Experiences

Piana is a neobank dedicated to modern fleet. The project has been started from scratch, which allowed us to carefully choose the components of the technical stack. We decided to use TypeScript, NestJS, fp-ts, React and Next.js. The next challenge was to integrate various services like Swan, Plaid, Defacto, Zizy, Auth0, Bridge etc, and to make them work together as smoothly as possible.

Swan is a Banking-as-a-Service platform. As a part of their team, I was in charge of improving and securing the API for new customers onboarding. I also participated in improving the project creation API. Swan used fp-ts a lot, and it was a great discovery for me. This library allows the use, in TypeScript, of functional concepts such as applicatives or monads. It was an excellent opportunity for me to put my knowledge into practice in this area: rewriting parts of the API in a more functional way, introducing functional concepts to the tech team, developing a data validator using applicatives…

The green data is a decision-making platform for regenerative agriculture. My task was to run a simulator written in Python by data scientists in a web browser using Pyodide, a Python interpreter based on WebAssembly technology.

Tokeny provides an enterprise-grade infrastructure to allow companies and financial actors to compliantly issue, transfer, and manage assets on blockchain, enabling them to improve asset liquidity. My task was to improve the React components of the admin panel. The graphics layer was based on MaterialUI.

Colas is a French public works company. I worked on developing an interface for their CRM Serena. This interface was used by several sub-projects which were also assigned to me later:

• a Node.js script for synchronizing data with a Microsoft SQL Server
• a JSON order management API

Most of the tools were developed with TypeScript and Node.js.

• integrate a SaaS authentication solution (Okta)
