A quick introduction, grounded in Bruno's verified résumé.
Dublin, Ireland Quero Delivery
Relocated to Dublin, Ireland — August 2026 🇮🇪 Portuguese (native) · English (full professional proficiency)I'm a Senior Software Engineer with 8+ years of experience building and scaling Node.js/TypeScript systems in production, with a strong focus on microservices, event-driven architecture and Domain-Driven Design.
I currently lead the engineering function at Quero Delivery, a growing food-delivery platform, where I own architectural decisions, cloud infrastructure on AWS (EKS, S3, CloudFront), and CI/CD end to end.
I'm comfortable across the stack — React, Node.js, MongoDB, PostgreSQL — and used to working in distributed, English-speaking teams.
