Project 1: Migration 3DSv1 to 3DSv2

the migration of the 3DSv1 (card payment) authentication mode to 3DSv2 where we had to adapt to the regulations in force (DSP2) and implement the various cinematics linked to this change.

Project 2: PCI-DSS Certification

We managed to obtain PCI-DSS certification after passing an audit which confirmed that we comply with the PCI-DSS standard.

Project 3: Creation of a webhooks system

We developed a webhooks system from scratch which allows merchants to be notified of the various events that occur at the heart of the system (Transaction accepted, Mandate signed, Payment failed, etc.)

All these projects were developed using the scrum methodology, following the best development practices (code reviews, unit/integration tests, etc.).

Project 1: improvement of the search engine

The search was based on ElasticSearch for search results tolerant to errors and I improved the indexing for much more relevant results even if the user makes a mistake in entering the product searched.

Project 2: Gift List system

Creation from scratch of a birth list system (Piggy bank allowing the purchase of products on the site)

Project 3: Multi provider management

Switching from single-stock to multi-stock site management. (Structural change of the Backend and the Elasticsearch data structure)

Initially, the products on the site were supplied from a single source which was fixed in the code and the system had to be redesigned for management tolerant to a multitude of sources.
