From over 13 years, I’m creating software close to the business. I started my career when StackOverflow didn’t exist. I’m a developer, technical leader and architect.

I like building well-designed systems, tools and frameworks that are used on production and making the people’s life easier. I believe that using Event Sourcing, CQRS, and in general, Event-Driven Architecture are the good foundations to achieve that. Working on OSS and knowledge sharing is the huge motivation driver for me.

That’s why I am:

• running workshops and training about Event Sourcing, CQRS and event-driven architectures.
• co-maintainer of Marten OSS library that allows implementing Event Sourcing.
• providing Event Sourcing in real-world samples and tutorials in my Github Repository
• share my knowledge on the blog of how to create good, modular applications pragmatically.

My main projects:

• 🐿️ Marten - .NET Transactional Document DB and Event Store on PostgreSQL - https://martendb.io/.
• ⚡ Event Sourcing in .NET - Practical samples, self-paced kits and tutorials of how to build Event-Sourced applications in .NET.
• 🔧 WebApi with .NET Core - Samples and resources of how to create well-designed WebApi in .NET.
• 👁️ GoldenEye - The CQRS flavoured framework that will speed up your WebAPI and Microservices development.
