– Prepared the architecture for the web cloud dashboard application using VUEJS, AWS AMPLIFY, and set up the ci/cd for the stack, we used COGNITO for managing authentication and APPSYNC as api interface to take advantage of types codegen since we use TYPESCRIPT in the frontend app. – Created and Authored API's for backend Services for the mvp. – Integrated lambda functions to add more customisation and implement extra logic to appsync. – Assisted in testing and support of the application.

– Assessed and Created a subscription module using STRIPE, EXPRESSJS and MONGODB that supports plan upgrade/downgrade and unsubscription. – Migrated Mobile Application core REACT NATIVE from 62 to 67 using the UPGRADE HELPER. – Refactored the existing codebase based on best practices. – remade web back-office to be full responsive,ergonomic and user friendly using CHAKRAUI.

– Designed the system with a non-functional parameter in view, such as configuration, logging, parameterization. – Conceived a generic module that renders ui forms and widgets from json served from backend using server side rendering using NEXTJS, TYPESCRIPT, and REACT-HOOK-FORM. – Introduced testing for every layer of the project by adding unit testing using JEST and REACT-TESTING-LIBRARY, CYPRESS for e2e tests and NEWMAN for api testing. and forced a threshold of 70% (code coverage). – Streamlined CI/CD using GITLAB-CI/CD to perform build and run test and security audits checks for continuous integrations and deploy after successful integration in correspondent environments for continuous delivery.

– Designed and implemented a generic api test generator using EXPRESSJS and HTTP PROXY MIDDLEWARES that will proxy api requests incoming from end clients to the server and will write test from NUNJACKS TEMPLATES with javascript extension that will be run MOCKA and CHAI – Developed a Connector using typescript to consume 4D REST engine and replace the native datastore object provided by WAKANDAJS. – Changed all the codebase within WAKANDAJS that rely heavily on the SYNCHRONOUS DATASTORE with asynchronous code using the connector. – Replaced the SYNCHROUNOUS STORAGE with a asynchronous system that uses REDIS for cashing. – Migrate Graphql architecture to nodejs from wakanda and converted all resolvers to be asynchronous.

– 4D Professional Services is one of the most important services of 4D Corporate the rise of a tool to centralize the saas products used internally by 4D ZOHO CRM to manage client relationship (leads/sales ...) and ZOHO PROJECTS as tool for project management. 4D projects is a home made tool that uses rest ap exposed by both services to give a global view both in timeline and in process of different aspects such as project validation, resources evaluation,automated tasks, reporting. – I choosed the MEAN mongoDB as database, express as nodeJS framework for backend code, ANGULAR as frontend framework and nodejs as the application runtime of the application

– To lower maintenance costs and coding a new version for 4D FORUM I was in charge of doing a benchmark study of different saas products alternatives,one of the candidates I suggested was adopted for several reasons(features/pricing) is DISCOURSE – Once the solution is chosen the purchased plan didn't include the migration I took in charge migration process. mapping all the properties of existing data with discourse model. using nodejs scripts for reading the exported csvs I processed data and adapt it to be used later in discourse data insertion. – Followed the GUIDE OF INSTALLTION I setup my local environnement to execute my data insertion using DISCOURSE REST API the migration should include all languages and keep user experience seamless by keeping the same accounts and notifying active members with the new portal 4D DISCUSS

– Animated technical workshops on how to use REACT BOILERPLATE. the boilerplate offers a lot of tools out of the box such as Internalization, Seo and a predictable state management using redux and redux-saga. – Design and Architecture proof of concept integration of React in 4D Ecosystem
