Curriculum Vitae

Profile

Software engineer based in Cork, Ireland, working across TypeScript/Node.js and Java/Spring Boot. I build backend systems and AI-powered products — from a multi-tenant, real-time meeting-intelligence platform to full-stack projects shipped end to end — and I care about clean, well-tested, maintainable code. Stamp 4 holder with full working rights in Ireland (no visa sponsorship required).
