Architecture for the AI era.
I design enterprise architectures that are ready for AI – and build the products that prove it. 15 years in enterprise IT across rail, logistics and government.
Three disciplines, one practice.
Enterprise Architecture
Target architectures, ArchiMate landscapes and integration strategies that survive contact with real organisations. arc42, iSAQB CPSA.
AI Systems & Agents
Agent orchestration, knowledge graphs and protocols – designed for governance, auditability and scale, not for demos.
Product Engineering
From concept to running product: TypeScript, PostgreSQL, cloud-native. Former CTO, still writing code.
Products I build, systems I shape.
Archilence
A digital twin of the enterprise IT landscape: source connectors feed a bitemporal, ArchiMate-compatible knowledge graph; an agent backbone answers, audits and acts on it.
Solution architecture for Austrian Federal Railways
Automating train routing and modernising the workstations of dispatchers – the people who set the routes for every train on the network.
I run my own infrastructure, publish my protocols as open standards and release tools under permissive licences. The open internet gave me my career; I intend to give some of it back.More about me
Matthias Posch, solution architect based in Vienna.
For more than a decade, I have designed systems for large organisations, including Austrian Federal Railways, a European logistics group and several federal ministries, and served as CTO of a YouTube SEO SaaS company. Today most of my time goes into a full-time architecture engagement with Austrian Federal Railways. Alongside it, I founded Archilence, which builds digital twins of enterprise IT landscapes.
Certified as an iSAQB CPSA, I am fluent in ArchiMate and arc42, and equally fluent in the code that brings them to life.
