About Jérôme

IT engineer for 15 years, I have worked on numerous projects.

Overall...

I know how to manage the development of an IT project from A to Z, across all layers (UI/DOMAIN/DB/API). I know how to manage/guide/coach/train a team. I know how to architect a project to achieve an efficient and maintainable solution.

Functionally, the domain I know best is tourism/travel, but I am open to anything :-)

In detail...

My main technical expertise is in Java/JEE. This is the stack I have worked on the most. I obtained (a few years ago) these two certifications:
- Sun Certified Java Developer
- Sun Certified Java Programmer
I have worked on large-scale projects using JBoss/Wildfly. It is likely that you have already used my code when booking your vacation :-)

I work exclusively remotely, due to my location. This has allowed me to manage a Scrum team, assist/train developers. I have also been able to work alone autonomously, depending on the context. The time difference puts me in a favorable position to intervene in the evenings on projects.

Furthermore...

I like well-tested projects. So as much as possible with unit tests, but this does not exclude integration tests (end-to-end - E2E tests). This is one of the secrets to success. It's not my main job, but I can help you implement good practices and find testers (with the help of Malt ;-)).

I have worked on Angular frontends. New features, refactoring, version migration. A great framework for B2B apps.

I have worked on PHP APIs, with Slim. It doesn't excite me, but I can help out.

Kotlin and Compose Multiplatform VS Flutter. I've touched on both, I haven't chosen my favorite yet :-). Nevertheless, I am convinced that this is the future of UI development.

    Joined Afidium as a senior developer, I took over the technical direction of the web team after one year.

    I was able to work on and organize development for several B2B solutions for travel agencies.

    The main challenges at Afidium were:
    - taking over a large codebase (often legacy) with a small team
    - establishing a proven working method with Scrum
    - change management
    - recruiting qualified developers
    - implementing innovative techniques supported by CIR

    TRAVEL AND TOURISM
    August 2012 - June 2018 (5 years and 10 months)
    Télétravail
    Took over a codebase from an external provider. It was (very) old Java, in EJB2.

    I had to take over the project, update it to a recent Wildfly (WF9), adapt the code for EJB3, debug and implement new features.

    I had full technical responsibility for the project. I received functional requests and handled everything up to deployment, including mock-ups, testing...

    Today, in 2021, the project is no longer maintained but still used. I think it's a well-amortized codebase :-)

    B2B AngularJS frontend, Oracle then MySQL database.

    Lots of interaction with external systems in XFT (Xml For Travel). So XPath manipulation in the DOM and XSL transformations.
    Java MySQL Oracle Database XML XSLT Deployment Unit Tests AngularJS
