About

BlueOps is me — and that is the point.

BlueOps is the engineering company of Tomasz Sulik. You work directly with the person who designs and builds the solution — no intermediaries, no handing the project on.

Platform architect — cloud, Kubernetes and AI systems

Who I am

I design and build cloud platforms on AWS and Kubernetes, and AI-powered systems — the kind that have to run in production, pass an audit and keep costs predictable. I work directly with clients: you talk to the person who designs and builds the solution.

My day-to-day is banking — currently the Kubernetes platform at Danske Bank. That is where my standard comes from: multi-tenant platforms with security built into the architecture, GitOps, policy as code, observability with SLOs and infrastructure automation at scale.

I take ownership end to end — from a napkin sketch to a production platform the team actually wants to use. I bring the same standard to AI work: secure data and inference paths, monitoring, and clear rules for what happens when the model gets it wrong.

There is no sales layer and no project managers — from the first email you talk to the engineer who owns the architecture and the outcome.

Experience

Where I work and have worked

Selected environments — as an employee and as a contractor. Company names describe the context of the work; they are not references.

  • Danske Bank

    Current engagement

    I build and run a multi-tenant Kubernetes platform on AWS EKS (Cilium, Karpenter, OPA Gatekeeper, Argo CD) and an internal developer platform that cut lead time for changes by more than half, including the groundwork for AI/ML services.

  • Credit Suisse

    Security department: automated rollout of authentication protocols, CI/CD and code lifecycle.

  • ING (Dell Technologies)

    Leading the automation team for ING’s global private cloud with a capacity of 25,000 nodes.

  • Kuehne + Nagel

    Automated infrastructure compliance testing (InSpec, GOSS) integrated with CI.

  • Coolblue

    Environments from development to production with full CI/CD and configuration management.

  • Investec

    System integrations and monitoring automation in a high-compliance environment.

How an engagement runs

  1. 01

    Conversation

    A short conversation about the problem, the context and the constraints. No commitment.

  2. 02

    Diagnosis

    Scope, risks and a plan — in writing, before anything is built.

  3. 03

    Delivery

    Iteratively, with a working part of the system after every stage.

  4. 04

    Handover

    Documentation and handover to your team. Ongoing support only if you need it.

Working together

Ways to work together

I fit what the team needs — from a few days of review to a longer contract.

  1. 01

    Contract role in your team

    I join your team as a platform architect or senior engineer — on a contract, for as long as you need.

  2. 02

    Delivery project

    A defined scope: from diagnosis to a working system in production, handed over to your team.

  3. 03

    Advisory and review

    A review of architecture, security, cloud cost or an AI idea — with concrete recommendations.
