In an energy context, I'm working on a solution that allows GRTGAZ operators to control on a daily basis the Gas quality of a network. - Upgrade the tech stack to newer version to avoid security issues. - Complexe integration and E2E testing using aws LocalStack, test containers and Jupiter. - Preparation of Gas network caratography data with GeoJson web standard and upload output to AWS S3 bucket - Producing and consuming messages via kafka message queue for differents business workflows. - Integration with backend systems via REST contract and implemention of new REST services. - Definition of new AVRO contracts for event based communication between producers and consumers - Development of efficient and performante AWS Lambda for some business workflows

In a trading context I've worked on a micro-service that allow traders to qualify and validate there trades by storing justification documents with multiples types or emails into a global document handling capability and therefore keep and provide proof of trades on user demand. Technical challenges: - Implementation of OAUTH referesh token workflow to communicate with Microsoft Exchange using Microsot EWS API. - Securing sensitive data using Hashicorp VAULT as a KMS (Key Management System) and K8S secrets. - Implementing clean architecture to separate core business logic from implementation details and upstream/downstream dependencies. - Architecting the solution from scratch. - Externalizing application configuration using configMaps, Sercret , Volume mounts. - Applying SOLID principals between different components and layers of the project. - Implementing Sophisticated Exception handling. - Implementing Maven multimodules project to separate between client, domain and gateways. - Implementation unit and integration test to ensure the good maintainability and avoid regressions. - Prepare CI/CD scripts using Groovy, Jenkins and Kubernetes. - Making sure there's no configuration drift between different environment (even on local machine). - Github Flow enhancement, Code review using GitHub Soft skills challenges: - Pushing the team to embrace agility values and principales. - Moving the team from day estimation to complexity estimation. - International context (English used in a daily basis to collaborate with remote teams) - Ability to push and challenge the team towards sophisticated solution implementation Technical stack: Java SE 14, Spring 5, Spring Boot 2.5.3, Clean architecture, Maven, SOLID principals, Jenkins, Microsoft EWS API, Kubernetes, Groovy, Git, GitHub flow, Code review, Hashicorp VAULT, Microsoft office365, OpenApi Swagger, REST architecture, Jupiter, Mockito, Spring Boot IT, Web client Test for REST IT, Batch processing.
