Summary
Backend engineer with eight years on high-throughput payment infrastructure. Took a ledger service from 400 to 9,000 writes per second without a consistency regression, and led the migration that moved 42 million accounts off a single Postgres primary. Comfortable owning a system end to end: schema design, rollout, the pager.
