What we stand for

  1. Legacy IT is the starting point

    We assess the existing estate objectively and build on it. The aim is an architecture that can be implemented step by step while operations continue.

  2. Planning for operations from the start

    Every target state has to be operable. That is why the operating concept, monitoring, documentation and clear responsibilities are part of it from the outset.

  3. Advising and delivering

    We develop concepts and help implement them. This includes project management and technical troubleshooting, even in critical phases.

  4. Making decisions traceable

    We record architecture decisions in writing, with criteria and rationale. This keeps them verifiable for management, internal audit and operations.

Mark Stempinski

„I judge an architecture by whether it holds up in operation. That is why I plan the handover to your team from day one.“

Mark Stempinski has worked in IT since 2014. He holds a B.Sc. in Computer Science and a B.A. in Business Management. From 2020 to 2023, he planned, built and automated a data centre with distributed sites for a technology provider, including vendor comparisons and infrastructure as code with Terraform and Ansible. Since 2022, he has been Managing Director and CTO of FlixHost GmbH. There, he built up and developed his know-how in data centres, networks, multi-cloud, operations and SLAs.

On 24 November 2024, he founded FlixConsulting GmbH as an independent company. It combines architecture consulting with delivery, project management and technical troubleshooting. His project experience ranges from introducing NetBox with migration from Excel at a federal authority, through secure CI/CD pipelines in air-gapped environments, to operating concepts for critical data centre infrastructure to EN 50600 and ISO 27001. It also includes large migrations and rollouts, such as a software rollout in more than 30 countries. He works in German, English and Polish.

How we work

Services and engagement models
  1. 01

    Analysis

    We survey systems, dependencies, contracts and responsibilities, and talk to the teams in operations. The result is a picture of the current state, with risks and areas for action.

  2. 02

    Target architecture

    We design the target state and the route to it: migration path, roadmap and sequence of steps, agreed with management, business units and operations.

  3. 03

    Delivery

    We break projects down into steps that can be tested and accepted individually. Each step builds on a verified state, not on assumptions.

  4. 04

    Handover to operations

    We hand over the operating concept, documentation and monitoring, and train your teams. The aim is operations that your team can manage on its own.

Commitments

What you can rely on

  • Confidentiality

    We do not name clients publicly, only industries. In the unlocked profile, names appear only with the client's consent. On request, we work under NDA.

  • Results for each phase

    Every phase ends with agreed results, such as a current-state analysis, target architecture or operating concept. You then decide on the next step.

  • Direct point of contact

    From the start, you speak to the consultant who is technically responsible for your project. There is no handover from sales to a project team.

  • Candid assessment

    In the initial conversation, we tell you whether and how we can help. If a task does not match our experience, we say so openly.
