What I'm looking for

I am looking for a role that fosters innovation and collaboration, with opportunities for growth and leadership in software development.

As a Principal .NET Engineer, I have a proven track record of architecting robust software solutions that drive efficiency and innovation. At Paylocity, I led the development of a suite of payroll microservices, leveraging ASP.NET Core and event-driven architectures to enhance tax calculations and payment processes. My experience with CQRS and domain-driven design has enabled me to create scalable applications that meet complex business needs.

Previously, I contributed to Expedia Group as a Senior Software Developer, where I designed backend flight pricing APIs and implemented resilient data ingestion architectures. My technical skills extend to integrating third-party services and optimizing performance through strategic use of caching and SQL tuning. I am passionate about maintaining high standards of code quality and security, as demonstrated by my work in auditing APIs and implementing CI/CD pipelines.

With a strong foundation in computer science and extensive experience in software development, I am committed to continuous learning and applying best practices in software engineering. I thrive in collaborative environments and am eager to tackle new challenges that push the boundaries of technology.
