I am working as hands-on software architect to design and implement a new NeoBank and BAAS(Bank as Service) from scratch. The solution is designed around event driven and CQRS using kafka ecosystem(Kafka, Kafka Streams, Kafka Connect, Schema Registry) and deployed as micro-services on GKE. I support around 20 squads( around 200 people) on different subjects mainly distributed processing challenges, kafka, kafka streams, spring-kafka and the effective way of implementing various patterns mentioned before and others like Circuit-Breaker with kafka consumer. I keep running some training sessions and code examples to help them grasp and understand kafka components, exactly once processing and 1PC best effort. The solution uses exactly once processing whenever possible, and 1PC best effort for some use cases that involve external DB with synchronous calls to third Party APIs. I work also on: - Defining and deploying schema governance process around schema-registry, avro and gitlab-ci. - Deploying and securing applications using Keycloak as an OpenId Connect provider. - SCA component for strongly authenticating customers from mobile application - SSO with external partners - Implementing a generic library for using kafka as an event store for event sourcing application - Help to introduce CDC for some part of the system - Structured Concurrency usage for purging data (GDPR) Technical stack is around GCP, GKE, Confluent Cloud, Java 23, Spring Boot 3, Webflux, Spring kafka, Kafka Streams, Kafka Connect, Schema Registry, Helm, Terraform, GitLab-ci, ArgoCD, Vavr, testcontainers, Swift, Android

I worked as software architect/senior developer to implement and deploy two main projects around Blockchain: - PokenIDP: An OpenId Connect provider relying on Ory Hydra to secure all internal and Partner's applications. - PayWithPoken: A secure protocol to allow payments, mainly ERC-20, from any Partner website. - Designed and Automated the process of creating AWS VPC, sub-nets, NLB, kubernetes cluster with Terraform - Automated deployment of all applications using Helm. Technical stack: GO, NodeJS, NPM, Ory Hydra, AWS(ec2, s3, NLB, VPC, subnets, Internet Gateway, EKS, ECR, Api Gateway, PrivateLinks, CloudWatch, Autoscaling groups), Terraform, HELM, Docker, Docker-compose

Worked as Software Architect and Tech Lead to design and implement FIRST project(Fileact, Interact Routing Secure Transport) from scratch. It's a secure, resilient, scalable routing platform with builting audit trail, for exchanging financial flows (Fileact, Interact ....) between BNP backoffices and SWIFT counter parts using SWIFTNET. The platform is distributed, asychrouneous and relies on already deployed solutions like IBM MQ, CFT Transfer and MongoDB. It uses 1PC best effort with transactional outbox to ensure atomicity and scalability without even considering solutions like XA 2PC(that doesn't work and mongodb doesn't even support). The solution uses hexagonal architecture with an immutable domain model, microservices, spring integration, ibm mq, mongodb, CFT, vavr, jqwik, docker, docker-compose.

Member of Phenix project's core team, responsible of designing and deploying a new real time BigData platform. The core team is also responsible for setting up the architecture and implementing all tricky parts to help other developers design data flow pipelines to implement business relevant use-cases like real time stock calculation. The platform relies on Kafka, KafkaStreams, Fs2, Cats, Cats-effect, Kubernetes, GCP, HDFS, Scala, Spark, Kustomize.

Worked as Lead Devops/Architect on the SmartBrics project, a media planning solution. I was responsible of: - Deployment of the solution worldwide (US, BE, ES, DE, DK ...) - Tunning the platform (JVM, GC ...) - Advise on the architecture and development best practices Technical stack: Kafka, AWS, Ansible, Kubernetes, Docker, Shell, MySql, Haskell, Scala

I was responsable of defining and setting up the architecture of Geobus EService project. The project aims to gather all data related to customer’s orders lifecycle across GEODIS business units and then offer a single entree point portal to manage them. Technical stack: Kafka, Cassandra, ElasticSearch, MongoDB, Mqseries, Java, SpringBoot, Haskell

Architecture Audit and recommendations

Responsible of Software factory division inside CACIB (Credit Agricole corporate & investment bank). I’m responsible of defining the architecture and validating all development and also developing some tricky parts that needs some high skills and experience on development. I’m also responsible for performing profiling and performance testing on deployed software and propose some enhancement and optimization in order to support growing users, response time and so on.

Worked at Sfeir, Astek, Valtech and Zenexity
