I build production-grade AI image and video pipelines with ComfyUI and RunPod serverless — the kind that actually work at scale instead of breaking the moment you take them off your laptop.
I'm the founder of Apatero (apatero . com), an AI content generation platform running on a Django + RunPod + ComfyUI stack handling image, video, audio, and 3D generation in production. I built it from zero and ship to it daily, so I know what breaks at scale and how to design around it.
What I deliver:
- Custom ComfyUI workflows for image and video generation (FLUX, SDXL, WAN, LTX, Hunyuan, and more)
- RunPod serverless deployment — turning ComfyUI workflows into cost-efficient APIs your app can actually call
- Character consistency pipelines — FLUX LoRA training (diffusion-pipe, ai-toolkit), PuLID / InfiniteYou face locking, ControlNet for pose and scene
- Virtual try-on (VTON) and product photography automation
- AI influencer and character generation with full identity consistency across images and video
- Backend integration — Django / FastAPI, Celery queueing, Redis scaling — all the infra that makes generation pipelines production-ready
- Documentation and screen-recorded walkthroughs so your team can take over after delivery
Recent work:
- Delivered a virtual try-on (VTON) ComfyUI pipeline for a luxury fashion client
- Ship character-consistent storybook illustration at scale (Flux Dev + custom LoRAs)
- Operate Apatero, a production AI platform on RunPod handling image / video / audio / 3D generation
Who I work best with:
- Founders building AI products who need infra that actually ships
- Teams with an existing ComfyUI workflow that needs to become a production API
- Clients who want to learn the workflow through screen-share consulting, not just receive a black box
Not a fit if:
- You need unlicensed celebrity likeness, deepfakes, or identity impersonation work
- Your budget is sub-$30/hr — I'm not the cheapest, I'm the one whose pipelines don't break in production
Open to ongoing engagements and fixed-scope projects with clear milestones.

I'm a full-stack developer with a background in product and design. I don't just write code to spec, I think about what should get built, how users will experience it, and what to prioritize. I've worked with early-stage startups where that kind of thinking matters as much as the technical execution.
On the technical side, I build and ship production systems across the full stack. Backend architecture, database design, cloud infrastructure, and frontend. I've worked hands-on with RAG pipelines, vector storage, and LLM integrations in production.
Stack: React, Next.js, Vue.js, Laravel, PHP, Python, Node.js, Supabase, PostgreSQL, MySQL, AWS, Docker, Stripe
Notable projects:
- AI-powered SaaS platform with RAG pipeline and namespaced vector storage for structured team workflows
- Document automation system for law firms using RAG-based retrieval across legal documents to streamline case preparation and internal processes
- AI-driven school platform in Germany with automated quiz generation and personalized student feedback using LLM integration
- Kosovo's first API-driven news aggregator processing real-time data from multiple sources
- Service outage monitor with live heatmap visualization covering national infrastructure
