Senior🎓
Top SchoolMario Sánchez is a software engineering consultant based in Barcelona with 10 years of hands-on experience building high-performance web applications across the full stack, primarily with JavaScript (client and server) and PHP. He has driven migrations from legacy stacks to modern React-based frontends and led the development of high-traffic, well-tested PHP APIs using hexagonal architecture and continuous delivery. Mario has practical tech-lead experience shaping team practices—pair/mob programming, TDD, and CI/CD—to increase resilience and developer velocity, and he’s comfortable toggling between individual contributor and leadership roles. A homebrewing enthusiast, he brings the same craft-minded attention to quality and iteration to software as he does to brewing, often focusing on performance and developer experience improvements that aren’t always visible in product metrics.
