I worked on the Data Storage team at Brex, managing the company's hundreds of Postgres databases running on AWS RDS. I spearheaded a multi-quarter project to binpack our massive database fleet, ultimately yielding a 40% reduction in cloud costs.

I also built fully automated zero-downtime Postgres infrastructure migrations using Temporal, Go and Terraform, which enabled the team to perform hundreds of toil-free major version upgrades on our largest scale databases.

I worked on the Database Reliability team for Postgres, where I led the development of Postgres on Kubernetes as a database platform. I took this from ideation to production, where it eventually served a number of high throughput production clusters with lower latency and higher availability than our previous cloud provider-managed databases. This was received by company leadership as the future of Postgres at Datadog.

I also worked on tooling and infrastructure to manage massive scale Postgres clusters deployed across multiple regions in AWS, GCP and Azure.

I planned and executed a series of projects to improve the reliability and cost efficiency of CMB's database systems. This included major infrastructure migrations and upgrades of Postgres (9.6 to 13), Elasticsearch (2 to 7) and Redis (4 to 6).

Later I was promoted to the technical lead of the backend platform team. I was heavily involved in hiring and project planning, and I mentored several teammates.

I worked on Baja, the distributed database/pubsub layer of Cosmos (not CosmosDB), Microsoft's internal big data platform. I also helped drive adoption of Spark, Kafka and other open source systems across the Bing org.
