Systems I built, what constrained them, and what changed as a result.
An eight-endpoint async service that took per-file processing from over fifteen minutes to under thirty seconds for about a thousand users.
A reconciliation service that drove isolated SAS Studio pods from database state, cutting secure provisioning from days to minutes.
An Airflow-orchestrated approval pipeline with database-backed tracking that cut team effort 80% and about $200K a month in leakage.
Trust and safety mechanics for an agent platform: canonical-hash verification, YAML write-safety, and a CI check that blocks stub implementations.
