A clear vision, a hard foundation.
Amadoo's founder had a clear product vision: a modern platform that could manage nurseries end-to-end, multiple tenants, four distinct user types (admins, managers, practitioners, parents), payments, reporting, and AI-assisted functionality, all from launch.
The challenge wasn't the vision. It was building it as a secure, scalable, multi-tenant SaaS without spending two years on the foundation.
End-to-end build, one accountable engineer.
Umbra Penance led the full technical build of Amadoo's platform, owning architecture through to shipped features:
- / 01Multi-tenant SaaS infrastructure: Postgres schema with row-level security across 20+ tables, ensuring full data isolation between nurseries.
- / 02Role-based permissions system covering admin, manager, practitioner, and parent users across 12 distinct staff positions.
- / 03Authentication and secure data access built on least-privilege principles, with security architected in rather than retrofitted.
- / 04Core operational features: attendance, certifications, curriculum planning, billing, messaging, and a real-time activity feed.
- / 05Cross-platform mobile app in React Native, translating the full web experience into a native iOS and Android product for parents and practitioners on the go.
- / 06AI-powered functionality, including Ami, Amadoo's nursery assistant, delivering AI-generated reports and operational support.
Throughout, the brief was end-to-end ownership: architecture, security, delivery, under a single accountable engineer.
A foundation built to scale.
Amadoo progressed from concept to a fully functioning platform capable of supporting nurseries through a single system.
The technical foundation is built to scale: multi-tenant from the schema up, secured at the data layer, and ready for the next phase of growth.
“I chose Adel because of his technical expertise, ownership mentality, and ability to solve complex problems without overcomplicating them. From the beginning, he understood both the product vision and the technical requirements needed to make it a reality.
Adel architected and built the core foundations of Amadoo, including our multi-tenant SaaS infrastructure, role-based permissions, secure data access controls, authentication systems, reporting functionality, and AI-powered features through Ami, our nursery assistant. He consistently delivered high-quality work, solved difficult technical challenges, and helped transform concepts into production-ready features.
I would absolutely recommend Adel to any founder or business looking for a reliable technical partner. He combines strong engineering ability with genuine ownership and a commitment to delivering results.”
