What I'm looking for

I’m looking for a remote-first Agile team where I can build secure, observable serverless full-stack systems on AWS—especially for regulated healthcare use cases—owning backend design, compliance, CI/CD, and mentoring for long-term impact.

I’m a Senior Software Engineer with 11+ years in cloud-based full-stack and serverless application development. I focus on scalable Node.js and TypeScript systems and the security/compliance work that regulated products require.

I’ve delivered event-driven architectures supporting 500K+ users while protecting PII and aligning with HIPAA, GDPR, and GDPR-related controls. My work often centers on Identity and Security (OAuth2, JWT) and secure API design, backed by SOC 2-ready practices.

On AWS, I design and operate solutions with Lambda, API Gateway, and DynamoDB—especially DynamoDB single-table design using partition/sort keys and TTL strategies. I also provision infrastructure as code with AWS CDK and CloudFormation, and I improve reliability and observability with CloudWatch dashboards, alerts, and monitoring.

I’m highly proficient in React with modern state management and REST/GraphQL APIs, and I care deeply about cost-efficient, observable engineering. I enjoy Agile collaboration, mentoring, and code reviews for distributed teams, consistently aiming to improve onboarding and code quality.
