Contributor space

Parishes and retreat centres keep their own listings up to date.

Reliable information comes from the people who know it. Parish priests, secretaries, catechists and guest managers run their own listing from the app, with no password to remember.

My background

Ivorian and based in Montreal since 2025, I hold a Higher Technician Certificate (BTS) in computing, specialising in application development, from Groupe EDHEG in Bouaké, and a degree in software engineering from the Institut Ivoirien de Technologie in Grand-Bassam. I am now studying for an MBA in information technology management at Université Laval. Since 2019 I have been designing websites and digital tools, and I have supported the digital communication of organisations such as the UNAIDS country office in Côte d’Ivoire. In 2021 I founded the Centre Marée de Lumière, an association that has already trained more than 1,500 young women and teenagers in digital skills.

Why Lucerna?

Finding a Mass time in an unfamiliar city, or a retreat centre to rest for a few days, still too often depends on word of mouth. As a Catholic Christian, I wanted to put digital tools at the service of the Church in Africa: simple, reliable information, kept up to date by the parishes themselves, available to everyone, even on a basic phone with a weak signal. Lucerna, Latin for lamp, aims to be a small light on everyone’s way.

A volunteer initiative run by Marée de Lumière.

Lucerna is free and runs on your donations.
