About Simo Roikonen

LinkedIn Bluesky

Simo is a seasoned software crafter, solution architect, and communicator, with a deep commitment to building evolvable, long-lasting backends. With over a decade of experience in Domain-Driven Design, Simo excels at transforming complex problems into clear, actionable solutions. When systems require scaling and resilience, he brings a proven track record in distributed architectures and scalability, delivering low-latency at any scale.

Beyond the technical aspects, Simo understands that successful software development & high development velocity thrives in a balanced sociotechnical environment. He values collaboration and brings stakeholders together to ensure smooth progress, whether it’s a modernization effort, greenfield project, or eliminating bottlenecks in existing systems. Simo is adept at crafting solutions that meet both technical and organizational needs, ensuring systems that are robust, scalable, and future-ready.

System Modernization

Simo has extensive experience in modernizing complex, large-scale systems — a process that involves not only experimenting, organizing, and communicating, but also leveraging modern technologies and architectures. Modernization, in Simo’s view, is a sociotechnical exercise where he has consistently served as a hands-on technical leader.

Removing Bottlenecks

Bottlenecks should only exist for a purpose. While unwanted bottlenecks can often be addressed through optimization, he recognizes that more robust solutions, like horizontal scalability and distribution, are frequently necessary to achieve sustainable growth and performance.

Domain-Driven Design

In complex domains achieving both high quality and development velocity depends on creating a shared language that everyone — from developers to stakeholders — can understand. This alignment is the secret sauce of success, as building complex systems is, at its core, a process of communication.
