CTO INSTAR Deutschland (Waletech R&D) Β· DevOps / DevSecOps / MLOps Β· AI & Computer Vision Plasma physics by education, bare-metal fleets by trade.
16 years from the INSTAR Deutschland GmbH QA bench to the CTO chair. Last five: building CPU-constrained AI inference chains β YOLO β ANPR β VLM β on edge hardware and a 70+ node bare-metal cloud. Still the person to call when Home Assistant stops talking to the camera.
Currently β fine-tuning CPU-loving SmolVLM for security-scene description and engineering agentic solutions - locally hosted models, MCP interfaces, testing harnesses and retrieval augmented generation. Running bare-metal, continously deployed orchestration with rock-solid monitoring and noise-free degradation notifications.
Three open repos, plus the production work behind them. Full write-ups live on the portfolio.
| Project | What it is | Stack |
|---|---|---|
| π€ Instar Camera β MCP Server Β· repo β | Turns 700+ raw MQTT camera topics into six clean, capability-level tools any LLM agent can call β set a setting, read observed state, await a change, check health, pull the latest image, list capabilities. Built on FastMCP with a reconnect state machine, observed / known-but-stale / unknown state-confidence tracking so the agent reports only what it confirmed, and credentials held in env vars β never in the prompt or logs. One open-standard integration makes the camera drivable by Claude, Codex, Hermes and the open-source harnesses. |     |
| π Instar Search Agent β Multimodal RAG Β· repo β | A Specification-Driven Agentic Engineering pipeline: a local corpus of 1,067 MDX articles (0β53 images each) normalized into a Hugging Face dataset, then embedded by a frozen open-weight Nemotron VLM into one 2,048-dim .safetensors index where text and image queries resolve against the same space. Two machine-checkable gate specs under AGENTS.md β named hard failures, REPORT_*.json, deterministic exit codes, byte-identical rebuilds β so "I use AI at work" becomes "here are the method, the code, and the proof it passes." |
  |
| π· Instar Object Detector β CPU-only Desktop CV Β· repo β | A Tauri + Rust + React desktop app that scans video, extracts the motion-event frame, then runs two ONNX YOLO models in parallel on CPU (object detection + instance segmentation through the pure-Rust tract-onnx runtime), overlaying motion regions, boxes and masks. Statically-linked FFmpeg, no Python, no GPU, no web server β a self-contained edge-inference binary with rayon parallelism. Proves I can do the whole CV path in systems code, not just Python. |

| π§ CPU-Only Cloud AI Inference Platform | One serving stack replaced a multi-GPU stack: three resident model servers (YOLOv10 / LiteRT Β· Fast-Plate-OCR Β· fine-tuned SmolVLM) behind a Redis job queue, capped Ray actor pool, load-balanced across the fleet. ~10Γ lower compute cost, accuracy held, and the memory leaks / random crashes / multi-minute stalls are gone. 10,000+ detection tasks / min in production. | MLOps Β· Distributed Systems Β· Ray Β· Redis Β· Observability Β· Nomad |
| π Edge Vision-Language Model (SmolVLM) | A VLM is a GPU-shaped tool; I had a CPU server and a hard latency budget. Fine-tuned on a security-scene dataset, primed by my YOLO detector's bounding boxes, exported to OpenVINO, served thread-safely with deterministic decoding + a 512-token budget + enforced-JSON output. | LLM Β· Multimodal Β· Fine-tuning Β· OpenVINO Β· Inference |
| π₯ Computer-Vision Engine β Edge to Cloud | Owned end-to-end: benchmarked 5 architectures, grew 3 β 19 classes from real customer complaint video, picked YOLOv7 for edge / YOLOv10 for cloud, exported PyTorch β ONNX β quantized β Novatek firmware, and closed the loop by feeding live complaints back into an MLflow pipeline until false positives and negatives dropped. | Computer Vision Β· YOLO Β· ONNX Β· Quantization Β· MLflow Β· MLOps |
| π οΈ Platform & SRE Backbone | A 70+ bare-metal / VPS fleet across 10+ datacenters on Nomad + Consul: canary-first rollouts with auto-rollback, mTLS (cfssl CA), least-privilege Sentinel ACLs, single-path GitLab CI/CD, Zabbix / Kibana observability, TLS 1.3 / HSTS ingress, backup/restore, and a fleet-wide NTS/TLS time-sync service. | Platform Engineering Β· SRE Β· DevSecOps Β· Infrastructure as Code |
| π IoT / Smart-Home Protocol Layer | Designed MQTT (MQTTv5, embedded broker + autodiscovery) and webhook interfaces in firmware β to my knowledge making INSTAR the only surveillance-camera maker exposing its full control interface over MQTT. The foundation the MCP server above now builds on; still the first escalation contact years later. | IoT Β· MQTT Β· Embedded Linux Β· API Design Β· Smart Home |
π Deep dives & written tutorials β Node-RED, OpenHAB + MQTT, GitOps, Elasticsearch search design and more on the portfolio.

My favorite clouds are greenish black Cumulonimbus. If I could get a hold of some cobra blood, I would drink it. I eat bacon, lettuce tomato sandwiches. My fuel of choice is espresso at midnight. I don't believe in moderation. I heard that money can't buy happiness and I stopped listening ever since.
I have done things for money I am ashamed of. I am fearless. I discuss pizza in a solemn, church-like whisper. I believe Smeagol was mostly a victim of bad PR and shorter measuring tapes. I think dinosaurs peaked right before the meteor. Though, I am still bitter about how they ended Lost.
My favorite holiday is Christmas, when the dread sets in. My standards are so high that I am not impressed by the Great Wall of China or NASA. The vastness of space makes me think we have to hurry up the development of warp drive technology. I believe global warming is better than cold war. And the cold war was more dramatic than anything on Netflix.
I don't believe in talent, luck or work-life balance. I know sarcasm is the lowest form of humor but I still hold it dear to my heart. I believe that every IT professional understands the necessity to improve the accessibility of the internet. I also believe most people who own a smartphone are basically using it as a very expensive flashlight.
I once was told not to give to beggars and I stopped ever since β but I am not sure how I feel about that. I don't believe in horoscopes or paintings hung above the bed. I do believei n typos. If I watch a movie that doesn't have at least one explosion, I usually have the desire to drink wine β red wine, preferably a Merlot or Cabinet Sauvignon.
I think the coolest place to wake up tomorrow would be {addLocation}. I move around a lot. I don't believe in roots.
