I'm a software engineer with 10+ years of experience in data engineering and backend systems. I work primarily with Java, Scala, Python, Spark, Databricks, Kubernetes, Airflow, and cloud infrastructure, with a focus on building scalable, performant, and secure data platforms and backend systems.
I also enjoy contributing to open-source projects and sharing what I've learned through technical talks.
An overview of my open-source contributions. Below are some selected pull requests, categorized by typical software engineering activities.
- Added new APIs to Eclipse Collections, formerly known as Goldman Sachs Collections.
- Added a command-line option to sbt-jmh for exporting JFR reports.
