The hardest part of building enterprise platforms has nothing to do with the stack.

Building the observability platform at E.ON Digital Technology

Tungi DangTechnical Product Lead
Berlin

It's getting product and engineering to solve the same problem. One team thinks about users. The other thinks about uptime. I make sure they're building the same thing.

For the past ten years, I've embedded with engineering teams at E.ON, Allianz, Volkswagen, and Bundesdruckerei. Not as an advisor who hands over slides — as the person who joins the standup, owns the backlog, and stays until the operating rhythm holds without me.

My path here started in welding engineering. Then computer science, health economics, machine learning. Six years at Capgemini across fintech, retail, and aerospace before going independent. When you've shipped in enough different worlds, you stop seeing industries and start seeing patterns.


How I work

I embed, I don't advise

I'm in your Slack, your Jira, your incident calls. The only way to understand a platform is from inside it. Most of my engagements start with a week of just listening.

Compliance is architecture

GDPR, BSI, KRITIS, Gematik — I've shipped under all of them. Regulation isn't a gate at the end. It's a design constraint from day one. Always cheaper that way.

Platforms, not projects

A project ends when the deadline passes. A platform has users who depend on it long after you leave. I build self-service infrastructure, golden paths, and playbooks — things that get better without me.

Teams, not systems

The goal isn't a great platform. It's a team that doesn't need me anymore. I install the operating rhythm — SLOs, runbooks, governance — not just the technology.


Selected engagements

E.ON2024 – 2025
Observability Platform

Six monitoring tools, zero shared language for incidents. Built one OpenTelemetry platform that replaced them all. New domains now onboard in days, not months.

6 → 1 tools consolidated
Allianz2022 – 2023
Cloud Platform Engineering

Getting a cloud environment took over a year. Built developer self-service with compliance baked in. Same thing now takes weeks.

~80% faster provisioning
Volkswagen2022 – 2023
Commerce Platform

Five brands, five ordering systems, no shared inventory. Built the commerce backbone that unified them. 1M+ users now see real prices and real stock.

1M+ active users
Bundesdruckerei2023 – 2024
Sovereign Data & AI Platform

Every ministry was building its own data platform from scratch. Designed one sovereign platform they all share. Production-ready v2.0.
