Senior Software Engineer specializing in secure healthcare data platforms, integrations, and implementation delivery.
What I'm looking for
I am a results-driven Senior Software Engineer with 9+ years delivering secure healthcare and enterprise data platforms, focusing on data auditing, file transformation, system integration, testing, and customer-facing implementation workflows in regulated environments.
I have led technical execution for employer eligibility and enrollment implementations, improving first-pass accuracy, reducing escalations, and shortening implementation cycles by building repeatable validation and reconciliation workflows using Python, SQL, C#, and Azure Functions.
My work spans building configurable integration layers, validating complex enrollment logic, and producing SOPs and training to raise team consistency and throughput; I routinely translate technical integration details into clear guidance for operations, vendors, and business stakeholders.
I hold cloud and platform certifications (AWS, GCP, CKA, DCA) and seek to continue improving data quality, automation, and audit readiness while mentoring teammates and supporting customer success in sensitive, compliance-driven environments.
