Freelancer profile translated to English.

Description

As a freelancer, I help companies gain productivity on React and React Native.

I am involved in missions such as:

- Audit, consulting, technical decision support

- Training, coaching, and code review

- Architecture, technical foundations, and new project startups

- Migrations to React

- R&D and ambitious proof-of-concepts

- Technical support

- Setting up an effective testing strategy

If we work together:

- I will bring maximum value in minimum time

- I will be available as soon as possible in case of technical blockage

- I will not create lock-in: your tech leads must understand and approve the code, processes, and decisions made

- I will make it easy to end our collaboration, as soon as you feel confident to continue without me.

I work with several companies at the same time, and do not work in a conventional way.

I do not do full-time implementation missions (like staff augmentation). Instead, I help your teams iterate faster.

Contact me and we can discover together if I can bring you value.

Details on my React expertise:

- I have been working exclusively with React since the end of 2013, and intend to keep the focus on this technology in the coming years

- My way of working has allowed me to see many React projects for companies of all sizes

- Open-source contributor to many React projects (React-navigation, Expo, Redux, Redux-saga, Gatsby, React-Native-Web, Apollo, Storybook... and personal libraries)

- Over 50,000 points on StackOverflow

As a freelancer, I lead the development of the Docusaurus project for Facebook Open-Source (https://github.com/facebook/docusaurus).

Docusaurus is a static site generator that facilitates the creation of documentation and content sites, based on NodeJS/React (similarities with Gatsby).
It generates a modern single-page application from Markdown files, allowing you to focus on content.

With over 20k Github stars, it is one of the most popular Facebook open-source projects.
Docusaurus is used to build many documentation sites, such as ReactNative, Jest, Babel, Prettier, Redux, SAP SDK...

What I do:
- Lead the project
- Finalize Docusaurus v2: add missing features, especially versioning and i18n
- Migrate complex Docusaurus v1 sites to v2: ReactNative, Jest...
- Maintain existing code
- Mentor contributors (external, Facebook interns, and Major League Hacking)
- Daily management of an open-source project (releases, community, marketing, support, bugs...)

REAL ESTATE
April 2017 - Today (9 years and 2 months)
I am developing a complex native iOS and Android application for my client.

My client wishes to remain discreet for now. The application is similar to the "Uber" model, in the sense that it is a kind of geolocated marketplace, and is used by both "sellers" (drivers) and buyers (passengers).

For this application, I used the following technologies:
- React-Native
- ExpoKit / Intercom / OneSignal
- React-navigation
- Glamorous-native
- Redux / Redux-saga
- Fastlane

I contribute to all phases of this application.
- Specs, design, and UX
- Architecture, based on React-navigation and Redux
- Frontend development and use of the Java API
- Integration of native views
- Automation of Fastlane deployment (Apple TestFlight and Google Alpha/Beta)
- Monitoring and tracking (Sentry, OneSignal, Intercom...)

Contacted for a bug fix (not simple, I admit), Sébastien agreed to look at the code and then asked me for payment for the solution. However, I simply received an email vaguely indicating the problem (which did not allow me to fix the bug). To be objective, the code was far from ideal, but I find that the promise was not kept, hence my review.

Sébastien was understanding and responsive. Code audit completed on time and in full compliance with our expectations. Very good communication with our teams. Perfect! We highly recommend Sébastien :)
