## About

Full stack software engineer, 3 years at IG Group on a live trading platform\. Mostly backend: Java and Spring Boot services, REST APIs and Kafka consumers, with React on the screens that sit on top\. I take features end to end\. Requirements with the business, design, build across both layers, testing, CI/CD and release, then production support once it is live\. Recent work includes a Kafka ingestion service handling \~9\.5M messages a day, client\-facing regulatory reporting and margin APIs, and moving a trading estate off legacy JMS middleware onto Kafka\. I have also containerised services onto HashiCorp Nomad and built the GitLab CI/CD and Vault secrets setup underneath them, and I carry on\-call for what I ship\. Regulated financial services means GDPR, DORA, PCI DSS and FATCA are part of the job\. Open to relocation, including visa\-sponsored roles\.
