## About

*Tech expertise + high-performance teams + 0-1 products that drive B2B growth*

### I build product teams that ship.

From enterprise AI to industrial IoT to energy.

Hi, I’m Andrej. I like bringing great people together to build products customers use and enjoy, and taking an idea all the way to a working business is what I love most.

At [T-Systems](https://andrejschreiner.com/#experience-t-systems), my team and I built [AI Foundation Services](https://docs.llmhub.t-systems.net/) from scratch. Today it serves 300+ enterprise customers and is growing triple digits year on year. Companies get 30+ open-weight models through one API, running on AI Factories in Germany, and since July that includes frontier models like GLM 5.2 on our NVIDIA Blackwell fleet in Munich. I own the product, the team and the business, and I stay close to the engineering and to our customers.

Before that, at [Cumulocity](https://andrejschreiner.com/#experience-cumulocity), I built software that helps companies run wind farms, automate production and predict equipment failures with IoT and machine learning. That included managing fleets of industrial devices and updating their software remotely. I also started [thin-edge.io](https://andrejschreiner.com/#experience-thin-edge), an open-source Rust framework that connects industrial devices to the cloud and manages the software running on them.

I work best with people who know their stuff, speak openly and follow through, and I always enjoy hearing from engineers and founders about what they’re building.

## Case Studies

*Deep dives into products I've built*

### AI Foundation Services on the Industrial AI Cloud

*Category: AI · T-Systems | 2024-Present*

**Problem:** European enterprises needed frontier LLM capabilities without renting US hyperscaler stacks — data residency, compliance, and production inference on owned infrastructure.

**Approach:** [AI Foundation Services](https://docs.llmhub.t-systems.net/), an OpenAI-compatible LLM platform: models on Telekom infrastructure in Germany, frontier models in the EU. Aligned to Deutsche Telekom's [Industrial AI Cloud](https://blogs.nvidia.com/blog/germany-industrial-ai-cloud-launch/) with NVIDIA, including early model serving on the Munich Blackwell fleet.

**Results and proof:**

- 300+ enterprise customers across healthcare, defense, automotive, public sector
- Triple-digit year-on-year growth
- 40+ engineers and researchers, #4 open-source AI project in Telekom ecosystem
- Early serving of frontier open-weight models (GLM 5.2) on the [Munich Blackwell fleet](https://www.linkedin.com/posts/andrejschreiner_frontier-ai-used-to-mean-renting-from-a-handful-activity-7478378242182303744-BDfW). My team tuned serving against replayed production traffic: median time to first token down 18x (246s to 13.3s), p99 from 728s to 67s, and peak throughput of 442 tok/s/GPU, up from 153.

### Cumulocity IoT Edge

*Category: IoT · Cumulocity (then Software AG) | 2019-2023*

**Problem:** Industrial customers needed edge IoT but existing solutions required deep technical expertise.

**Approach:** Self-service deployment for OT teams. Reduced dependency on IT provisioning.

**Results and proof:**

- 125% year-over-year revenue growth
- FIPS/DISA-STIG compliant variant — 2nd largest NA deal in 2021
- 5G Private Network projects with 5 leading telcos
- Gartner Leader (IIoT MQ 2021), Forrester #1 IIoT Wave (2021), MachNation Edge (2022)

### thin-edge.io

*Category: Open Source · Open Source | 2021-2023*

**Problem:** Device teams waste time building custom embedded code for cloud connectivity, certificate management, and device management — locked to one vendor.

**Approach:** Lightweight, modular, cloud-agnostic framework (~28k LOC Rust). Runs on ≥16 MB RAM brownfield hardware. Full device lifecycle: provisioning, OTA updates, remote access. Apache 2.0 license.

**Results and proof:**

- v1.0 with production deployments at industrial OEMs
- Cloud-agnostic: AWS, Azure, [Cumulocity IoT](https://andrejschreiner.com/#experience-cumulocity)
- 12 co-innovation agreements with early adopters
- Community with public meetups, project governance model

### E.ON Optimum

*Category: Energy · E.ON | 2016-2019*

**Problem:** Commercial building operators wasting energy without visibility. No easy way to detect HVAC inefficiencies or equipment anomalies.

**Approach:** SaaS energy analytics platform on [Google Cloud](https://cloud.google.com/customers/e-on). ML-based anomaly detection and predictive maintenance for HVAC. Automated alerts: "Your HVAC runs 2 hours too long" vs. raw dashboards.

**Results and proof:**

- Launched in UK, Germany, France — 60,000+ customers
- 20,000+ meters and building management systems integrated
- €5M+ energy savings for retail and manufacturing
- 12% energy reduction in commercial buildings
- Customer proof: Tesco runs Optimum across 2,900+ UK stores, with £37M in energy savings since 2018 ([E.ON case study](https://www.eonenergy.com/business/why-eon/case-studies/tesco-energy-management.html))
