Multimodal image-editing inference pipeline (Qwen Image Edit 2511) on NVIDIA DGX Spark

  • Ported and stabilized a Diffusers-based image editing workflow (Qwen/Qwen-Image-Edit-2511) on an NVIDIA DGX Spark / GB10 (CUDA capability 12.1 / sm_121) host, with a Mac-based JupyterLab client and a remote Ubuntu kernel execution environment.
  • Resolved GPU toolchain incompatibilities by implementing an isolated Python environment and deploying PyTorch nightly (cu130) to support sm_121, addressing NVRTC --gpu-architecture failures and CUDA capability range mismatches.
  • Identified and mitigated silent numerical failure modes (all-NaN outputs leading to black images) by systematically validating attention backends and precision; established a stable baseline using bf16 + SDPA and documented that fp16 reintroduces NaNs on the target stack.
  • Re-architected the notebook into a production-grade, reusable workflow: one-time model initialization plus a parameterized run_edit() function enabling rapid image/prompt iteration without reloading model weights, reducing OOM risk and iteration latency.
  • Implemented operational guardrails for reliability in constrained server environments: Host RAM availability checks via /proc/meminfo (MemAvailable), GPU VRAM monitoring via torch.cuda memory statistics (avoiding NVML dependency issues)
  • A ?memory gateway? executed after image load/preprocessing to proactively prevent OOM kills and Jupyter server disconnects.
  • Integrated optional LoRA adapter capability for controllable style steering (e.g., resilt aesthetic), including guidance on where/when to load LoRA (post pipeline init and encoder 
  • configuration) and operational considerations (VRAM impact, stability regression testing, PEFT dependency).
  • Produced technical documentation capturing failure analysis, parameter ladders (resolution/steps/CFG), best-practice defaults, and reproducible troubleshooting steps for remote GPU inference workflows.

In nearly all my recent projects i introduced " solutions based on OpenTelemetry (), Prometheus, Grafana, Jaeger, fluent-bit. I often introduce topics like application KPIs, metrics and then help the teams to implement respective code
  • As a Senior/Lead System Architect for companies like Telekom, Siemens ITS, Siemens Mobility, Allianz, Arvato, Lufthansa Industry or BSH, I successfully achieved my tasks analyzing complex systems, identifying both explicit and implicit requirements, and delivering solutions that align with all stakeholders' expectations. My role has often involved acting as a senior technical liaison for both local and offshore development teams, notably establishing successful collaborations with teams in India - including on-site visits in India
  • My expertise extends to UX/UI design, where I have developed a focus since my time as UI Specialist at Vodafone Global. I offer services from analysis and integration of standards to wireframe creation and briefing visual designers. In addition i implement UI using Angular and Ionic or Vue with Wails for example. My services include designing interfaces for embedded/edge systems, mobile solutions, and multimodal UIs, with a particular emphasis on integrating speech dialog systems and developing NLP and LLM-related solutions for edge devices.
  • In the realm of big data and data space systems, I am experienced in building scalable architectures using Kafka, NATS, TimescaleDB, Presto, Pig, S3 and Hive. Another focus includes exploring Iceberg for structured big data management. My primary goal is to help customers identify and implement optimal solutions by thoroughly understanding their requirements and acting as a strategic sparring partner to refine and enhance project scopes. I work with on-premise hardware, cloud systems (AWS, Azure, GCP) and various custom IoT devices ? a dedicated hardware lab is part of my environment
  • I also consider workshops and technical consulting for companies and teams for topics like LLMs, GenAI, Backends-System Architecture etc. These are usually short-term projects and are not listed in my history
