We help growing companies keep their PostgreSQL and MySQL databases fast, reliable, and secure — so their engineering teams can focus on building product.
We've spent years in the trenches with production databases — diagnosing slow queries at 2am, rebuilding replication after catastrophic failures, migrating millions of rows without downtime, and designing database architectures for systems that needed to scale by 100x. We've seen what happens when companies don't have access to deep database expertise: slow products, escalating cloud bills, preventable outages, and engineering teams spending days firefighting problems that a senior DBA could solve in hours.
The problem is that dedicated DBA talent is expensive. Hiring a senior DBA in the US or Europe is a major annual investment once you factor in salary, benefits, equipment, and management overhead. Most growing companies can't justify that headcount, but they absolutely need that level of expertise.
ReliaDB exists to close that gap. We serve companies internationally from Barcelona, Spain. We provide senior-level PostgreSQL and MySQL expertise to teams in Europe and North America with deep specialization and consistently high delivery quality.
The expert team you meet is the same team that works on your database. There's no account-manager bottleneck, no junior hand-off, and no project confusion.
Our core expertise is PostgreSQL and MySQL — the two databases that power the vast majority of production SaaS and e-commerce systems. We also work extensively with cloud-managed database services (AWS RDS, Aurora, Google Cloud SQL) and have deep experience with the ecosystem around these databases.
Query optimisation, EXPLAIN analysis, index strategy, partitioning, streaming replication, logical replication, Patroni HA, vacuuming and bloat management, extensions (pg_stat_statements, PostGIS, TimescaleDB).
InnoDB optimisation, query tuning, binlog-based replication, Group Replication, ProxySQL, connection pooling, slow query analysis, schema migration strategy.
RDS, Aurora, RDS Proxy, Parameter Groups, Enhanced Monitoring, Performance Insights, cost optimisation (gp3 storage, right-sizing, reserved instances), multi-AZ architecture.
Patroni, repmgr, pg_auto_failover, ProxySQL, HAProxy, multi-AZ RDS, failover testing and runbooks, backup strategies (pgBackRest, WAL-G, mysqldump, Percona XtraBackup).
Slow query log analysis (pgBadger, pt-query-digest), EXPLAIN / EXPLAIN ANALYZE, index design, query rewriting, connection pooling (PgBouncer, ProxySQL), configuration tuning.
Oracle to PostgreSQL, MySQL to PostgreSQL, version upgrades, on-premise to AWS RDS/Aurora, zero-downtime migration strategies, logical replication-based cutovers, Flyway and Liquibase.
Operating from Barcelona, Spain (CET/CEST) gives us strong real-time collaboration with European teams while maintaining smooth overlap with North American time zones.
We provide 24/7 support coverage for production-critical systems. Client communication happens via Slack, email, or video call — whatever your team prefers.
We run ReliaDB as a specialist consulting practice. When you reach out, you talk directly with the team that will work on your database. There's no hand-off to junior consultants and no project-manager bottleneck. This makes communication faster, more accurate, and better for your database.
If your database doesn't actually have a serious problem, we'll tell you. We'd rather earn long-term trust and be the team you call for real emergencies than oversell a small issue. Our business runs on long-term client relationships, not one-time engagements.
Good database consulting doesn't leave your engineering team in the dark. We explain what we're doing, why we're doing it, and how your team can maintain and build on the work after the engagement. We write documentation and leave your team more capable than when we started.
We reply quickly during business hours, and same-day for non-urgent questions. If you're on the monthly support retainer, you get priority response for production issues at any time. We take availability seriously because database problems don't care about time zones.
We charge fair rates for clearly defined outcomes, not inflated hourly rates designed to maximize billing. On audit and project engagements, you know exactly what you're getting and what you're paying before we start. Retainer clients get defined hours and deliverables, not vague promises of "availability".
Start with a free 30-minute call. No commitment, no sales pitch — just an honest conversation about your database setup and what's worth fixing.
