Eliminate database single points of failure, prevent costly application outages during hardware failures or maintenance windows, and ensure verifiable zero data loss.

We architect, deploy, and benchmark high-availability database clusters powered by PostgreSQL (with Patroni, pgBouncer, and WAL-G) or MariaDB Galera synchronous multi-master clusters on hardened CentOS Stream 10. Every deployment includes sub-second automated failover, connection pooling, continuous streaming backups, and verified point-in-time recovery (PITR).

Zero-Downtime Maintenance: Perform OS upgrades, security patches, and hardware replacements on individual nodes without application downtime.

Sub-Second Automated Failover: Distributed consensus agents detect node or network failures and promote healthy replicas instantaneously without manual intervention.

Connection Pooling & Query Routing: Decouple application connection spikes from backend database worker limits using high-performance connection pooling.

Verifiable Disaster Recovery: Continuous transaction log streaming to S3-compatible object storage with automated point-in-time recovery drills.

Multi-Node HA Synchronous Database Cluster: Production 3-node PostgreSQL/Patroni or MariaDB Galera cluster on CentOS Stream 10 with Raft/etcd consensus and automated split-brain prevention.

Transaction-Level Connection Pooling Layer: Dedicated pgBouncer or HAProxy deployment with intelligent read/write splitting and sub-second backend health isolation.

Continuous Streaming WAL & S3 Backup Pipeline: Encrypted transaction log streaming (WAL-G/pgBackRest) with automated daily base snapshots and retention policies.

Verified Point-in-Time Recovery (PITR) Drill: End-to-end recovery verification report demonstrating restoration to an exact minute and transaction ID.

Cluster Operations Runbook & Benchmark Report: Stress-testing results (pgbench/sysbench), node replacement procedures, and administrative maintenance guides.
