All about entrepreneurship, banking and blockchains ^^

Staff engineer Core Banking

Inside the core-banking team, I worked as a senior NodeJs BackEnd developer. My team is in charge of extracting the core-banking from the monolith app and develop from scratch the new banking micro-services architectures.  I had to develop and manage the micro-services (koajs, events, swagger-doc, unit tests and REST apis) hosted on aws and deployed with terraform. I modelized some of the data structures on PostgreSQL, Redis and prepared the event-sourcing architecture to facilitate the intregation of KafKa. I built a few features on the GraphQL API (with Apollo)

In the meantime, I had to worked on the frontend app web application in ReactJs which communicate through REST and GraphQL api to the backend services.

Staff engineer freelance

I gave advice on how to better design the architecture for the backend services to make them more reliable and scalable. Apart from this, I also worked on some web3 feature.

Consulting backend and ops freelance

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).

Backend developer freelance (senior)

I developed backend services for the ios mobile App Elityz. I created some REST APIs for the mobile app and I realized automated tasks for computing operations. I had to add external services mapping. I maintained the platform up-to-date and fixed bugs on a daily basis.

Backend developer freelance (senior)

I developed back services for the ios mobile App Elityz. The services was developed on firebase cloud functions (push notif, automatic matches between profiles, distance calculation,etc)

Front developer freelance

For this small mission, I realized a web administration application to handle mobile datas with the firebase framework and React/redux. I integrated the material-ui components to get a smoother visual user interface.

Backend developer (senior)

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.

Software engineer (junior)

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].
