What I'm looking for

I am seeking a role that fosters innovation and collaboration, with opportunities for growth and impactful projects.

I'm a Staff Software Engineer with over 12 years of experience in healthcare, observability, and fintech startups. My journey has been marked by significant achievements, including leading the development of Sydney Health at Elevance Health, a cloud-native digital health platform that serves 16 million users. I have successfully implemented AI-driven solutions that have facilitated 1.5 million secure telehealth visits, showcasing my ability to leverage technology for impactful healthcare solutions.

At Datadog, I optimized data pipelines for over 28,000 customers, achieving an impressive 99.99% uptime. My expertise in building secure fintech APIs at Itexus led to a 40% reduction in unauthorized access incidents. I thrive in fast-paced Agile environments, where I mentor junior engineers and streamline deployments while ensuring compliance with HIPAA and PCI DSS standards. My technical proficiency spans a wide array of technologies, including Java, Python, AWS, and Kubernetes, allowing me to architect robust solutions that drive efficiency and enhance user experiences.
