About

Building, scaling, and consolidating enterprise platforms: that's what I've been brought in to do for the past ten years.

Tungi DangAI-native Technical Product Lead
Interim Head of Data & AI at Bahlsen Group · open to consulting

Embedded in engineering teams at Orcrist, E.ON, Allianz, Volkswagen, Bundesdruckerei, Nelly Solutions, and Telefónica. I take over backlog, discovery, and operating rhythm and stay until the team runs on its own.

Most recently at Orcrist, I led a GitOps / IDP platform for law enforcement on GKE. At E.ON, I put AI into production for 8M+ energy customers under KRITIS. At Allianz, I built developer self-service that cut cloud provisioning from over a year to days. At Volkswagen, I shipped the commerce backbone for five brands.

Before that, six years at Capgemini and Erminas, where I learned the fundamentals: software engineering, systems design, and delivery across fintech, retail, insurance, and aerospace. I studied welding engineering, computer science, health economics, and machine learning: research at four universities across Hamburg, Copenhagen, San Diego, and the University of Federal Armed Forces. Work in enough different worlds and you know the patterns.

How I work

Scalability

Platforms outlast the projects that build them. I put self-service infrastructure and golden paths in place so the tenth team onboards as fast as the first.

Reliability

Once a platform is live, people depend on it. I work where the decisions happen, incident calls included, and build the operating rhythm and playbooks with the team. A great platform was never the real goal. The goal is an engineering culture that sustains it.

Security

GDPR, BSI, KRITIS, Gematik. I've shipped under all of them. Compliance shapes the architecture from the first design decision. Retrofitting security late in the cycle always delays the launch.

Observability

I measure before I change anything, and I keep measuring after it ships. SLOs the team agreed to, traces that show what the platform is doing in production, a dashboard someone opens every morning.

Tools I work with

AI is part of how I think now, integrated alongside the product tools I've leaned on for years.

Industries

Across industries, the same patterns

Ten years embedded in regulated, large-scale organisations. Different sectors, the same problems underneath: platforms that need to scale, comply, and outlast the project.
