Komlan Florient DOGBE
Senior Cloud & SRE Engineer with 6+ years crafting resilient, automated, and scalable infrastructure. Passionate about OpenShift, Kubernetes, Ansible and DevOps culture.
Projects
Missions delivered in production environments — confidential client contexts, real technical detail and real outcomes.
Enterprise OpenShift Platform — bare metal & AWS
Design and delivery of a production OpenShift platform (3 masters / 2 workers), UPI and IPI deployment on bare metal and virtualised infrastructure (Proxmox, KVM). Secure multi-tenant authentication via Keycloak, GitLab and LDAP, legacy application migration to cloud-native.
56+ Server Migration — CentOS End-of-Life
Led, with a team of 3, the migration of dev/test/prod environments (56+ instances) following the end of CentOS maintainability. Automated deployment with Terraform and Ansible for reproducible, consistent infrastructure across all environments.
PostgreSQL IaaS → Azure Managed Instance Migration
Led the migration of a PostgreSQL database hosted on IaaS to a managed Azure Database instance (SaaS), with monitoring and log management (Datadog) to improve scalability, resilience and operational efficiency.
AWS IaaS Infrastructure Audit & Redesign
Full audit of an existing AWS IaaS infrastructure, proposal and implementation of a cloud architecture aligned with scalability and security best practices. Migrated a Microsoft SQL Server database to Amazon RDS, with complete architecture documentation.
About Me
I am a Senior Cloud Infrastructure & Site Reliability Engineer with over 6 years of hands-on experience designing, deploying, and operating enterprise grade cloud-native platforms.
My expertise spans OpenShift / Kubernetes cluster lifecycle management, Ansible Automation Platform, cloud services management (AWS and Azure), GitOps pipelines, and observability stacks. I thrive in mission-critical environments — railways, defence, finance — where reliability is non-negotiable.
I am RHCA-certified with specialisations in OpenShift Administration, Ansible Automation, Linux Diagnostics, and Containers. I enjoy sharing knowledge through technical writing and mentoring peers.

Experience
- Automated deployment and management processes in development, testing and production environments stages using Terraform and ansible, ensuring consistent, reproductible infrastructure.
- Lead enhanced application performance through the implementation of monitoring and log management tools with Datadog.
- Lead the migration of IAAS PostgreSQL database to an azure database managed instance (SAAS), improving scalability, resilience, and operational efficiency.
- Due to the remove of maintainability of centos, I have lead migration of development, testing and production environment (around 56 plus instance) with teams of 3 people.
- Leads community meeting, contributed on troubleshooting cases, and help our team to grow in ansible automation management topic.
- Designed and delivered enterprise OpenShift platform across bare metal and Aws, Architecture base on production-ready kubernetes solutions (3 Master Node and 2 Worker node).
- Architected and implemented OpenShift deployment base on UPI (User Provisioned Interface), IPI (Installer Provisioned Infrastructure) on Bare Metal and virtualized infrastructures (Proxmox,KVM).
- Lead application onboarded and migration to OpenShift, helping teams transition from legacy environments to cloud-native architectures.
- Implemented OpenShift authentication and authorization strategies uging KeyCloak, Gitlab and LDAP, ensure secure and compliant multi-tenant environments.
- Played a crucial role in an AWS cloud migration project (Define process, advantages, result in human experience).
- Use ansible yaml and role to automated administration and configuration processes.
- Analyzed security risks and actively participated in incident management.
- Conducted a full audit and redesign of AWS IAAS infrastructure, proposing and implementing best-practice cloud architecture aligned with scalability and security standards.
- Conducted Microsoft SQL server database migration to Amazon AWS RDS.
- Ensured thorough documentation of architecture, configurations, and procedures to improve maintainability.

Services
Built on 6+ years in mission-critical environments (railways, defence, finance) — from architecture to day-to-day operations.
Cloud & OpenShift Architecture
Design and delivery of production OpenShift/Kubernetes clusters — bare metal (UPI/IPI) as well as virtualised (Proxmox, KVM, VMware) or cloud (AWS, Azure). Secure authentication and multi-tenancy with Keycloak, LDAP and GitLab.
Automation & Infrastructure as Code
Ansible Automation Platform automation (roles, collections, Execution Environments) and Terraform across fleets of dozens to hundreds of servers. GitOps pipelines with ArgoCD/Tekton, CI/CD with Jenkins & GitLab CI.
SRE & Observability
Setting up monitoring and log management (Prometheus, Grafana, Datadog, ELK), defining SLAs/SLOs and incident-recovery strategies — with measured results (backup RTO cut from 6h to 20 min, 99.9% SLA maintained).
Cloud Migration & Modernization
IaaS infrastructure audits, database migrations to managed services (AWS RDS, Azure Database), and Linux fleet migrations (e.g. CentOS end-of-life → RHEL) without service interruption, working in a team.
