Database Engineering

We tune, replicate, secure, and recover the database tier across PostgreSQL, MySQL/MariaDB, MongoDB, Redis, Elasticsearch, and ClickHouse. From a single 50k-QPS Postgres instance to a 12-node Galera cluster with cross-region failover — we own the schema review, the index strategy, the replication topology, the backup verification, and the recovery rehearsals.

We also handle the unsexy work: vacuum scheduling, bloat monitoring, slow-query reviews, deadlock root-cause analysis, query-plan audits, and connection-pool sizing. Every database we manage has a documented recovery time objective (RTO) and recovery point objective (RPO) that we test quarterly — not just promise.

Whether you are migrating off a managed service to cut cost, scaling out from single-node to cluster, or recovering from "the previous DBA left and nobody knows the password" — we have done it. Repeatedly.
