Senior🎓
Top SchoolAlejandro Calera is a serial tech founder and CTO with nine years of professional experience and over a decade programming since childhood, now leading AI-driven product strategy and engineering at The AI Business. He has a proven track record of turning ideas into production platforms quickly—building Nuela’s end-to-end product in 18 months (a project that might normally take 4+ years) and scaling teams and value rapidly through Series A. Comfortable across the full stack, Alejandro has shipped mobile, frontend and backend systems using Node.js, TypeScript, React/React Native, Kotlin/Swift and multiple databases, and has led initiatives from microservices to telecom VoIP and WireGuard work. He combines hands-on engineering with people leadership, having grown teams, instituted strong dev practices, and mentored engineers across startups like Packar, Fisify and Influencity. Based in Majadahonda, Spain, he also contributes open-source projects and maintains a public GitHub and portfolio that reflect a preference for rapid iteration and production-ready tooling. Unusually for his age, he has real operational experience in diverse contexts—from military signals programming to hitting 60k MRR as a CEO—bringing resilience and product focus to technical leadership.
