Stop handing over designs. Start building them.
Master the end-to-end workflow of top Design Engineers.
Design Track
For engineers. Learn typography, colour, and layout. Develop the design taste to ship interfaces you're proud of.
Engineering Track
For designers. Go beyond Vibe Coding and actually understand HTML, CSS, and JavaScript. Build it yourself.
Convergence: All-Access
Starting your career, or want both skillsets? Everything included, plus exclusive content on motion, prototyping, and accessibility.
Our Approach
Text-based. Interactive. Effective.
No hour-long videos. Concise written lessons with embedded exercises, questions, and hands-on practice. Research shows this format works best for learning technical skills.
- Watch → forget
- Linear, hard to skim
- Mind wanders during playback
- Read → do → remember
- Searchable, skimmable, scannable
- Questions keep you engaged
Active over passive
Each lesson embeds questions, exercises, and reflections. You think and apply, rather than passively watch.
Your pace, your control
Skim what you know, linger on what's tricky, jump to what you need. Text gives you control that video can't.
Retention through doing
Short explanations followed by exercises reduce mind wandering and boost long-term retention.
Reference-friendly
Search, bookmark, and revisit specific concepts. Text becomes a lasting resource, not a one-time watch.

Your Instructor

Karl Koch
Design Engineer with over a decade of experience shipping interfaces across web, iOS, and Android. Previously at startups and agencies, now at DuckDuckGo.
This course exists because Design Engineering is too often learned the hard way through years of trial and error, scattered blog posts, and outdated tutorials. Every module is built from real-world experience shipping production products, not academic theory.
