What I'm looking for

I seek senior engineering roles focused on building cloud-native, scalable systems with strong DevOps collaboration, opportunities to mentor, and measurable performance and reliability improvements.

I am a seasoned Full Stack Engineer with 8+ years building scalable web applications using C#, ASP.NET Core, Angular, TypeScript, and SQL Server. I design microservices architectures, optimize RESTful APIs, and deliver responsive front-end experiences while collaborating closely with DevOps, QA, and product teams to produce secure, maintainable software.

At Qumulo and DocuSign I led API modernization, performance tuning, and CI/CD adoption, cutting query times dramatically and reducing technical debt while mentoring junior engineers. I focus on measurable outcomes—faster load times, reduced CPU usage, improved test coverage—and I prioritize clean architecture, security (OAuth2/OpenID Connect), and accessibility in every delivery.
