Senior Software Engineer | Full Stack Senior .NET Developer with over 20 years of experience in both greenfield and brownfield development, designing, developing, and optimizing complex, scalable applications across legal, healthcare, government consulting, retail workforce management, benefits administration, and programmatic media advertising. Proven ability to lead teams, mentor developers, and implement solutions for complex systems while adhering to best practices and modern design patterns
I’m a backend .NET developer with 7 years of experience in SCRUM, Azure DevOps, Git, .NET and C#. I strive to be a trusted reference in development and software design, sharing best practices and driving the creation of robust, scalable solutions.
I’ve been writing code for over 17 years, growing into roles like Principal Engineer and Java Technical Lead. I’ve helped non-developers turn their dreams into developer careers, supported juniors at the start of their journey, and mentored entire teams. I approach mentoring with kindness, precision, and attention to detail—and problems tend to shy away when I’m around.
I mentor programmers and development teams. I have the skill set to get you out of any development problem. That includes but not limited to: Java, C#, .NET, JavaScript, TypeScript, Python, Spring, Angular, React, and Agile methodologies. I have a focus on writing "clean code", secure coding, and identity management (SAML 2.0 & OAuth 2.0).
I'm a passionate software developer always looking for new challenges. I have the guidelines in my life. 1. It's not a shame not to know something, but not wanting to learn. 2. Knowledge is useless if not shared 3. Always prioritize quality, but be reasonable
