Oracle Developer - Pl/SQL - Migration - 6 month contract (Umbrella engagement only) I have an immediate opportunity for an experienced Oracle Developer to play a key role in a large-scale modernisation programme. Our client is overhauling a long-standing enterprise system originally built with Oracle and PHP, moving towards a modern, service-driven architecture built in .NET (C#). This isn't just a database swap-it's a full re-engineering of business-critical systems and logic. The current platform includes a large, complex Oracle environment with over 240 stored procedures and extensive embedded logic. The new solution will run on .NET with a PostgreSQL or MySQL backend, and you'll help drive the transition. As such I am keen to speak with candidates who have: • A background working with Oracle PL/SQL, including advanced use of procedures, triggers, and packages, ideally for corporate organisations • Previous experience of re-engineering database logic into .NET/C# systems-not just rewriting, but redesigning • Deep knowledge of Oracle architecture and how backend logic interfaces with applications • Hands-on experience with data migration from Oracle to PostgreSQL or MySQL • Ability to work across engineering, QA, and business teams • Clear, professional communication and documentation abilities Desirable skills include: • Experience with legacy PHP systems tied into Oracle • Familiarity with AI-driven development and code migration tools • Knowledge of database version control, CI/CD practices, and service-based architecture • Experience with large-scale system transformations or brownfield projects • C# and .NET expertise, particularly in back-end or service-oriented development Interested?
