- 🔭 Part of the team that builds and maintains OpenEPCIS — open-source tooling for the GS1 EPCIS 2.0 supply-chain traceability standard (capture, store & query).
- ⚙️ I design cloud-native microservices and REST APIs end-to-end — from reactive backends to production front-ends, DevOps infrastructure, and open-source tooling.
- ⚡ I specialise in reactive, non-blocking services with Quarkus and SmallRye Mutiny, with a strong focus on streaming, memory efficiency, and GraalVM native builds.
- 🌐 I work across the full stack — Nuxt / Vue front-ends (Nuxt Content, Nuxt UI, Nuxt SEO) and content-driven sites like openepcis.io and benelog.com.
- ☁️ I deploy and operate services on AWS & Kubernetes (EKS), with Terraform IaC, CI/CD in GitLab/GitHub, and observability via OpenTelemetry & Jaeger.
- 🔐 I secure APIs with Keycloak, OAuth 2.0 / OIDC, and JWT.
- 🧩 I care about XML ↔ JSON/JSON-LD equality, clean code, and standards-correct implementations.
- 🏆 Active member of the GS1 GSMP working group — credited by name in the official GS1 EPCIS 2.0 standard document.
