About the apps

From an idea to an app.

Recurden helps people make subscription renewal decisions. Aftermark is about finding notes the way you remember them. Leaf keeps Markdown references alongside your work.

Recurden is pending App Store release. Aftermark and Leaf are in development.

  • Recurden

    A private subscription renewal assistant. See upcoming charges, trial endings, and price changes, then decide what to keep, defer, or cancel.

    Pending App Store release · iOS / SwiftUI

  • Leaf

    A read-only Markdown layer for macOS. Open a reference, keep it beside your work, and dismiss it without changing the source file.

About me

From database research
to quantum computers.

I’m a software engineer in Paris. I received my PhD in Computer Science from Université Grenoble Alpes in 2021, then worked at Opensee before joining C12 in May 2025.

My interests include databases, distributed systems, queuing systems, and quantum computing. Outside work, I'm building anything, mostly native apps for iOS and Mac recently.
