Database services with a written deliverable on every project.
Pick a focused engagement or a full migration. Each service has a defined output you keep — not just a Slack thread.
Database Migration
Move from MySQL, PostgreSQL, or MongoDB to a new engine, version, or cloud target with zero data loss and a verified staging dry-run.
- pgloader / AWS DMS / Mongoose-based pipelines
- Schema translation across engines
- Pre-cutover staging verification
- Rollback plan as PDF + SQL scripts
Performance Audit
Surface what is actually slow. We profile queries with EXPLAIN, MySQLTuner, and pgBadger and produce a prioritised remediation list.
- EXPLAIN-based query profiling
- Slow log analysis (pgBadger / mysqldumpslow)
- Buffer & cache configuration review
- Prioritised remediation list
Index & Query Optimization
Rewrite the queries and rebuild the indexes that move the needle, with EXPLAIN proofs and before/after timing.
- Top-N hot query rewrites
- Composite index design
- Index rebuild scripts with rollback
- Before/after benchmark report
Backup & Rollback Planning
A documented, rehearsed plan for getting back to a known-good state — not just a backup file sitting in S3.
- Logical + physical backup strategy
- PITR configuration where supported
- Restore drill in staging
- Rollback runbook (PDF + scripts)
Schema Modernization
Refactor legacy schemas with safe online migrations: column moves, type changes, and table splits without downtime.
- Online schema-change strategy (gh-ost / pt-osc)
- Backfill plans with progress tracking
- Compatibility shim for live code
- Cutover with rollback gate
Cloud DB Cutover
Move from self-hosted to RDS, Aurora, Cloud SQL, or Atlas with a verified low-downtime cutover plan.
- AWS DMS / DataStream / Atlas Live Migrate
- Replication lag monitoring
- DNS + connection-string cutover plan
- Post-cutover validation queries
Ready to migrate without holding your breath?
Pick a plan, share your schema, and we will deliver an audit, a migration, or both — verified in staging first.
