What I'm looking for

I’m looking to build end-to-end, HIPAA/security-compliant products in fast-paced teams—leading full-stack architecture with Python FastAPI/React, strong observability/CI/CD, and practical LLM/ML integration.

I’m a Senior Full Stack Engineer with 10+ years shipping production SaaS and greenfield products, building end-to-end systems for healthcare, fintech, and logistics. My core focus is Python FastAPI and React.js with TypeScript, with hands-on depth across C# (.NET) and Node.js backends—always with HIPAA- and security-compliant delivery in mind.

I’ve architected hybrid microservices platforms and delivered measurable outcomes across the stack: a hybrid Python FastAPI + ASP.NET Core HIPAA workflow system that increased actionable insights by 40%, and React.js + Next.js dashboards improving task completion by 25% while meeting WCAG AA accessibility. On the infrastructure side, I designed multi-region deployments on Azure AKS and AWS ECS (Terraform/Helm), achieving 99.99% uptime and cutting failover time by 67%.

I also bring strong platform instincts—API design with OpenAPI/Swagger and GraphQL, CI/CD automation with GitHub Actions/Azure DevOps/Jenkins, and observability using OpenTelemetry, Prometheus, and Grafana to reduce MTTR and improve reliability. In applied AI work, I’ve integrated LLMs and ML pipelines (OpenAI + ONNX/ML.NET), reaching 88% automated triage accuracy and reducing manual review by 56%—all while maintaining quality through testing and secure access controls.
