Overview

Senior .NET/C# Developer — Project: Oracle to PostgreSQL Migration • Day Rate: £500 - £530 Inside IR35 • Hybrid working: 1 day per week onsite • Nottingham

About the Project

Our client are embarking on a strategic transformation of a legacy system built on PHP and Oracle, migrating to a modern architecture using PostgreSQL and .NET (C#). This is a complex re-engineering initiative involving the conversion of over 240 Oracle stored procedures—many of which are highly intricate—into performant, maintainable C# code. The new system will operate alongside the legacy platform during the transition, requiring robust integration and support for business-as-usual (BAU) operations.

They are also leveraging AI-assisted tools to accelerate and enhance the migration process, offering a unique opportunity to work at the intersection of legacy systems, modern development, and AI-driven engineering.

Key Responsibilities

• Re-engineer Oracle PL/SQL stored procedures into C# services.
• Design and develop .NET-based components that integrate with legacy PHP systems and new PostgreSQL databases.
• Collaborate with business analysts and stakeholders to ensure functional parity and identify opportunities for improvement.
• Contribute to the design and implementation of a hybrid architecture supporting phased migration.
• Utilize AI-assisted tools to analyze, translate, and optimize legacy code.
• Support BAU operations during the migration to ensure system stability and continuity.
• Participate in code reviews, testing strategies, and technical documentation.
