About My Development Work
My experience spans data infrastructure, data science, and backend engineering.
I work with public cloud platforms, but I also enjoy designing and running pipelines on my own local servers. Recently, I deployed a Kubernetes cluster with services I use in my build and data workflows, including Apache Airflow, GitLab CI/CD, a private Docker registry, and Apache Superset. Building these systems end to end helps me understand how each service behaves in production-like environments.
I am passionate about software development and like sharing what I learn with the open source community.
