FirstFocus was trapped in a vicious cycle - 70% of their developers' time went to maintaining legacy .NET Framework code instead of building features. Projects that should take weeks stretched into months. They were losing talented developers who didn't want to work on outdated technology, and client satisfaction was dropping.
FirstFocus came to me with a classic Legacy Lock-In problem: 70% of their development team's time was spent maintaining outdated .NET Framework code instead of building features that would grow their business. Their talented developers were frustrated, clients were experiencing delays, and the company was losing competitive edge.
This wasn't just a technical migration - it was a complete transformation of their development culture. Over four years, we systematically migrated from .NET Framework to modern .NET Core while building a scalable team structure. I established CI/CD pipelines that reduced deployment times by 90% and created mentorship programs that doubled team productivity.
The real challenge was managing this transformation while continuing to deliver client projects. We built and integrated a 7-person offshore development team, ensuring knowledge transfer and maintaining quality standards throughout the scaling process. Every decision was made with long-term sustainability in mind.
The results speak for themselves: FirstFocus went from struggling with legacy maintenance to delivering €100K+ in client projects while doubling their team size. They transformed from a company held back by their technology to one empowered by modern development practices and scalable architecture.
