Schema design, sharding and caching for systems that outgrew their first database. We fix the data layer before it becomes the reason everything else is slow.
Trusted by teams worldwide
Six service lines covering design, growth, availability and the queries that are quietly costing you.
Data architectures we have taken to production, with the trade-offs each one carries, backed by our performance and infrastructure teams.
Schema-per-tenant or row-level isolation patterns give you data segregation without sacrificing query performance.
ACID-compliant schemas, double-entry ledger design, distributed transactions, and audit trail tables.
ClickHouse or TimescaleDB for time-series data, OLAP query optimization, and streaming ingestion pipelines.
Offline-first sync architectures, conflict resolution, partial indexes, and hot-path caching for mobile-scale workloads.
HIPAA-ready designs with field-level encryption, access logging, and FHIR-compatible schema structures.
Product variant models, inventory tracking, flash-sale concurrency controls, and search-optimised Elasticsearch sync.
One look at your schema, your slow query log and your growth curve usually finds the real bottleneck. It is rarely the one the team is arguing about.

We profile the schema, indexes, query patterns and growth curve, then agree a fixed quote.
Target architecture, migration path and rollback plan designed before changes.
Schema, indexing and caching changes shipped incrementally with benchmarks.
Load testing at projected volume plus a dry-run migration on a copy.
Cutover with monitoring, then tuning as real traffic arrives.
Typical range once N+1 patterns and missing indexes are fixed.
Online migration patterns so cutover is not an outage.
Sharded and replicated estates we have taken live.
Typical time from audit to a difference users can feel.
Real products, real users, real numbers, across health, mobility, delivery and education.
