About Serdar

Cloud Architect – DevOps / DevSecOps
Technical Referent Kubernetes & Linux

Product teams move fast.
Infrastructure, on the other hand, often becomes complex, fragile, and costly to evolve.

The breaking point comes when the technical stack can no longer keep pace with the business: accumulating debt, security addressed too late, cloud costs difficult to control.

My positioning is clear: structure, make reliable, and secure demanding cloud environments without slowing down delivery capacity.

Cloud Architect specializing in DevOps / DevSecOps, with strong expertise in Linux and Kubernetes, I work with engineering teams in growth or transformation contexts.
The scope covers architecture, automation, security, and operations, with a long-term vision oriented towards maintainability, performance, and resilience.

The contexts encountered are often similar:
- Cloud migrations poorly defined that generate more complexity than value,
- Technical debt that slows down product teams,
- Insufficiently secured CI/CD pipelines,
- Kubernetes clusters that have become difficult to operate,
- Gradual drift of cloud costs.

The approach remains pragmatic and results-oriented.
Environments are documented, secured, and truly operable.
Architectural choices are assumed and explained.
Production deployments are anticipated to limit incidents, service interruptions, and hidden costs.

DevSecOps, access management, monitoring, resilience, and cost optimization are integral parts of the framework, with communication understandable by non-technical decision-makers.

If you are looking for a Cloud Architect who can structure your technical choices, secure your trajectory, and play a technical lead role, an initial video call can help define your challenges and quickly establish a clear action plan. I respond within 24 hours and can intervene quickly according to your priorities.

    LUXURY GOODS
    November 2022 - Today (3 years and 7 months)
    Neuilly-sur-Seine, France
    Mission Objective:
    Accelerate and make development and deployment cycles reliable by implementing aDevSecOpsapproach onMicrosoft Azure/ **AKS**, focused on performance, quality, and security, with data-driven (DORA) steering.

    Achievements:
    • DevSecOps Integration in Azure DevOps (CI/CD):Added automatic quality and security checks (SonarQube,Veracode SAST+SCA+ container scans) with compliance rules and threshold management to secure releases.
    • Industrialization of Infrastructure as Code on Azure (Terraform):Standardized provisioning through reusable modules/patterns, harmonized deployments, and reduced discrepancies between environments.
    • Automation of Provisioning via ServiceNow:Implemented arequest → validation → executionworkflow for automated and controlled Azure resource creation, reducing time-to-project and improving traceability.
    • Optimization of Azure DevOps Pipelines:Refactored and improved reliability (templates, best practices, secrets/variable management, step optimization) to speed up execution and reduce deployment errors.
    • Centralization of Application Logs in Elastic Stack:Collected logs usingFilebeatand set up a robust processing chain (Event Hub → Logstash → transformations → Elasticsearch) to enhance observability, diagnostics, and Dev/Ops collaboration.
    • Implementation of DORA Indicators and Quality Metrics:Defined and calculated the 4 KPIs (Lead Time, Deployment Frequency, Change Failure Rate, MTTR) to provide an actionable view of performance and facilitate decision-making.
    Technical Stack:
    Microsoft Azure, AKS (Kubernetes), Azure DevOps, Terraform, Docker, Linux, ServiceNow, Elastic Stack, Filebeat, SonarQube, Veracode.

    Paris, France
    Mission Objective:
    Design and industrialize a completeDevOpsplatform (CI/CD, containerization, IaC, observability) on **Microsoft Azure**, with AKS as the execution foundation, to improve deployment reliability, scalability, and time-to-production.

    Achievements:
    • DevOps Environment Design and Implementation:Structured the delivery chain and operational standards around Linux, Jenkins, and Azure/AKS.
    • Deployment of Multiple AKS Clusters:Set up Kubernetes clusters on Azure to ensure workloadscalabilityand **resilience**.
    • Migration and Industrialization on Azure:Contributed to cloud adoption (flexibility, better resource management, and cost optimization).
    • Infrastructure as Code & Configuration Management:**Terraform** for Azure resource provisioning,Puppetto standardize and maintain Linux system configurations,Ansibleto automate recurring operations and deployments.
    • High Availability and Ephemeral CI/CD:Implemented a containerizedJenkins HAchain with **Docker Swarm**, featuring ephemeral build agents (created on demand, executed on build, then destroyed) to enhance reliability, isolate executions, and optimize resource usage.
    • Observability & Application Flows:Deployed anElastic clusterfor log centralization and aKafka clusterfor application flow/event management.
    • Modernization of Artifact Management:Migrated **Nexus 2 → Nexus 3**.
    • Python Automation:Scripting to industrialize DevOps processes (tooling, operational tasks, CI/CD automations).
