About
From ERP support to full-stack development
I'm a software developer based in Dublin, Ireland, with around five years of experience progressing from ERP Support Analyst to full-stack Software Developer. That path gave me a grounding in real business operations before I ever wrote a line of application code — I understand the processes software is meant to support, not just the syntax.
Today I work across the stack: Laravel and Java on the backend, React, Vue.js, and React Native on the frontend, and Oracle, MySQL, and Redis underneath. I'm especially interested in queue-driven architectures, background job scheduling, and the observability tooling — Grafana, Prometheus, Loki — that keeps business-critical systems reliable.
I hold a Stamp 2 visa and am eligible to work in Ireland, currently looking for full-stack or backend-leaning roles with teams solving real operational problems.
