The need

Automata AI publishes Vancelian, a savings and digital assets application. A product of this kind tolerates neither a wrong amount nor an interruption of service, and it must moreover follow a regulation of digital assets that was still taking shape during those years, while opening to new markets.

What was delivered

The application, available on Android and iOS, lets its users place euros or cryptocurrencies in interest-bearing vaults, invest in a selection of digital assets and pay with a card tied to their account; it was called Akt.io when I first worked on it, in 2022. During those years it opened to the Middle East and North Africa region and was brought into line with the MiCA regulation, in Europe, and the VARA one, in Dubai. The company reports managing more than €100 million of assets for its users today, and during my second period the application had 100,000 users, 30,000 of them active, a 4.6 out of 5 rating on the App Store and 99.98% crash-free sessions, figures that date from that period and that I have not updated since I left.

My contribution

I first worked on the application in 2022, on assignment for Fenyx Group, within a Scrum team, then came back to it from October 2023 to May 2026 as an employee of Automata AI, in a mobile team of about ten developers in which I was the technical lead for everything related to navigation.

In 2022, I took part in migrating the code to Clean Architecture and the BLoC pattern, focusing the test coverage on the business rules, then built staking, the vaults and card management, and integrated the Thales SDK that handles identity verification and two-factor authentication. From 2023, I proposed to base the application’s navigation on GoRouter, with support for deep links, which open a screen directly from a notification or an external link; the team approved the proposal and I followed its implementation through. I also took part in the opening to the Middle East and North Africa and in the compliance work, as well as in the company’s web platform for businesses, written in React and TypeScript.
