Oracle and PostgreSQL engineering without layers of hand-off.

Migration from the perspective of code, database and operations.

My work includes Oracle lift-and-shift into AWS, building PostgreSQL/Aurora environments on AWS, Flyway-based database deployment and defining technical API interfaces.

In an Oracle → PostgreSQL migration I am less interested in whether a data type can be converted than in where the business logic lives, how processes are coupled through database links or Scheduler, which features are Oracle-specific, and how deployment, testing and operations work after the change.

As a specialised solo consultant, I can carry analysis, proof of concept and database migration without handing the technical context through several consulting layers. Findings from the source system remain directly connected to target decisions and implementation.

If the programme needs additional specialists or a larger delivery team, this work can integrate into an existing project. My focus remains the database, PL/SQL and migration layer.
