Bridging strategy
with execution.

I partner with organizations that are serious about engineering excellence. I build high-performing engineering teams and resilient cloud systems.

The Three Pillars

My value proposition lies in the intersection of these three domains. I don't just manage; I understand the code. I don't just code; I understand the business.

Fractional CTO

Transforming engineering organizations through clear strategy, culture building, and operational excellence.

Principal Architect

Designing resilient, cloud-native systems that scale with business needs. DDD & Event-Driven Expert.

Fullstack Developer

From React to Rust. I don't just draw diagrams; I ship production-ready code.

Working Philosophy

Technical skills are commodities. The real differentiator is how we work. These principles guide every decision I make, from architecture to hiring.

01

Ship to Learn

Perfect is the enemy of good. I prioritize rapid iteration cycles to validate assumptions early, rather than over-engineering in a vacuum.

02

Choose Boring Technology

Innovation tokens are limited. I advocate for proven, stable stacks (Postgres, Go) for core systems to minimize operational risk.

03

Default to Async

Deep work requires focus. I build cultures where written documentation and asynchronous communication are the default, not meetings.

From my lab

My lab is where I publish the pressure, response, and value threads I use in serious work — constraint, design, and payoff in one readable arc. You see a few highlights here; the full catalog and longer notes live on My Lab.

Architectural

DDD Software Factory

Governed pipeline from domain model to code: DDD visualizer, 140+ structural diagnostics, canonical export, and a projector with conformance and adoption-drift tracking.

Problem

Teams treat code as truth while the domain model goes stale; manual translation from modeling to schemas and types loses alignment and is impossible to verify at scale.

Value

A working closed loop (model → diagnose → project → conform → observe) so structural intent stays authoritative and drift becomes visible before it ships.

Engineering

BCS · Behavioral Constraint Surface

Unified model for requirements as behavioral constraints (π, ω, φ, κ, s): continuous constraint surface, .bcs DSL, typed observation adapters, explicit temporality, from documentation to systemic diagnostics and CI gates.

Problem

Functional vs non-functional taxonomies fracture cross-cutting expectations; verification timing and tooling differ by label so the specification layer stops matching the system.

Value

A single spine from intent to measurement: progressive automation without rewriting constraints, and explicit handles for systemic diagnostics where capabilities overlap.

Limited Availability

Currently accepting Fractional, Advisory engagements starting May 2026.

Based in Munich

I only take on a few major engagements per year to ensure deep focus. Before we talk, please confirm we are aligned on the basics.

Prerequisites for Success

  • You are ready to invest in long-term architecture, not just quick fixes.
  • You have decision-making authority or direct access to it.
  • You value async communication and written documentation.
