Dear Říha,

Thank you for considering my application and for providing the opportunity to elaborate on my qualifications. Below are my responses to your supplementary questions:
1. Motivation and Fit

What motivates you most about the DevOps Specialist role at WEDOS, and what are your expectations for this position?
I am motivated by WEDOS’s reputation as a forward-thinking technology company and its commitment to delivering robust infrastructure solutions. My passion lies in building scalable, automated systems, and I am eager to contribute to WEDOS’s DevOps initiatives using my expertise in Kubernetes, CI/CD, and monitoring. I expect this role to offer hands-on challenges where I can leverage my skills in infrastructure automation, optimize deployment pipelines, and collaborate on innovative projects that align with my goal of driving efficiency through DevOps practices.
2. Technical Experience and Projects
Project 1: Kubernetes & Helm Deployment at Tunisia Software Factory & BE|Softilys

    Role: DevOps Engineer
    Key Tasks:
        Helm Chart Management: Deployed and configured Helm Charts for microservices applications, MongoDB, and PostgreSQL databases.
        Kubernetes Automation: Ran automated tasks using CronJobs in Kubernetes clusters.
        Security & CI/CD: Built a personalized Trivy Docker image for container vulnerability scanning and integrated it into GitLab CI/CD pipelines.
        Scripting & Reliability: Developed Bash scripts for automated version synchronization across project files and implemented linting to fix syntax/indentation errors.
        Monitoring: Set up a Prometheus-based monitoring system to collect metrics from Kubernetes clusters, microservices, and infrastructure.
        Database Optimization: Improved MongoDB performance via advanced query profiling.
        Infrastructure as Code (IaC): Implemented GitLab CI/CD pipelines to validate and apply Terraform configurations.
    Outcome: Enhanced deployment reliability by 35% and reduced manual intervention through automation.

Project 2: CI/CD Pipeline Optimization at DOPIFY 

    Role: DevOps Engineer
    Key Tasks:
        Configured Docker image builds for microservices and published to Nexus.
        Automated feature delivery via GitLab CI/CD pipelines.
        Provisioned infrastructure using Ansible.
        Deployed monitoring systems with Grafana and Prometheus.
        Troubleshooting Kubernetes service connectivity issues.
        Implemented log rotation to save disk space.
        Created restricted users and managed group permissions via Ansible.
    Outcome: Reduced deployment errors by 25% and accelerated feature delivery.


3. Docker Image Management

I have extensive experience creating and publishing Docker images:

    Built and optimized images for microservices using multi-stage builds (e.g., at Geo-Tracking Group).
    Automated image publication to Nexus via GitLab CI/CD pipelines (DOPIFY project).
    Although I have primarily worked with Docker registries like Nexus, I have used Harbor a few times and am familiar with its core concepts. I haven’t worked extensively with Kaniko but am confident I can quickly adapt to it given my solid understanding of container image workflows. 
    Familiar with registry concepts and eager to learn Harbor or Kaniko if needed.

4. Monitoring and Infrastructure Optimization

    Tools: Prometheus (metric collection), Grafana (dashboards/alerts).
    Optimizations:
        Reduced MongoDB latency by 20% via query profiling (Tunisia Software Factory).
        Automated log rotation to manage disk space (DOPIFY).

5. Technical Challenge

Challenge: At Tunisia Software Factory, a legacy MongoDB deployment caused slow query performance.
Resolution:

    Profiled queries to identify bottlenecks.
    Optimized indexes and restructured queries, reducing latency by 20%.
    Implemented Prometheus monitoring to track improvements.

6. Authentication and Access Control

    Managed user permissions via Ansible (e.g., restricted users at DOPIFY).
    Configured Kubernetes RBAC for least-privilege access.(
    Developed a custom script to automatically generate Kubernetes RBAC manifests, significantly reducing time spent creating access control policies and minimizing human error)
    Eager to expand expertise in Keycloak or FreeIPA.

7. Linux Expertise

    Level: Advanced (5+ years).
    Practical Use:
        Administered Debian/Ubuntu systems for server management.
        Automated tasks with Bash and Ansible.
        Virtualization with VirtualBox and KVM.

8. Programming/Scripting Languages

    Bash: Automation scripts (version sync, log management).
    Python: Custom tooling and CI/CD enhancements.
    Terraform/Ansible: IaC and configuration management.

9. Availability to Work Onsite

Open to relocating to Hluboká nad Vltavou or other WEDOS locations.
10. Start Date

Available immediately (current role ended February 2025).
11. Salary Expectations

Competitive salary aligned with medior DevOps market rates in the Czech Republic.
12. Fixed-Term Contract

Yes, agreeable to an initial fixed-term contract with extension potential.
13. Preferred Employment Type

14. Why I Am the Right Candidate

I thrive in collaborative environments where innovation and automation drive success. My focus is on building systems that are not only efficient today but scalable for tomorrow. I am detail-oriented, proactive, and passionate about solving complex infrastructure challenges.
15. Interview Date
