What I'm looking for

I’m looking for a senior role where I can build secure full-stack C#/.NET systems and AI-powered features, working in Agile teams on real-world healthcare or fintech problems with strong engineering practices.

I’m a full-stack C#/.NET engineer with 7+ years of hands-on experience delivering web applications, RESTful APIs, and enterprise systems across healthcare, financial services, and AI. I thrive in fast-paced Agile teams, translating complex requirements into secure, reliable software.

I’ve built and modernized production systems with strong compliance requirements, including HIPAA- and PCI-DSS-compliant implementations. In healthcare work, I enforced HIPAA controls like TLS 1.3, field-level encryption, and automatic PHI audit logging.

On the AI and communications side, I’ve delivered voice and AI-powered workflows—integrating telephony with systems like Twilio Programmable Voice and Azure Communication Services, and deploying scalable serverless processing on AWS. I also develop AI applications using OpenAI-powered capabilities and distributed pipelines for research and analysis.

I bring a product-minded engineering approach: from financial reporting and payroll automation to data migration utilities with validation and transactional integrity, and from internal tooling to customer-facing SaaS. I’m energized by complex problem-solving across backend, data, and user experience—always with security and maintainability at the center.
