In addition to my work on the web client, I supported the backend team by developing critical components in Python, including the first version of the media box (the storage server).

Digitick SA

September 2005, July 2012 (7 years - 5 years as CTO)

Digitick is the leading French e-ticketing platform for concerts, sports events, museums, and other cultural activities...

I joined Digitick in its early days as the second employee. By the time I left, it had grown into a robust group, having acquired two other companies (ZePass and Satori) and employing over 100 people.
Over the years, I developed and managed the creation of numerous features and services for digitick.com, catering to hundreds of major clients, including prestigious institutions like the Eiffel Tower...

Management

For five years (from September 2007 to August 2012), I managed a team of over 20 engineers specializing in web technologies.
As the head of the development division, I worked closely with team leads from other departments, ensuring seamless collaboration. I also maintained a strong partnership with the CIO to deliver optimal service quality.

One of the most challenging aspects of this role was managing projects that were consistently extremely urgent. The events industry (concerts, sports, etc.) is surprisingly disorganized, often waiting until the last minute to submit their requests, which meant deliverables were always developed under tight deadlines.
I oversaw a wide range of backends, interfaces, and specific services, continuously expanding our system while ensuring its stability and efficiency remained intact.

Coding

Here are some of my most notable projects:

I developed and/or managed a significant portion of our white-label ticketing platform.
The fifth version of this solution was used on high-profile websites such as the official sites of the Eiffel Tower and the 24 Hours of Le Mans.
This platform enables designers to deliver a fully functional ticketing system in less than two days by focusing primarily on its CSS.

Eiffel Tower Digitick.com 24H du Mans Olympique Lyonnais

I developed the prototype of an on-site ticketing kiosk, which was presented during the Eiffel Tower's tender process, and ultimately led to us winning the contract.
This prototype was a Single Page Application (SPA) designed to enable organizers to sell tickets on-site.
The solution, capable of managing various peripherals (printers, LCD displays, etc.), was later deployed across numerous points of sale, including the Eiffel Tower, stadiums, and national museums.

Ticketing spot

I developed the first three versions of our access control system.
Advanced MySQL tasks and PHP software were used to provide an embedded C-programmed terminal with a binary dump representing a complex data system.

The Digitick back-office is a comprehensive platform that enables event organizers to configure their sales, from simple quotas to numbered seating for large stadiums, with or without integration with external ticketing systems.
It supports CRM functionalities, advanced document generation, detailed data extraction, as well as real-time sales monitoring and management.
As the result of over 8 years of development by the entire team, I managed a significant portion of its features and functionalities.

Misc

During this period, I faced several interesting challenges, particularly on the production platform, including MySQL optimizations and database replication issues.
Working closely with the CIO was both highly educational and motivating. I genuinely enjoyed working on such a large-scale platform, which included 10 diskless front-end servers, 2 NetApp storage systems, and 2 database servers.

Engineering student

Inside Secure

September 2002, September 2005 (3 years)

Inside Secure (formerly Inside Technologies) is a startup specializing in RFID solutions, covering everything from processor design to fully packaged solutions.

I developed internal testing and benchmarking tools for chips, handling everything from PCB design to software and user manuals.
The most interesting project I worked on was an analysis solution for evaluating RFID chip performance before certification submissions. This involved coding an ISO 15963 frame analyzer.
