Worked all across the infrastructure stack. Got pretty lucky with projects!
- Scaled up our internal job execution platform to hundreds of users and jobs. Wrote the core metadata and data scanning libraries used by every batch processor and verifier at the company.
- Built the core infrastructure for ensuring every file block at Dropbox is encrypted with a unique key has legally compliant crypto-shredded lifecycle management.
- Drove implementation and growth of ObjectStore, an internal blob storage system leveraging Dropbox's cost-advantaged Magic Pocket to store hundreds of petabytes of data. Subsequent HDFS and S3 deprecations gave us eight-figure annualized cost savings.

- Helped rebuild the international serving stack to route file data through ObjectStore for non-US customers.
- Drove various file data deduplication and storage footprint reduction projects that delivered another eight-figure annualized cost savings.
