What I'm looking for

I am seeking senior engineering roles focused on cloud-native platform and backend systems where I can drive scalable, secure architectures, mentor engineers, and collaborate cross-functionally in an Agile environment.

I am a Senior Software Development Engineer with over 10 years building scalable, secure, and compliant cloud platforms across healthcare, e-commerce, and enterprise domains. I architect low-latency APIs, distributed microservices, and petabyte-scale data pipelines while ensuring regulatory compliance such as HIPAA and PCI-DSS.

At Amazon I engineered sub-second medical image retrieval, implemented petabyte-scale DICOM ingestion pipelines, and enforced encryption and audit logging standards, while contributing to developer documentation and mentoring engineers. Previously I built PCI-DSS–compliant checkout APIs and real-time fraud detection at Deliverr, and developed integration and observability solutions at Informatica.

I enjoy collaborating with cross-functional teams, improving developer productivity through CI/CD and IaC best practices, and delivering enterprise-grade solutions that meet performance, security, and regulatory requirements.
