I am an
AI Engineer

I build the pipelines behind the pictures. Generative AI, ComfyUI workflows, model optimization and AI/CGI hybrid production — for agencies, platforms and artists who want work that ships, not just demos.

The engineer behind the image.

Dennis Schöneberg

Depth Anything V2 and DWPose, run on this portrait. The depth pass is what drives the parallax.

I work part-time as an AI Production Engineer at Grabarz & Partner — an award-winning Hamburg agency that became part of the Omnicom Group in July 2023 — bringing generative AI into real creative advertising production.

In parallel, I freelance as an AI Engineer, Consultant, Author and Artist for startups and studios worldwide: building ComfyUI pipelines, training LoRAs, optimizing models and directing AI/CGI hybrid productions.

I believe cutting-edge AI unlocks new possibilities for creative processes — my job is to turn that belief into workflows that are fast, consistent and production-grade.

FIESP Cultural Center, São Paulo, Brazil

Four AI music videos — created with SD 1.5 and Deforum — exhibited in the QUBIT AI show at FILE, the Electronic Language International Festival.

The synthesiser doubles as the camera rig. Musical parameters are wired straight into the generation, driving the camera through the 3D space, the weighting of the prompt, and how much freedom the model is given. Sound and image are not cut to each other — they run off the same signal.

“Cutting-edge AI unlocks new possibilities for creative processes — my job is to turn them into production-grade workflows.

The tool behind the hybrid work: a standalone editor around my ComfyUI inpainting node, so a retouch does not have to happen in a node graph.

Scumble.

Own work2026
0.1.x · free download

Scumble

A desktop editor for AI inpainting.

Open an image, select an area, write a prompt, generate. The result lands as a layer over the selection and stays editable: colour-matched to its surroundings, masked, erased in parts, regenerated, stacked with filter and text layers, exported with all layers to PSD or OpenRaster.

Scumble with a picture open: the tool column on the left, the canvas, the layer stack and the selection panel on the right
The round trip
  1. 01SelectBrush, rectangle, lasso, magic wand, a click on an object (SAM2 in the app) or a sentence — "the handbag" — for a text selection.
  2. 02GenerateA recipe instead of a node graph: pick the model and where it runs — your own ComfyUI, local or on RunPod, or an API provider with your key.
  3. 03MatchOne slider per layer blends the result into the picture: colour match against the surroundings or against what lies below.
  4. 04LayerFilter layers on the GPU, a film pack, text, 3D objects, custom brushes. Nothing is baked in until you flatten.

Every step is a command, so an agent can do the same round trip.

Windows today, Linux and macOS planned. A tile engine with Rust kernels keeps 15,000-pixel documents usable; PNGs up to a gigapixel open and save in strips.

Select, prompt, generate

The same result layer at colour match 0 % with a visible cold rectangle and at 100 % blended into the ground, below it the layer row with the Match slider

The layer stack: a vignette and a film look as filter layers, a text layer and the base image

The assistant panel: the request, the model's reply, two finished tool cards and a generate call waiting for Allow or Don't

The assistant asks before it renders

Agents and the assistant

The editor exposes 60+ commands over MCP, so Claude Code, Claude Desktop or any MCP client can drive it. The same commands feed the built-in assistant: a chat column next to the canvas that runs on your own key — Anthropic, OpenAI, Google or any OpenAI-compatible endpoint — operates the editor itself, shows every call as a card, and asks before anything costs money. Every step is undoable, and a whole turn can be taken back at once.

The API adapters and the assistant are written from the providers' documentation and are not yet tested against the live services; local rendering through ComfyUI is.
