I’m a backend and automation-focused software engineer who enjoys building large-scale data systems and turning complex security and operational workflows into reliable, repeatable automation. With strong hands-on experience across Python, Django, Docker, Kubernetes, and relational + NoSQL databases, I’ve delivered everything from cloud-based service architectures to data parsing, pseudonymisation, and resilient application backends in high-pressure environments. I’m also deeply interested in security operations and observability—integrating SOC automation with Swimlane, working with Microsoft Defender/Sentinel data ingest, and using Grafana/Prometheus for monitoring and visibility. Whether I’m designing API and rule-engine components, migrating and automating workflows across thousands of endpoints, or implementing TDD/CI/CD pipelines, I aim to ship maintainable solutions that perform well and scale.…I’m a backend and automation-focused software engineer who enjoys building large-scale data systems and turning complex security and operational workflows into reliable, repeatable automation.
