agents
• Shipping production-ready applications

Students complete practical projects rather than toy examples.

2. AI Architect

Focused on designing and deploying AI systems.

Key subjects include:

• AI agents
• Retrieval-Augmented Generation (RAG)
• Evaluation and monitoring
• Cloud deployment
• Python backends
• Next.js frontends
• Production architecture

A capstone project guides members through building a document question-answering agent using their own data.

3. Skills Vault

A growing library of practical resources:

• Prompt templates
• CLAUDE.md configurations
• AGENTS.md examples
• Planning frameworks
• Review checklists
• Deployment templates
• Reusable workflows

The library is updated as AI tooling evolves.

4. Monthly Live Builds

Owain hosts monthly workshops where he:

• Builds applications live
• Demonstrates engineering decisions
• Answers questions
• Shows production workflows

Recordings remain available to members.

5. Community and Support

Membership includes:

• Access to a community of builders and engineers
• Peer collaboration
• Direct asynchronous access to Owain
• Feedback and troubleshooting support

Current community size is around 120+ members.

Core Topics Covered

• AI coding workflows
• Agentic engineering
• Software architecture
• Python and TypeScript
• APIs and databases
• AI agents
• Tool calling
• RAG systems
• Prompt engineering
• Evaluation frameworks
• Debugging AI-generated code
• Automation
• Deployment and cloud infrastructure
• Production engineering practices

Who It’s For

Ideal For

• Software developers
• AI engineers
• Technical founders
• SaaS builders
• Automation consultants
• Engineers already using Claude Code or Codex
• Professionals wanting to build production AI systems

Less Suitable For

• Complete beginners with no programming experience
• People seeking no-code AI tutorials
• Those wanting only prompt engineering instruction
• Users looking for quick “make money with AI” methods

Main Outcome

By completing AI Engineer, members learn how to:

• Work effectively with AI coding agents.
• Build and deploy real AI applications.
• Design scalable AI systems.
• Develop engineering judgment rather than tool dependency.
• Transition from simply writing code to architecting AI-powered software systems.

Summary

Owain Lewis – AI Engineer is a membership-based training program that teaches the craft of AI-assisted software engineering. Through the Agentic Engineer and AI Architect flagship courses, live workshops, and a growing Skills Vault, members learn how to build reliable AI applications and become AI-first engineers capable of shipping production-quality systems. It is particularly valuable for developers and technical builders who want to move beyond tutorials and master the principles behind modern AI engineering.
