Senior .NET/C# Developer

Head Resourcing Ltd • TRAFFIC • Nottinghamshire, Nottingham, United Kingdom • 5d ago

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.
