Role(s):

  • DevOps Architect

  • Product Owner (Scrum) (Telefonica GmbH)
  • Solution Owner Mobile and Transport (Swisscom Schweiz AG)
  • Project Manager (P&T Luxembourg)
  • Solution Integrator
  • Authorized Trainer (IBM Premium Partner)

Senior Consultant – DevOps Architect

Within serima I had the responsibility to design and implement a DevOps CICD best practice. This concept is now used for the delivery of solutions in all new projects. Every solution has its own ready-to-pull docker development environment, including unit testing capabilities. The “DevOps CICD Pipeline” itself (Jenkins, Nexus, GitLab) prepares the docker images ready for integration testing and deployment. In all cases using Infrastructure as Code (IaC) at its core.

 

Deployment methods encompass:

  • manually or on-prem Docker environment
  • AWS Cloud (ECS, EC2) using Packer, Terraform, and Ansible
  • Kubernetes (bare-metal, EKS, or EC2)

Senior Consultant – Business Developer Cloud Monitoring

Our team was tasked with delivering future business opportunities to our CEO. Part of the team was responsible for assessing market reports and conducting vendor communication. My responsibilities mainly targeted setting up proof of concepts of cloud solutions, which in turn directly enabled serima’s major client to move some applications to the cloud already.

 

Activities include:

  • Market analysis
  • Feasibility study (Professional Services or SaaS)
  • Setting up Kubernetes, AWS (EKS, ECS, EC2)
  • Setting up ELK Stack / Elastic Search, Splunk, Prometheus, Grafana

Senior Consultant – Service Management and Correlation (Root Cause Analysis)

  • As Senior Consultant I led complex projects in the larger Service Provider and Telco customers. Main focus area’s encompassed RCA correlation and Service Management architectures for both Mobile (LTE, UMTS, GPRS), IP, and Transport (SDH, WDM). The designs were mainly based on the IBM Tivoli Netcool framework (OMNIbus, Impact, TBSM, ITNM), with (open source) additions like edgeSuite, Pentaho PDI Kettle, and NodeJS solutions.
  • Activities include:
    • Support European customers (mainly Switzerland, Germany, The Netherlands, Sweden, Luxembourg, and Poland) to setup and/or enhance their Service Assurance environment to the constant changing managed services demand.
    • Setup and/or enhance the supporting ITIL processes as Change Management, Release and Deployment Management, Incident and Problem Management, and independent Test Management.
    • Leading responsibilities in project communication and planning, design, and implementation of the agreed upon solution using agile project management (Scrum).
    • Demo sessions and proof of concept (POC) in a controlled technical lab or within the customer’s environment.

Trainer
Facilitate formal IBM training (IBM Premium Partner) or tailored workshops, both on customer premises and formal training sites.

Bemerkungen

Summary

  • With more than 20 years of experience in the Service Provider, Telco, and Finance market I had the pleasure to work with the largest companies in Europe. As IT Solution Architect I enjoyed designing large scale monitoring solutions integrating IBM Tivoli Netcool with OSS, BSS and other (open source) monitoring systems.

 

  • While companies moved to the cloud, I've moved with them advancing to Cloud Architect using the same proven design principles. With my hands-on Cloud Infrastructure and Monitoring experience I can free up Application Developers by setting up the right cloud solution, design and implement programmatic deployments (CICD pipelines), and setup (microservices) application monitoring. This by fully leveraging Infrastructure as Code (Terraform, Packer, Ansible, Docker, Jenkins, etc). As a trusted advisor I’m also able to support Business Owners with making informed Cloud and DevOps decisions balancing the costs of a solution with business, process, and organizational requirements.

 

  • Being seen as a team player, I like to listen to people and try to understand their needs. Consolidate all thoughts, use a methodical and structured approach based on best practices to make it work for all parties (win-win). This can be as simple as a talk over coffee or a formal presentation with all stakeholders to present possible solutions.

 

  • In a constantly changing IT landscape, I understand that today’s knowledge can be old tomorrow. I like to follow new trends and educate myself with the latest best practices in the market. This enables me to continuously improve my role and responsibilities.
