2019 (Jan - Aou)
BNP CIB (freelance)
Backend/Frontend DevOps Engineer
Integrated in the IV2 marketplace team (nearly 30 engineers), I worked
inside the development team as a senior backend/frontend developer and
DevOps expert. My Scrum team which was compound of one product
owner, one scrum master, an agile coach and five developers was
committed to the scrum framework guidelines (Sprint planning, daily
meeting, sprint review & retrospective). We also used Kanban to reduce as
much as possible the bugs stock. My developer job was divided into two
main parts. Firstly, I worked, on a daily basis, on the sprint backlog items
implementing functionalities on the product backend (es6, nodejs, moving
from monolith to microservices, RESTFul APIS, JWT, mongodb,
postgresql, docker) and Front (ReactJs, webpack, babel), unit tests
(mocha, jest, commitizen, eshint). Secondly, I was responsible for the
DevOps methods for our team and had to set up/enhance the automated
build/deploy processes (CI/CD on Jenkins with groovy scripts, gitlab,
ansible, docker , rancher and kubernetes) and management the
platform tools (upgrade, experiments).

Inside the operational service team, I worked as a senior NodeJs BackEnd
developer for Frichti. I had to develop and manage many micro-services
(koajs, websocket and REST) hosted on aws and orchestrated with
kubernetes, docker. I modelize some of the data structures on PostgreSQL,
Redis and RabbitMQ, Bull to be compliant with the event sourcing and
CQRS. I needed to configure the CD/CI for my projects with automated
tools: Jenkins, scripts, circle-ci and test-units. I also deployed some of the
best practises of the codebase with eslint, docker-compose and ES6
features. On the other hand, I worked on a frontend backoffice web
application in ReactJs/Redux and webpack.

J2EE - Software Engineer
3 years term contract : Engineer in study and development.
My goal was to design and develop a Professional web application using
technologies based on RIA [J2EE/Flex / Hibernate] and
secure/authenticated services [SSO / LDAP] , to afford to make
deep defense on all application layers through auditable processes
and rights business operations and user interface features. The user
interface is shapeable through the business services that provide a list
module authorized for a user + profile + group. In addition, I contributed
to SCRUM project management tasks. [Hudson / Ivy + ant / svn / ehcache /
Junit]. I was able to make the weekly monitoring of developers’ tasks (daily
meeting) work for the realization of graphs and statistiquess providing
advanced project indicators (burndown chart, KPI, etc). I completed the
project management data recovery with innovative technologies being
force proposal [GWT / Talend].

J2EE - Internship
6 months internship study : Development of a rich internet application
[HTML / Flex / BlazeDS] and a secured, web services [SOAP / Axis 2] study
of an ETL tool [Talend].
In the first phase of study, I was asked to take the Talend tool in hand and
to understand the application and development methodology that I have
needed to put in place structure: the interface with the web server,
perform simple or multi-level jobs existing components and components
specifically developed and the choice of orchestration.
I also had to study the integration of Talend solution with tools developed
in the context of industrialization developments: version control, unit
testing, continuous integration, etc..
In a second phase of design / production, I was in charge of a mini-project,
which included a written Flex GUI, written in Java web services according to
the principles adopted during the study phase of server part. Particular
attention was given to the implementation of abstract services that allow, if
necessary, replace any service coded in java encoded by the same service
in another technology without having to review the calling code, the
GUI code in particular.

package to study the « Best Execution » [C # WPF / SYBASE / SQL SERVER /
ASP.NET / BLOOMBERG]
Design and implementation of a study of « Best Execution » package
In detail, the « Best Execution » must be able to allow recovery of the daily
values needed for calculations of performance indicators and store. The
application will calculate all the indicators in finding an alternative to
calculation errors. Finally, a graphical interface will return the consultation
of the data set. The consultation will be via a software man-machine
interface
