• Integrate with relational and/or NoSQL data stores (Oracle/PostgreSQL; DB2 a plus given the estate).


• Contribute to solution design, code reviews, and non‑functional concerns - performance, resilience, security, observability.


• Collaborate with architects, BAs, testers and product owners; support SIT/UAT and production releases.
