Selected work

My broadcast work for TV Markíza is confidential, so everything here was made new for this portfolio: original, rendered locally and documented from the first idea to the final frame.

One Character, Twenty Worlds

One original character placed in twenty different scenes, with a face-similarity score for every frame. Most AI artists claim consistency. This piece measures it.

Output20 stills and a drift report
ResultAll 20 scenes above the same-person line

Drift reportMean 0.69 · lowest 0.45

Face similarity to the reference, scored with OpenCV SFace. 0.36 is its same-person line.

Thirty Seconds

A 30-second spot for a fictional product, made end to end: idea, script, storyboard, generated shots, edit, original music and sound design.

ComfyUI nodes and apps

I build the nodes a pipeline needs, up to whole apps inside ComfyUI. Studio is one: create, edit, a gallery and a model manager in one window, with the workflows running underneath.

Built withPython, ComfyUI server API, JavaScript

AIOS

The AI operating system I run my work and life on. Specialist routes do the work, research subagents gather evidence, and every correction becomes a rule the agents follow next time.

Final Wish

An independent sci-fi short film I wrote, directed and shot.

I work where broadcast production meets agentic software. At TV Markíza I generate AI video and build the tooling that makes the pipeline repeatable. Outside work I design agent harnesses, including an AI operating system that runs my research, engineering and production and learns from every correction.

ExperienceTen years of making things people watch, the last three with AI at the centre.

One face. Every frame. Scored.

I build ComfyUI pipelines that keep an AI character on-model across outfits, poses, lighting and scenes, for creators, agencies and brands. Every delivery includes a drift report: twelve fixed test prompts, each with a pass, drifting or rebuild verdict, so weak spots are fixed before final delivery.

  1. Character testA drift report on your character concept and 10 on-model images.2 days
  2. Character pipelineA ComfyUI workflow tuned to your character, a trained LoRA when it needs one, 40 images and the drift report.4 days
  3. Content engineThe pipeline plus batch generation from a spreadsheet, image-to-video and setup on your GPU or cloud.7 days

Price by agreement. Pipelines come with the workflow files, the settings and a guide, with full usage rights for your project.
