Available to hire
I’m Leonardo Maria Miliacca, a Senior Full-stack Developer and Technical Lead with 10+ years of experience delivering scalable web and mobile applications. I specialize in Angular and Ionic at senior levels, with strong skills in React and backend development using NestJS, Symfony and Strapi.
I’m passionate about designing multi-tenant SaaS platforms and headless CMS architectures, building enterprise-grade frontends, and driving quality through automated testing and CI/CD. I enjoy rapid prototyping, API design, and data automation, and I love collaborating with designers and stakeholders to balance performance, usability and business goals, while staying curious about blockchain and emerging technologies.
