Jargonaut: Dev Vocabulary

Jargonaut teaches the vocabulary of software engineering. Learn dev terms through short daily missions with clear definitions, analogies and quick quizzes.

WHAT YOU'LL LEARN
Build fluency across 8 domains of engineering:
- Architecture: microservices, monoliths, system design, scalability
- Code Craft: SOLID, TDD, refactoring, testing, debugging
- Data & Storage: databases, indexing, caching, transactions, NoSQL
- DevOps: CI/CD, containers, infrastructure as code, monitoring
- AI/ML: machine learning, neural networks, recommendation systems
- Plus Networking, Security and Team Process

HOW IT WORKS
- Learn one concept per mission in five steps: the term, what it means, an everyday analogy, how it's used in the real world, then a debrief quiz.
- Answer multiple-choice, fill-in-the-blank, matching and scenario questions with instant, explained feedback.
- Choose your track when you start - "I'm a developer" or "I work with developers" - and get examples tailored to your role.

STAY CONSISTENT
- Keep a daily streak and level up your rank from Cadet to Jargonaut by earning Signal points.
- Collect Bronze, Silver and Gold badges in each domain.
- Reinforce what you've learned with word games such as Hangman.

WHO IT'S FOR

- Bootcamp graduates and students preparing for interviews.
- Product managers, designers and founders who collaborate with engineering teams.
