I build, fix, and improve complex business applications using .NET, React, and SQL. With 12+ years of experience, I help businesses build new SaaS applications, extend existing systems, solve difficult technical problems, and modernize applications that have become difficult to maintain. I don't just implement tickets. I try to understand the underlying problem, identify the root cause, and deliver a solution that is reliable and maintainable.
