What I'm looking for

I’m looking to own end-to-end delivery on secure, mission-critical products—building full-stack features, optimizing data and APIs, and improving reliability with cloud-native CI/CD, observability, and automation.

I’m a Senior Full Stack Software Engineer with 8 years of experience building and scaling enterprise applications across defense, energy, and cloud services, with an emphasis on owning delivery end to end—from system design through production support. I work comfortably across the stack, partnering with product teams, architects, and junior engineers, and leading code reviews and technical discussions in Agile settings.

I consistently deliver production-ready features using React, TypeScript, and Next.js on the front end, and C# (.NET Core / ASP.NET Core), Java (Spring Boot), Node.js, and Python (FastAPI) on the backend. I’ve built distributed microservices, improved performance through query optimization and indexing on PostgreSQL/SQL Server, implemented caching with Redis, and streamlined release cycles using GitHub Actions CI/CD with containerized deployments on Docker and Kubernetes. I keep mission-critical platforms observable and reliable with Datadog and CloudWatch (including 99.9 uptime work), and I build security-ready APIs using OAuth 2.0, JWT, and role-based access control—while applying WCAG 2.1 accessibility standards to key UI components.
