Nicholas Blumhardt

Nationality: Australian

Nicholas Blumhardt is the creator of Serilog, the popular structured logging library for .NET, and a founder of Datalust (the company behind Seq, a powerful log analysis tool).

Hailing from Australia, Nicholas has long been an open-source trailblazer in .NET – he also initiated the Autofac dependency injection container back in 2007 (one of the first IoC containers for .NET). As a former program manager at Microsoft (years ago), he helped shape parts of .NET, but his passion clearly lies in building tools that developers love. Serilog introduced the idea of “structured logging” to the .NET world, and its rich ecosystem of sinks and enrichers is a testament to Nicholas’s focus on extensibility.

In 2025, he maintains Serilog (which recently hit version 3.0 with new features) and actively engages with the community via GitHub and Mastodon. Nicholas’s influence on how C# applications are built (with proper logging and DI practices) is immense and ongoing.

Jeremy D. Miller

Nationality: American

Jeremy D. Miller is a veteran software architect and the original author of StructureMap, the first widely used dependency injection container for .NET (dating back to 2004).

Jeremy has a passion for architectural patterns and clean code, which he’s demonstrated through his open-source projects over the years. He leads the development of JasperFX libraries – notably Marten (a Postgres-based document database and Event Sourcing library for .NET) and Wolverine (a next-generation background job and messaging framework). These projects push the envelope of what can be done with C# in terms of efficiency and design elegance. Jeremy runs his own company (JasperFX) and consults for enterprise clients, while maintaining an active blog “The Shade Tree Developer” where he shares the lessons learned from real-world systems.

In 2025, Jeremy’s projects Marten and Wolverine are gaining wider adoption in the .NET community for building scalable systems, and he continues to refine them (releasing regular updates and engaging on GitHub). His long-term commitment to improving the .NET ecosystem through open source makes him a standout figure.
