Juan José Granados
Technical Leader · Super App Platform @ BCP
I lead platform teams that make Super App experiences reliable across hybrid and native stacks—architecture, delivery practices, and engineering enablement.
Technical leader with about a decade in software—deep iOS/Swift background, now leading a platform team for a Super App that combines React Native with native iOS and Android.

about.md
A path from shipping apps to enabling teams
I started in web and campus systems work, then moved fully into iOS—shipping consumer and marketplace apps before specializing in financial mobile products.
Over time my role shifted from implementing features to shaping architecture, mentoring teams, and improving how modules are designed, tested, and released.
Today I lead a Platform team for a Super App, working across React Native, iOS, and Android—the same concerns that mattered as an iOS SME, now at platform scale: architecture, cohesion, and a trustworthy delivery path.
