Dailyn app
Dailyn is a french startup that started with the vision of becoming a super-app that aimed to connect individuals in their hyperlocal environment. It included a marketplace of goods and services from small local businesses, a chat with commercial features, as well as a tool for the management of local public or private events, among the many features envisioned for the super-app.
Most recently, Dailyn simplified its value proposition to become a payment and cashback solution for small businesses, therefore concentrating the activity of the app on the marketplace, the chat for conversationnal commerce and the digital wallet with cashback.

My role at Dailyn
Senior Product Designer
I was hired as the first UX designer of the team in the summer of 2021 and worked on almost all user interface and user experience of the mobile app for iOS and Android.
Since then, the product design team has grown to up to 5 product designers in the peak of the team's growth. While the team's organisation had a flat structure, I was the point of reference for guiding new and junior designers to maintain a high level of homogeneity, quality and skills across the company's different verticals.
As a product designer at Dailyn, I've worked closely with all levels of the organisation from the CEO, CTO, CPO, to the sales and art direction teams. Above all, I've worked closely with product owners, front-end and back-end developers within cross-functional teams where I had full ownership of my project's from strategy to research, ideation, design and implementation.

Dailyn overview
This prototype showcase a full customer journey within the Dailyn App as it was in the beginning of 2023.
The prototype shows some parts of the mobile application on the user side, including the discovery of shops and restaurants, the detailed page of a business, possible interactions between a user and a professional, the payment flow, and the chat.

A systemic approach to design
Design system
The creation of a robust and ever evolving design system has been at the core of our design strategy at Dailyn as soon as we started increasing the team size and scope of the super-app. We initially documented our design system with Zeroheight; later on, we decided to add all documentation directly on each Figma component files to avoid the maintenance of 2 directories and potentially 2 sources of truths.
Once the basic components of the Design system were accepted by both the design and development team, every new project had to follow a systematic approach to design by creating new shared components for any new feature that needed one, with cross validation from the other team's designers.

Dailyn Chat
Once the marketplace was fully designed, I have been responsible for creating from scratch a fully custom chat system.
While a chat may seem to follow a lot of known patterns, its complexity lies in custom patterns and interaction details.
The first animation below shows the interaction design of a message reaction.
The second animation shows a PubSub pattern (publisher / subscriber), which allows a professional (the publisher) to send news to all its subscribers through a chat channel. The subscriber can only view the news in that channel, but can easily switch to private 1-to-1 conversation with the professional through a simple tab system.
