01 /The starting point

What needed to change.

Our client, an established B2B SaaS company with more than 150 employees, faced significant challenges with its aging technology platform. Developed more than 10 years earlier, the platform used a monolithic architecture and outdated technologies, resulting in long development cycles and frequent outages.

Scalability was severely limited, leading to performance problems as user numbers grew. The technology team also worked in a fragmented way, without clear processes. The company recognized the need for comprehensive modernization to remain competitive and enable future growth.

02 /Our contribution

How we approached it.

We took on interim technology leadership as CTO and coordinated the transformation with a strategic view. Following a comprehensive analysis, we developed a modernization strategy with clear priorities and a target architecture designed for future needs. A carefully developed migration plan minimized business disruption during the transition.

The technical work covered three core areas: gradual migration from the monolith to a flexible microservices architecture, implementation of scalable cloud infrastructure with automated load balancing, and modern engineering practices including CI/CD and automated testing. A robust monitoring system enabled proactive responses to potential problems and significantly improved availability.

Alongside the technical transformation, we reorganized the technology team. We defined clear roles and responsibilities, introduced agile development methods and provided comprehensive training. A new governance framework supported innovation while maintaining consistency and quality. Together, these changes created a solid foundation for future growth and innovation.
