Portfolio – Pascal Reitermann

About

I work at the intersection of platform engineering, messaging infrastructure, and developer enablement. My background includes operating large-scale event-driven systems in production, with a strong focus on reliability, security, and observability.

This portfolio is containerized and deployed on Google Cloud Run. It features an integrated AI Agent Mesh to demonstrate modern cloud-native patterns.

User queries are routed through Google Pub/Sub to a Go-based backend using Google Gemini. The system provides a real-time synchronous response while showcasing asynchronous event-driven flows (partially simulated for visualization) to illustrate how scalable enterprise architectures handle parallel tasks.

Hi! I'm Pascal's AI assistant. Ask me anything about his experience in EDA & Platform Engineering, his Open Source projects, or how this Google Pub/Sub powered agent works.

Agent Mesh Event Stream

> System idle. Waiting for events...

ℹ️ This stream visualizes the asynchronous event flow (Google Pub/Sub) behind this site. While the AI response is live, some operational events are simulated to demonstrate how this architecture scales in a production environment on Cloud Run.

DM is very pleased with Solace

This featured industry case study by Retail Optimiser examines the successful deployment of a Solace-based event mesh at dm-drogerie markt, one of Europe’s largest retail chains. It highlights the architectural shift toward real-time data distribution across stores and logistics centers. As a key engineer on this project, I helped implement the infrastructure that now serves as the 'central nervous system' for dm's supply chain and digital operations.

Securing Solace Metrics: How to Use OAuth with solace-prometheus-exporter

A technical deep dive exploring the implementation of OAuth2 authentication for the Solace Prometheus Exporter. I demonstrate how to secure sensitive monitoring endpoints by integrating modern identity providers, moving away from basic authentication toward a Zero Trust security model. The article provides a step-by-step guide on configuring both the exporter and the Solace broker to ensure that enterprise metrics remain protected

Event-Driven Integration at dmTECH: A successful migration and the path into real-time logistics

In this presentation, I shared insights into dm-drogerie markt’s large-scale migration to a modern integration landscape. I detailed the paradigm shift required to move from traditional messaging to a true Event-Driven Architecture (EDA) and the complexities of building a resilient multi-cloud environment. The talk focused on how we overcame enterprise-level migration challenges and outlined the strategic future of the Solace Event Mesh as the backbone for real-time logistics.

From Legacy to Multi-Cloud EDA: Selecting and Conception of a Modern EDA Platform

This session deep-dived into the strategic transition from a restrictive legacy messaging system to a modern, multi-cloud Event-Driven Architecture (EDA). I outlined our structured market evaluation process, where we benchmarked leading platforms against rigorous enterprise criteria. The talk highlighted how Solace emerged as the clear winner, followed by a successful Proof of Concept (PoC) that validated its ability to meet our complex operational and scalability requirements.
