Tadaweb is an build an OSINT platform which purpose is to make the world safer by empowering the human mind with the right information at the right time.

• build and enhance existing core infrastructure of the platform (such as VPCs, databases Postgres - Mongo - Redis, image registries, […]) with Terraform for GCP/Azure/AWS
• deployment and management of ~15 Kubernetes clusters on a daily basis. Clusters are both provisionned using Cluster API (for self managed clusters) or directly through Terraform for managed clusters like GKE
• working with custom images (build with Packer) for nodes to ensure immutable infrastructure and hardened security/compliance restrictions
• gather observability data like metrics, traces and logs to collect SLIs and write meaningfull SLO using tools like Fluentbit, Fluentd, Loki, Elasticsearch. Kibana, Prometheus, Grafana, Tempo/Jaeger, Thanos
• deploy smart alerts on gathered metrics to act fast whenever a component is detected faulty and document with post mortems what happened, how we solved the issue and what to do next to not repeat the same errors
• use Ansible to configure specific VMs not linked directly to the main platform
• implementing continuous deployment using GitOps model with ArgoCD
• building a library of GitLab CI templates shared amongst the dev teams to boost productivity and standardize image building (Kaniko, Buildah), image scanning (Trivy, Grype), image signing (Cosign) and binary authorization (Kyverno)
• development of multiple tools in Golang to solve some of our platform challenges such as a Terraform provider, some CLIs, services that interface directly with the Kubernetes API
• development of ‘glueing’ tools made in Python to link multiple steps of a process (e.g. Terraform with Ansible)

Small mission for helping some of my colleagues at Sfeir to migrate one of our client from Amazon AWS to Google Cloud Platform (GCP). I have put in place their workload in a fully managed GKE. (Google Kubernetes Engine)

• Google Kubernetes Engine
• Cloud Build | Container Registry
• Java/SpringBoot | Angular/TypeScript

Aware of their change and run problems, ING has a big objective of developing their infrastructure and processes. To let teams be more autonomous and manage releases and incidents linked to their assets, ING entrusted me with the creation of an OPS unit and the deployment of the movement. This action is initiated by the Tribe Daily Banking & Lending Engine and extended to all the bank’s services. Apart from that, I have been working for a huge migration project at ING Luxembourg that completely refactor the existing payment processing thanks to my Java seniority.

• Set up a guild dedicated to the movement, to spread the DevOps culture within ING.
• Implementing tools such as Jenkins for packaging, Ansible for infrastructure as code, ELK (Elasticsearch, Logstash, Kibana) for logs aggregation and service liveness.
• Evangelization of the DevOps model and implementation of the strategy.
• Helping on development of the PSD2 European directive.
• Huge migration of the SWIFT payment platform to the ING group payment platform that runs thousands of daily payments.

Migration of a legacy trading application made in Java QT Jambi for the frontend with Spring 3 backend applications. We have been migrating one financial product at a time from a monolithic perspective into microservices and micro frontends applications using Spring Boot 2 and Angular 6.I wrote a complete Groovy framework for our needs using Jenkinsfile for pipeline as code. We used XLDeploy from XebiaLabs to deploy applications in our environments. I have propagated the idea of using Docker by providing them a proof of concept of the technology. Also, I have developed a complete CI/CD pipeline for Angular application since no native solution for building and packaging components libraries were existing at this time.

• Migration of a legacy trading application written in Java QT Jambi into a brand-new web application made with Spring Boot | Angular.
• Guiding and building some continuous delivery system for both Java and JavaScript technology (compilation, test, release, publishing, deployment) using Groovy, Jenkins pipeline (infrastructure as code) and writing a shared library.
• Advising transversal architecture team about how to use Docker and doing some POC with Spring Cloud integration.

Development of a document management platform used by jurists and lawyers to aggregate laws to make them more readable and user friendly. I was assigned the task of developing the desktop publishing application to print consolidated rules as books.

• Development of a DTP (desktop publishing) application in order to manipulate legal text. (consolidation, reference, reordering, …)
• Extraction of this consolidated data and transformation into a specific format intended to be released by a printer-publisher.
