Identifying and solving architectural and operational issues in the team responsible for the SaaS platform offering.

Working with a fast-paced startup mindset, my missions are to: - Maintain and evolve the platform for our API Portal product. - Architect and build the new platform for our new AI Data Analyst product. - Lead the team on Cloud, DevOps, Security, CI/CD, and Software Developement best practices topics. Stack: AWS, GCP, Kubernetes, OpenAI, Pulumi, CDK, Terraform, TypeScript, Golang, MongoDB, Airbyte, Kestra, Github Actions, Dagger, ArgoCD, Argo Events, Argo Workflows.

Some highlights: - Accomplished onboarding trainings and certifications, including AWS-SAA & HCTAO-002. - Presented a breakout session for Solutions Architects called "Super-powers for Platform Teams: Declarative infrastructure with AWS Controllers for Kubernetes and Crossplane". - Worked hand-in-hand with the Account team and other internal stakeholders to bring maximum value to our customers. - Helped our customers decide and execute on all things AWS, with a focus on all things Containers !

In a Node.js micro-services and Vue.js micro-frontends environment, my missions were to: - Plan and execute the vision for the Platform roadmap. - Participate in application architecture decisions to provide expertise and solutions to developers and product teams. - Lead internal training and cultural aspects around DevOps, Cloud, Containers, Linux, Opensource and Automation ... - Create processes and tools towards better developer productivity and experience. - Increase team efficiency with smoother software delivery and deployments processes and tools. - Introduce and enforce best practices in all areas. - Design and secure Cloud resources. - Ensure the availability of the platform. Some projects highlights: - Migrated from EKS to GKE, and from mLab to MongoDB Atlas, re-defined all the Infrastructure as Code with Terraform. - Written a tool in Python for developers to automate the creation of new environments, both locally and in Kubernetes clusters in the Cloud, effectively bringing "Self service preview environments" for QA & Product teams to collaborate efficiently. - Implemented GitOps application infrastructure dependencies & cloud resources with Crossplane. Stack: Linux, AWS, EKS, GCP, GKE, Terraform, Kubernetes, Crossplane, Istio, Helm, Skaffold, minikube, Docker, Python, Pytest, Datadog, StackDriver, CircleCI, GitHub Actions, MongoDB Atlas ...

In a mostly Python environment, my achievements were: - Designed GCP & Azure VPCs using Terraform, wrote about 20 modules. - Created a fully automated docker-compose local developer environment around Traefik. - Led internal evangelization sessions about DevOps/Cloud/containers culture & tooling. - PoC about scaling Kubernetes workloads using Prometheus, prometheus-adapter & Kubernetes custom metrics API. - Wrote Helm charts and used helmfile/skaffold to run applications on both GKE/AKS. - Built a fully automated, yet configurable, local minikube developer environment. Stack: Linux, Ansible, Packer, Terraform, GCP, GKE, Azure, GitLab, Traefik, Docker, Kubernetes, Helm, helmfile, Skaffold, telepresence, Prometheus, Grafana ... Environment: Python, Django, Celery, PostgreSQL, ElasticSearch, Redis, rabbitmq, node.js, react, GraphQL, Yocto, mender ...

In a PHP environment, my achievements were: - AWS Cloud Design & Infrastructure as Code with CloudFormation. - Infrastructure CI/CD with CodePipeline. - Image-Based Infrastructure with Packer & Ansible. - Standardized developer environments with docker-compose. Stack: Linux, Git, BitBucket, Packer, Ansible, Capistrano, Jenkins ... VPC, IAM, EC2, S3, RDS, ELB, AutoScaling, CloudFormation, CloudWatch, Route53, SES, SNS, CodeCommit, CodePipeline, CertificateManager ...

In a mostly PHP environment, my notable achievements were: - Designed & built the Docker swarm. - Automated LEMP installation & configuration with Ansible. - Standardized developer environments with Vagrant. - CI with Jenkins, Deployments with Capistrano. - Replaced ProxMox & OpenVZ with KVM & Docker. - Reworked storage servers with a Synology HA Cluster. - Reshaped the multi-site network with multi-wan routers & firewalls, VLANs & VPNs. - Initiated the migration to Active Directory. - Domains, Mails, Users & Access management. - Purchases, providers & suppliers relationship. - Recruited & drove a bachelor student in network administration. - Day-to-day administration, monitoring, backups ... Stack: Linux, Git, GitFlow, Docker, Traefik, Prometheus, BitBucket, Packer, Vagrant, Ansible, Capistrano, Jenkins, KVM, ProxMox, OpenVZ, OpenVPN, IPsec VPN, OVH, Gandi, FortiGate, ZyXEL, D-Link, Dell, Synology NAS ...

In a full PHP environment, my achievements were: - Wrote CloudFormation stacks & led the complete migration to a multi-region, multi-AZs, image-based & autoscaled AWS cloud to serve the multi-hosting saas platform based on LAMP. - Led the modularization of the application from a monolith to a 3-tiered multi-services application. - Evangelized Git & multi-stage application development cycles. - Wrote a fully automated multi-origin (deb, rpm, source, pip, cpan, etc...) package manager & services installer in Bash. - Wrote an installation & configuration tool for the application modules in OO-Perl. - Interfaced with clients engineering teams to establish specifications & realize on-premises installations. Stack: Bash, Perl, Debian, Ubuntu, CentOS, RHEL, Gentoo, Git, Gitolite, Apache2 MySQL, PHP-FPM ... VPC, IAM, EC2, S3, RDS, ELB, AutoScaling, CloudFormation, CloudWatch, Route53, SES, SNS ...
