Regain total control & coherence of your critical databases
I help engineering leaders automate database testing, secure full data lifecycles, and eliminate latency bottlenecks. Elite expertise by the co-developer of MySQLTuner for uncompromising coherence.
High-impact engineering for your critical systems
Surgical management of your databases, from initial performance audits to continuous schema test automation.
Extreme Database Tuning & Engine Optimization
By the co-author of MySQLTuner: precision tuning of memory allocations (Buffer Pool, log file size), live query profiling, slow-query elimination, and lock contention eradication.
Automation & CI/CD Testing
No more stressful manual migrations. Schema deployment pipelines, automated non-regression testing, and continuous schema drift detection.
- CI/CD pipelines for database migrations
- Automated performance test runners
- Zero unmanaged schema drifts
NoSQL & Distributed Clusters
Proven track record managing massive NoSQL estates (23 Cassandra clusters, 600 MongoDB DBs for BNP Paribas). Zero-downtime clustering & partitioning.
Data Integrity, Coherence & Security Audits
Complete alignment and hardening of your critical data assets. Automated CIS Benchmarks audits, zero-data-loss replication configurations, and proven disaster recovery strategies.
Direct expertise from the co-author of MySQLTuner
As the co-developer of the global benchmark tool for MySQL & MariaDB diagnostics, Jean-Marie Renouard maintains the very rules that audit memory allocation and performance across millions of production servers worldwide.
Our Engagement Methodology
A pragmatic, measurable, zero-downtime approach designed for engineering velocity.
Diagnostic & Mapping
Deep analysis of schemas, queries, configurations, and system logs to identify performance bottlenecks with certainty.
Automation & Testing
Implementation of CI/CD schema pipelines, automated regression test suites, and drift detection scripts.
Tuning & Ongoing Coherence
Precision tuning of InnoDB variables, query indexing, knowledge transfer to your team, and continuous coherence monitoring.
