Felix Faust

Senior Product Engineer for CTOs and product teams

I take digital products all the way to reliable operations.

I build new products from the ground up and modernise established systems. I own the product code, infrastructure, automated delivery, and monitoring, working hands-on with clear technical responsibility. Your team receives a production-ready service it can operate, or I stay involved for long-term maintenance.

Direct collaboration

You work directly with me.

I take ownership of a defined technical area, implement the critical parts myself, and hand knowledge and operations back to your team.

Where I help

Product ownership with platform depth.

Product engineering connects product decisions with implementation and operations. Platform engineering comes in when migration, delivery, or infrastructure is holding the product back.

Build and modernise products

Product Engineering

I connect product decisions with frontend, backend, integrations, and production operations, and take responsibility for the implementation.

Typical situations

  • A new product needs a reliable technical line from discovery through operations.
  • An established product needs modernisation without putting the business at risk through an unnecessary rewrite.

What I take ownership of

  • Product and technical discovery
  • Frontend, backend, APIs, and integrations
  • Production readiness, observability, and handover

A shipped product and a team that can continue the decisions, code, and operations.

Cloud, delivery, and operations

Platform Engineering

I stabilise critical phases at the boundary between application and operations without separating the platform from product context.

Typical situations

  • A Kubernetes, OpenShift, or cloud migration needs a controlled path.
  • A platform bottleneck is blocking an active delivery or modernisation phase.

What I take ownership of

  • Target architecture and migration path
  • Cloud runtime, IAM, policy, and networking
  • GitOps, observability, and operational handover

A platform that supports real applications and can be operated reliably by the team.

How I work

Reduce uncertainty, then deliver with confidence.

Each step clarifies the next decision and moves the system towards a clean handover.

  1. Understand

    Map product goals, users, teams, constraints, and production risks.

  2. Design

    Turn the findings into a technical direction, clear decision boundaries, and an implementation plan.

  3. Deliver

    Implement the critical parts across product code, integrations, delivery, and operations.

  4. Handover

    Document decisions, onboard maintainers, and reduce key-person risk.

About me

I make difficult technical decisions and implement them myself.

I work between product, software architecture, and operations. Technical leadership is valuable when it ends in explainable decisions, working code, and a clear handover.

  • Frontend, backend, APIs, and data models
  • Cloud, Kubernetes, delivery, and observability
  • Applied AI features and agentic engineering workflows
