I'm keen to speak with candidates who bring experience across several of the following areas:

Solution Architecture: Designing enterprise-scale solutions and modernising complex technology platforms.

Java & Microservices: Strong engineering foundations, ideally including Java, Spring Boot, REST APIs and distributed systems.

Event-Driven Architecture: Experience with Kafka, IBM MQ, Solace or similar messaging technologies.

Data & Cloud: Oracle, PL/SQL, data integration, AWS and Snowflake.
