SERVICE · DB · Database Architecture & Operations

A data layer that holds under load.

Schema design, migration planning, and query tuning — plus the ongoing operations that keep a production database fast and recoverable: monitoring, backups, replication, and a restore path that has actually been tested. Built by database architects, not improvised by a generalist.

Capabilities

Scope is what we take on. Methodology is the constant discipline; it does not vary across engagements.

Scope

04 items

  • 01Schema design + data modelling (Postgres · MySQL)
  • 02Zero-downtime migrations, version-controlled
  • 03Query, index + connection-pool tuning
  • 04Backups, replication + monitored restore drills

Methodology

04 items

  • 01Workload profiled before any schema change
  • 02Migrations rehearsed in shadow before promotion
  • 03Restore tested on a schedule, never assumed
  • 04Slow-query log reviewed against an agreed budget

§02

Deliverables

What you receive at end-of-engagement. Each item ships with docs, runbook, and ownership transfer.

  1. D-01✓Schema + migration suite
  2. D-02✓Tuning + index plan
  3. D-03✓Backup + restore runbook
  4. D-04✓Monitoring dashboards

Evaluation

  • E-01p95 query latency tracked against an agreed budget on the top 20 queries.
  • E-02Restore drills run on a schedule — recovery-time and recovery-point objectives verified, not assumed.
  • E-03Migration safety: every schema change rehearsed in shadow against production-shaped data.
  • E-04Quarterly review of the slow-query log and storage growth with the engineering lead.

§04

Stack

Representative tooling. We swap individual components when the customer's environment requires it.

  • 01PostgreSQL · MySQL · SQLite
  • 02pgvector + partitioning for scale
  • 03Prisma / Drizzle for typed access
  • 04Grafana + pg_stat for observability

§05

Reference case

anonymised · NDA on request

Postgres schema redesign + zero-downtime migration for a BG fintech

p95 query latency down from 34ms to 12ms across the top-20 queries · migration shipped with no downtime over 0.4M-row tables · restore drills passing every quarter.
