Consultation & Trainings

How can I empower you?


I guide teams to enhance their capabilities, develop efficiently on the .NET platform, and utilize available tools. I help bridge the gap from basic programming to sophisticated software development, and from development practices to architectural design, focusing on building sustainable software solutions.


Sometimes, an external perspective is crucial. Do you want to avoid tunnel vision? Are you certain that conventional methods are the best approach for your project? Let's explore innovative solutions together.

Architecture Review

I assist in designing your application's architecture and selecting the most suitable technologies to meet both current needs and future scalability.

Application Modernization

Dealing with an older legacy application that's accumulated substantial technical debt, yet a full rewrite isn't feasible? Consider integrating modern technologies for new components to gradually improve the system.

Performance Optimization

Is your application experiencing slow performance, memory leaks, or stability issues? I specialize in enhancing the performance, reliability, and overall health of software applications.

Emergency Intervention

Is your project in crisis? I provide immediate support and strategic solutions to rescue and turn around troubled projects.
