Six disciplines, composed into the practice your platform actually needs. Every engagement is led by a senior architect and grounded in measurable SLOs.
Quorum sets, witness placement, leader election tuning and topology drift detection across Postgres, MySQL, Mongo, Cassandra and CockroachDB.
Logical and physical streams with backpressure-aware delivery, schema evolution, and exactly-once semantics where the engine allows it.
Vector-clock aware change streams, CRDT-backed catalogs, and policy engines that make divergence rare, recoverable, and fully auditable.
Tested runbooks, warm standbys and automated promotion with safety interlocks. We rehearse failover on your schedule, not the incident's.
Zero-downtime cutovers from legacy primaries to active-active fabrics, with dual-write verification and rollback safety nets.
Named architects on call — not a rotating queue. We hold the pager for the replication layer so your application team can hold theirs.
Multi-master, observed
Replication is only as good as the observability around it. We ship every cluster with a multi-master panel that tracks commit lag, write throughput and leader state per region, all traceable to the WAL position where divergence began. No screenshot dashboards, no log-spelunking — a single pane your operators can act on.
The panel is wired into your existing SLO stack — Prometheus, Datadog, Grafana, or your own — so on-call engineers see the same numbers we do, with the same alert routes.
Engagement model
Most engagements follow the same four phases. We can compress or extend any phase, but we will never skip the audit — too many bad decisions start there.
We map your topology, replication paths, and SLOs against reality.
A concrete topology with quorum, conflict policy and DR plan.
Dual-write verification, shadow traffic, and reversible cutovers.
Named on-call architect, quarterly review, and drill cadence.
