Problems I solve

When business software works, but starts holding the company back.

Many companies do not need to rebuild everything. They need a clear technical diagnosis, progressive modernization and practical improvements that protect daily operations.

Legacy .NET applications that are hard to maintain
Slow SQL Server queries and weak database design
Manual reports, Excel dependency and duplicated processes
Difficult integrations with ERP, POS or external APIs
Manual deployments, poor environment configuration and production issues
Teams that need senior .NET support without a full-time hire
