Senior .NET/C# Developer (Oracle to PostgreSQL migration) - Finance - Remote
Duration: 6 months
Rate: £500 - £600
Start: ASAP
My client is looking for a Senior Developer to join the team to help with a migration. They are undertaking a strategic transformation of a legacy system built on PHP and Oracle, migrating to a modern architecture using PostgreSQL and .NET (C#). This is not a simple lift-and-shift; the project involves re-engineering over 240 Oracle stored procedures, some highly complex, into performant, maintainable C# code. The new system will coexist with the legacy platform during the transition, requiring careful integration and support for business-as-usual (BAU) operations.
Key Responsibilities
1. Collaborate with the existing team to re-engineer Oracle PL/SQL stored procedures into C# services.
2. Design and implement .NET-based components that integrate with both legacy PHP systems and new PostgreSQL databases.
3. Work closely with business analysts and stakeholders to ensure functional parity and identify opportunities for enhancement.
4. Participate in the design of a hybrid architecture that supports phased migration.
5. Use AI-assisted tools to analyse, translate, and optimize legacy code.
6. Support BAU operations during the migration period, ensuring system stability and continuity.
7. Contribute to code reviews, testing strategies, and documentation...
