Online Storage team!

• Architected a permissioned, auditable system for product engineers to securely access their live TiDB databases with Go and S3

• Sped up team-wide Aurora MySQL to TiDB migration using TypeScript to automate tedious, error prone tasks like tearing down replication, creating rollback clusters cloned from Terraform/YAML configs, and verifying offline dump parity in Redshift

• Led resharding of primary MongoDB cluster (at the time 150+ TB) to better isolate workloads and improve reliability

• Discovered and implemented a workaround for a SS table compaction bug affecting unbounded range queries to ensure a timely migration. Worked to align with the vendor on the issue and get a fix long term.

• Mentored a summer intern through the successful production deployment of a TiDB database cluster-to-cluster migration tool

• Developed a system for monitoring and querying Stripe’s 1200+ MongoDB replica sets by health, config, sharding, etc.

• Iterated on design and feature set to best serve the needs of other Document Database engineers, especially those on-call

• Built a gRPC service in Go to discover replica sets from Consul and periodically index their metadata using Blevesearch

• Integrated the replica set search and lookup functionality into the team’s internal web tooling using React and Flow

• Shuffle was a podcast sharing and discovery platform centered around short digestible podcast highlights

• Spearheaded web-based internal tool for curating user feeds, managing the beta waitlist, monitoring the podcast audio transcription pipeline, and configuring automatic transcription for popular shows using React and TypeScript

• Facilitated product-wide database migration from Firestore (NoSQL) to PostgreSQL with an idempotent data importing system and dual write/read tooling for a smooth transition

• Collaborated with frontend engineers to deliver features such as social loop notifications, following, comment liking
