Senior software engineer specializing in scalable cloud-native full-stack and microservices solutions.
What I'm looking for
I am a senior software engineer with over 12 years of experience building full-stack, cloud-native systems focused on reliability, security, and performance. I specialize in Python backends (Django, FastAPI), real-time processing, and scalable microservices.
At Walmart I designed HIPAA-compliant backend services, migrated monoliths to AWS ECS microservices, and implemented serverless workflows with Lambda and Step Functions, cutting API latency and improving fault isolation. I built real-time data pipelines using Redis and RabbitMQ and automated infrastructure and CI/CD using Terraform and GitHub Actions.
Previously at Bring A Trailer I developed a high-concurrency auction backend with FastAPI and PostgreSQL, implemented WebSocket-driven real-time updates, and maintained rigorous test coverage across frontend and backend. I also contributed to frontend systems using React, Storybook, and Material UI to standardize UI patterns and speed handoffs.
I value pragmatic engineering, strong cross-functional collaboration, and documentation—having created a documentation site with Next.js and Markdoc—and I focus on delivering secure, observable, and maintainable systems that scale with user needs.
