06 / DATA & SYSTEM INTEGRATION

Connect your systems. Trust your data.

Data trapped in separate systems slows everyone down, and database migrations are risky without a plan. I design integrations and migrations that move data reliably and can be verified at every step.

Part-time remote consulting · Around 10–20 hours/week. Scope and meeting overlap agreed before work begins.

IS THIS A FIT?

When this helps most

  • Teams re-key the same information into several systems.
  • You want to reduce proprietary database licensing costs by moving to PostgreSQL.
  • Reports disagree because data flows between systems are fragile or undocumented.

HOW I CAN HELP

What working together looks like

01

Integration design

Map how data should move between systems and choose the right approach: APIs, messaging, or scheduled ETL.

02

Database migration

Plan and carry out Oracle or SQL Server to PostgreSQL migrations, including schema conversion and application changes.

03

Validation plans

Define how you will prove the migrated data is complete and correct before you switch over.

04

Event-driven integration

Use messaging such as Kafka when systems need to react to changes in near real time.
