Our Process
From Slow Queries to Predictable Performance
A process that measures before it changes anything, because database work is easy to get confidently wrong.
1
Week 1
Discovery
We profile the schema, indexes, query patterns and growth curve, then agree a fixed quote.
2
Week 1–2
Design
Target architecture, migration path and rollback plan designed before changes.
3
Week 2–8
Development
Schema, indexing and caching changes shipped incrementally with benchmarks.
4
Week 6–10
QA & Hardening
Load testing at projected volume plus a dry-run migration on a copy.
5
Ongoing
Launch & Support
Cutover with monitoring, then tuning as real traffic arrives.
Measurable Impact
Numbers From Database Work
10–100x
Query speedups

Questions We Hear Every Week
We work across PostgreSQL, MySQL/MariaDB, MongoDB, Redis, Elasticsearch, ClickHouse, CockroachDB, TimescaleDB, Apache Cassandra, DynamoDB, and managed cloud services like AWS Aurora, Google Cloud SQL, and Azure Cosmos DB. We select the right engine for your specific workload, not the most familiar one.
Yes. We use expand-contract patterns, online DDL (pg_repack, pt-online-schema-change), and dual-write strategies to migrate schemas and data with zero downtime. We also handle cross-engine migrations (e.g. MySQL → PostgreSQL) using tools like pgloader or custom ETL pipelines with cutover windows under 60 seconds.
Absolutely. We start with a comprehensive audit: EXPLAIN ANALYZE on slow queries, pg_stat_statements analysis, index bloat reports, N+1 detection, and lock contention profiling. We then deliver a prioritised optimisation plan with estimated impact for each change. Many clients see 90%+ query time reductions within the first sprint.
It depends on your data shape and query patterns. Relational data with complex joins and strict consistency → PostgreSQL. Flexible document structures with high write throughput → MongoDB. Ultra-fast caching or session storage → Redis. Analytical time-series → ClickHouse or TimescaleDB. We'll recommend the right fit after a short discovery call.
We implement row-level security (RLS) in PostgreSQL, field-level encryption for PII, role-based access control (RBAC), audit logging, and network isolation (VPC, private subnets). For regulated industries (healthcare, fintech) we align schemas with HIPAA, PCI-DSS, and GDPR requirements from the outset.
A green-field schema design engagement typically takes 2–4 weeks from discovery to production-ready setup. Complex migrations or architecture redesigns for large existing systems range from 4–12 weeks. We provide a detailed project plan with milestones during the proposal phase.
