What I'm looking for

I seek senior backend or systems roles where I can architect scalable solutions, modernize legacy systems, mentor teams, and work with robust databases and networking protocols.

I am a highly skilled senior software developer with over 20 years of experience building backend systems, databases, and integrations using C, C++, C#, .NET Core, Java, and Python. I have designed and administered databases (Microsoft SQL, Oracle, MySQL), delivered many REST APIs and protocol integrations, and led small development and DBA teams to deliver production-grade solutions across telecom, RAN, and enterprise projects.

I have a strong track record of modernizing legacy systems, implementing security and networking features (IPsec, L2TP, IPv6), teaching applied courses in Python and data visualization, and producing reliable reporting solutions with Crystal Reports. I bring leadership, pragmatic problem-solving, and a commitment to high-quality, maintainable software.
