I am a full stack developer with over 12 years of experience. I have worked on everything from large distributed systems to single person software as a service platforms. I was the founding backend engineer at Penn Interactive and built the microservices powering the Barstool Sportsbook app from the ground up. I write clean, maintainable, well tested, and full containerized services. I am always considering performance and scalability when writing software. I am also experienced on the DevOps / SRE side of the equation. I have built full CI/CD pipelines on Jenkins, Github actions, Azure DevOps, and CircleCI. I have also provisioned production infrastructure as code using Terraform.
