Thinker, Problem solver, creativity

I am a passionate/developer advocado!

Problem solving innovation and new technologies are my main drivers I couldn't conceive my job without challenges or human interaction. I love helping and sharing with people I work with, also being part of at community of developers.

I am particularly interested by standards, as I believe their are the base of innovation and collaboration.

To promote the technology I work on, I have the pleasure to present at multiple meetups, in different countries. I am also keen on events like hackathon, as a participant or as aan organiser!

Oct 2017 - Present

Technical Lead, Open Banking Reference Implementation


Started this project as a POC, to demonstrate that Open Banking can be implemented using ForgeRock stack. After presenting it in London, OBIE contacted ForgeRock to partnership in building a model bank. Since it evolved as a SAAS offering for banks to hit the PSD2 deadline https://www.forgerock.com/open-banking-sandbox. It is also used as an Open Banking reference architecture for our ForgeRock customers.

The team has now grown significantly and my role as move to Open Banking expert and engineering technical lead.

We leveraged CI/CD best practices along with Kubernetes as a platform to deploy micro-services. We support the community that uses the sandbox via the official open banking slack channel.

Contractor, Bristol

Between the moment I quite my previous job and found my next role in ForgeRock, I had the opportunity to take a short contract with AKKA, my wife’s company.

AKKA is a sub-contracting company, working mainly with Airbus. The mission was to review their existing workflow/tool and propose a software solution more modern.

The mission scope was:

  • Collecting requirements from managers / engineers
  • Evaluating Open Source softwares to base the solution - We choose Redmine
  • Configuring and customising Redmine to answer the requirements
  • Presenting the solution to AKKA managements - successfully received
  • Deploying on service - high available

Initially used for their branch in UK Aeroconseil (50 employees), the solution is now deployed more globally in AKKA group with a dedicated engineering team.

Startup, Toulouse

Software engineer for a startup goodmorningplanet.com, a social network dedicated to travellers. I was in charge of the back-end algorithms for developing artificial intelligence. We used python with Django, based on Postgres SQL with Postgis. I worked on Graph algorithms and mathematical theory in order to improve user experience in our large database.

Unfortunately ended this adventure to follow my wife in England.

Living Objects

Backend Software engineer

Working as a Java engineer for a small firm, specialised in Network performance analysis for a French Telecom network. The backend had to manage a huge data computation, with high time constraints. My work was to design multi-threading software, with optimised algorithms highly performant, to handle large sets of data every seconds.

In a small firm like LivingObjects, principal engineers had to be polyvalent. My responsibilities covered: deployment in our client servers, leading back-end modules, developing R&D intelligence with a Phd Student, doing maintenances in different servers, helping recruiting and training new back-end engineers, participate in hardware architecture.

Last year of my master, as part of the student exchange program, for completing my master.

PolyMTL is allowing students to choose their courses. The courses I enjoyed the most:

  • PHD course in quality of software engineering.
  • Mobile development, building a game for android. From scratch to the android store
  • Embedded system, as for example implementing the logic of a router on microchip.
  • Virtual reality programming, on headset and multiple-screens projected on the room.
  • Distributed system, the efficiency of codes running in multi-core and different servers

Software engineer Degree, Grade A


ENSEIRB is part of the “Grandes écoles”, higher education establishments in France known to be highly selective, elite, and prestigious institution.

The master degree cover all aspects of software engineering, for instance:

  • Algorithm, Graph theory.
  • Cryptography.
  • >Advance networking concepts.
  • Quantum computing.
  • System programming.

Preparation programme for the “Grandes écoles”. The most challenging years of my education by far. The programme consisted of 1800 hours of courses in 2 years, which include the major subjects of the other university programmes:

  • Mathematics.
  • Physics and chemistry.
  • Mechanics.
  • Computer sciences.

At the end, students get a degree in the 4 above specialities

The best way to describe it is that you do the 4 licenses at the same time
