What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

As a Senior Software Engineer with over 10 years of experience, I specialize in backend and full-stack development, focusing on scalable, cloud-native applications. My expertise spans multiple programming languages, including Java, Node.js, PHP, Python, C++, C#, and Go. I have a proven track record of architecting and developing secure and efficient digital health platforms and e-commerce solutions.

At Labcorp, I led the development of the Labcorp OnDemand digital health platform, ensuring HIPAA compliance and high availability through microservices deployed on AWS. My role involved designing robust APIs, optimizing database performance, and implementing CI/CD pipelines to enhance system observability and rapid delivery. My previous experience at Live Action further honed my skills in building backend services and integrating advanced authentication mechanisms.

I am passionate about leveraging my technical skills and engineering leadership to drive innovation and deliver high-quality software solutions. I thrive in Agile environments and am committed to continuous improvement and collaboration within teams.
