Introduction
I am a Full-Stack Software Engineer with over 3 years of experience building scalable web applications and managing cloud infrastructure. My technical ecosystem centers around Java (Spring Boot, Maven), SQL, JavaScript, TypeScript and Node.js for backend architecture, paired with modern frontend frameworks like React (Vite, PrimeReact). Currently, at Grupo Pulsati, I drive end-to-end feature delivery and own the infrastructure side of our products. My hands-on experience includes designing and optimizing PostgreSQL databases, creating interfaces with React (Vite, RSuite), containerizing applications with Docker, and orchestrating deployments using AWS services (including Amplify) within Linux environments. Fluent in French (Native) and English, I combine deep technical expertise with strong cross-border communication skills, thriving in agile and multicultural environments. Currently based in Ireland and open to relocation, hybrid, or remote opportunities across Ireland and Europe.
