About me

I am a software engineer with a love for building, putting out fires before they become infernos, and reading and contributing to open source technologies.

I graduated from Swarthmore College in May 2018 with a Bachelor of Arts in Computer Science and a minor in Biology. I am a 2018 Venture for America Fellow, Howard Hughes Medical Institute Research Grant recipient, and Sigma Xi Research society member. I enjoy constantly challenging myself to improve my skills as an engineer, as well as staying up to date with the latest best practices and releases.

Attentive March 2019 - May 2020 Software Engineer, Campaign Messages I worked on the Campaign messages team - during my tenure, I worked on several high impact projects, including a migration of our Postgres event database from a monolithic store holding more than 16TB of clickstream and analytics data to separate partitions each containing a subset of event data, migrating the ETL for handling these events onto AWS Lambda and SQS, and rewriting the core messages API - responsible for powering the company's most robust product, to be more performant and durable.

Astronomer August 2018 - February 2019 Software Engineer Worked across the stack, implementing and testing platform features that enable organizations to easily adapt and productionize Apache Airflow into their own data ecosystems. My primary responsibility was to improve the monitoring around running Airflow on Kubernetes, including piping Airflow logs to Elasticsearch and providing live platform resource usage updates through Grafana. Technologies used include Docker, Kubernetes, Prometheus, Grafana, Fluentd, ElasticSearch and Kibana.
