Software built end-to-end, with security in the architecture.

From idea to production: multi-tenant SaaS, mobile apps and internal tools, owned by one accountable engineer from the first architecture diagram to the deployed product. Security isn't a pre-launch checklist here, it's how the schema is designed on day one.

Secure multi-tenant SaaS interface with operational dashboard, roles and product modules.
01 / What we offer

What we build for you.

Production software with a single point of accountability, no handoffs, no finger-pointing.

/ 01

Multi-tenant SaaS platforms

Row-level security from the schema up, role-based access for every user type, and an architecture ready to scale past your first hundred customers.

/ 02

Mobile apps

React Native apps that share your web platform's backend, one system, every screen your users are on.

/ 03

Internal tools

Replace the spreadsheet held together by hope: dashboards, admin panels and operational tools shaped around your actual workflow.

/ 04

AI-accelerated delivery

We ship faster using agentic AI workflows, without sacrificing architecture, code quality or the security review. More product, sooner, same budget.

02 / The details

How we take you from idea to production.

The same process that took Amadoo from concept to a shipped multi-tenant platform.

1 · Architecture before code

Data model, tenancy, roles and security boundaries designed first, because retrofitting isolation into a live product is the most expensive mistake in SaaS. You review and approve the architecture before a feature is built.

Multi-tenant software architecture with roles, isolated data layers and API boundaries.

2 · Broken on purpose before launch

Before release, the same engineer who built the system attacks it: penetration testing, access control audits, abuse cases. Then a documented handover, code, infrastructure, and how to run it without us.

Pre-launch software security review with access, abuse-case and deployment checks.
03 / Proof

Already shipped.

One flagship build, end to end, and a track record around it.

Amadoo, nursery SaaS

Multi-tenant platform with 4 user roles, payments, reporting, a React Native app and an AI assistant, built end-to-end by one engineer.

20+

tables, row-level security

Full tenant isolation enforced at the database layer, designed in from the first migration.

E-learning & booking tools

Gamified e-learning systems and custom booking flows shipped when off-the-shelf couldn't fit the business.
