- Style: Interactive and hands-on — not a slide deck
- Customized: Tailored to your team's codebase and objectives
- Led by: The people who built and maintain the Critter Stack
Topics We Cover
The Critter Stack
Comprehensive introduction to Marten, Wolverine, and the rest of the ecosystem. How the tools work together and where each one fits.
Event Sourcing
Designing event-sourced systems, projections, snapshots, versioning, and the common pitfalls teams encounter in real-world implementations.
CQRS Patterns
Command Query Responsibility Segregation patterns with Wolverine and Marten — from simple to advanced, with practical guidance on when and how to apply them.
Asynchronous Messaging
Reliable messaging with Wolverine — message routing, error handling, retries, dead letter queues, and integration with external brokers.
Automated Testing
Testing strategies for event-sourced and message-driven systems. Integration testing with Alba, test-friendly architecture patterns, and TDD approaches.
Production Readiness
Observability, monitoring with CritterWatch, performance tuning, multi-tenancy, and operational best practices for Critter Stack applications.
Who Should Attend
Our workshops are designed for .NET development teams at any stage of their Critter Stack journey:
- New adopters — teams evaluating or beginning to use Marten, Wolverine, and related tools
- Growing teams — developers who need to deepen their understanding of Event Sourcing and CQRS patterns
- Experienced users — teams looking to optimize their architecture, improve testing, or tackle advanced scenarios
What Our Clients Say
"Jeremy's Critter Stack workshop didn't just level up the team that attended it — the recording became day-one material for every new developer who's joined since. Hard to find engineering training that's still paying dividends two months later."
— EVP Engineering, Filevine
