Summary

I build platforms and stay to run them, each bigger than the last. At MHP, Porsche's IT consultancy, I created Data Core X, the managed Catena-X connector that 40+ companies now use to exchange data under enforceable usage rules; I designed it, wrote its core, priced it and hired its 20+ engineers. For a 3,000-engineer automated-driving programme I led systems-engineering tooling: CI/CD halved, Rust search over 100,000+ requirements in under 50 ms, and a requirements editor, built with AI agents in the loop, that cut a 15-minute edit to under a minute. Today I am laying the cloud-native foundation and the AI-driven delivery process for an EU logistics leader's 300+ SAP applications. Before that: a tax platform filing close to a million declarations a season, an IoT company I founded, devices down to the Linux kernel, and a data centre I racked in 2004.

Selected achievements

Newest first. Result first.

  1. 2026

    Cut a 15-minute requirements edit to under a minute for a 3,000-engineer programme. Built, with AI agents in the loop, a web editor over 100,000+ automated-driving requirements; every change lands as a reviewed pull request. Also halved CI/CD time and shipped a Rust search backend answering in under 50 ms.

  2. 2025

    Created a SaaS product from zero and took it to 40+ companies. Data Core X, the managed Catena-X connector: I designed the architecture, wrote the core service, set the pricing, passed three Catena-X certifications and hired 20+ engineers; Volkswagen Group connects suppliers through it.

  3. 2023

    Carried a tax-filing platform through peak season at over one filing per second. Architecture behind the white-label app for Buhl's WISO Steuer: close to 1 million declarations in one season, €5M+ revenue; led up to 25 engineers in 6 squads.

  4. 2021

    Built IoT products from kernel to cloud, then sold one. Custom Linux kernel for an ATM security device; founded GKW Technologies: smart-metering gateways for a water utility, and a digital-signage device and fleet platform sold to a company that added it to its portfolio.

  5. 2004

    Ran infrastructure before it was cloud. Built the DGN Teknoloji data centre from the racks up and launched a self-service hosting portal in 2004; later led the platform team at a top-ten hosting provider.

Senior Tech Lead

MHP – A Porsche Company, Cologne, Germany

Porsche AG's management and IT consultancy (about 4,500 people, about €740M revenue; acquisition by Tata Consultancy Services announced August 2026). Technical lead across five Volkswagen Group, Porsche and industry engagements, newest first.

  • Cloud
  • Data spaces & automotive
  • Leadership

Mandate 01Cloud-native foundation, EU logistics market leader — lead architect, ongoing

Scope: 300+ legacy SAP applications · cloud-native target platform · AI-driven delivery process

  • Designed the cloud-native target platform and reference service onto which the client's 300+ legacy SAP applications migrate; architecture decisions and migration plans live in the repository as code.
  • Set up a human-in-the-loop, AI-driven delivery process, agent skills, quality gates and review flow included, that stakeholders, developers and consultants all work through; coach two junior developers; migration waves start November 2026.

Mandate 02Data Core X — creator and product lead; advisor since 2026

Scope: 40+ companies onboarded · 20+ engineers hired · three Catena-X certifications · AWS (EU) and STACKIT · Cofinity-X and STACKIT marketplaces

  • Built the service from nothing: MHP hosts and operates each customer's Eclipse Dataspace Components (EDC) connector with certificate management, an SAP module, usage-policy enforcement and multi-organisation dashboards, on AWS (EU) and STACKIT, the Schwarz Group's sovereign cloud.
  • Designed the architecture, wrote the core service, set the pricing (from €100 per month), passed three Catena-X certifications and hired 20+ engineers in Germany and India.
  • 40+ companies onboarded; Volkswagen Group connects suppliers through it. Sold on the Cofinity-X and STACKIT marketplaces; provisioning takes minutes and a typical go-live about six weeks.
  • Led the certificate-management and SAP quality-management squads, and consulted customers through onboarding and customisation.
  • Built the live onboarding demo and ran MHP's booth at the Catena-X Readiness Fair, hosted at MHP Labs Munich in September 2025, with suppliers onboarded live in front of Volkswagen Group, BMW, Mercedes-Benz, Ford and BASF.

Mandate 03Systems-engineering tooling, CARIAD–Bosch Automated Driving Alliance — tech lead · until 2026

Scope: 3,000+ engineers · 100,000+ requirements artifacts · Python, Rust, GitHub Actions, Bazel

  • Led the systems-engineering tooling team of the Automated Driving Alliance, where Volkswagen's software company CARIAD and Bosch had 3,000+ engineers building the driver-assistance (ADAS) stack for all Volkswagen Group brands.
  • Cut a 15-minute requirements edit to under a minute. Built, with AI agents in the loop and human review, a web requirements editor over the programme's sphinx-needs corpus of 100,000+ artifacts in 1,300+ documents: instant search, guided editing with live validation, a creation wizard, and every change landing as a reviewed pull request linked to Azure DevOps. The syntax errors behind about 15% of documentation build failures can no longer happen; v1.1.7 ran in production with two phases delivered ahead of plan.
  • Halved CI/CD time through GitHub Actions and Bazel optimisation; wrote a Rust search backend spanning every project in the programme, answering in under 50 ms.
  • Programme concluded July 2026 with the stack delivered.

Mandate 04Analytics platform migration (Porsche) — tech lead and lead developer

  • Led the legacy-to-cloud-native migration of a Porsche big-data analytics platform to AWS, fed by shop-floor data and therefore production-critical; delivered and handed over to Porsche's own team.

Mandate 05Digital vehicle twin (Volkswagen Group) — architect and tech lead

  • Designed the architecture and built the MVP core of Volkswagen Group's digital vehicle twin: every Group data source combined into one graph database behind an access-controlled model of each vehicle and its parts, which brands and suppliers read while each keeps its own data under its own control.
  • Aligned stakeholders across the Group, presented the MVP and wrote the roadmap reports the follow-on was planned from; the engagement closed with the MVP delivered.
  • Career lead ("people counsellor" at MHP) for seven consultants and engineers: development plans, promotions, retention.
  • Contribute to bid teams: solution design, demos and proposals that won new clients.
