I am a software engineer with more than 13 years of experience. I had multiple roles throughout the years: developper, architect, documentation writer and support engineer. I have a complete overview of what it means to build products and I can provide insights that will help you grow your business further with tech.
My current technical stack is around React / Gatsby.js / AWS. I also have a strong expertise building search UIs with Algolia: I built the core of the UI libaries and did technical support during the whole experience.

Algolia is a SaaS company delivering the best user-facing search experience. It is behind the search of thousands of websites, in a wide variety of industries from e-commerce to media. My mission there was to bring JS developer tools to life. I have created and maintained JS libraries that helped thousands of developers build search UI in minutes rather than days. I have also contributed my dataviz experience to the dashboard, and I have tried myself at product management when there was none.

Playlist detective
Since July 2017
Playlist Detective is an attempt to ease music discovery with playlists. Back in the days, people were sharing mixtapes: some songs we knew and others we did not, therefore expanding our musical horizons. Playlists are the same, and playlist detective lets you search for songs or artists you like in order to stumble on your new favorite songs. During the release of the "search for facet values" feature at Algolia, I realized that searching for playlists could be a good use case for a Spotify playlist search engine. It started as a prototype with InstantSearch.js and no other libraries. Since then, it has been rewritten using Gatsby, React and React-InstantSearch

The mission here is to make sure that the feature is ready:
- it is configurable in the dashboard
- it has a UI pattern (validated by user testing)
- this pattern is available in the UI toolkits
- the blog post is ready with a demo

For 2 years and 11 months – started in April 2015
https://www.npmjs.com/package/instantsearch.jsAlgolia is a search as a service company, and as such it is fundamental that developers can implement a new search as quickly as possible, correctly and with the least amount of learning on their hand.
InstantSearch.js is the first widget library offered by Algolia. The widgets are pre-packaged UI elements that are used for building the search UI. The library is made to be easily extensible. Over the time, InstantSearch.js has evolved and is now the core library for UI libraries specific flavors.
This library is a key asset for convincing developers to use the Algolia search engine, as it makes the UI implementation trivial compared to the competition.
