Hello, I understand you’re building a complex full-stack SaaS platform with multi-tenant architecture, payments, media processing, and GPU/ComfyUI workflows. I have experience with TypeScript (Node, React, Express, Postgres) building SaaS systems with auth (OAuth/JWT), multi-tenant isolation, and secure role-based access control. I’ve also implemented Stripe billing with subscriptions, webhooks, and usage-based metering systems. On the infrastructure side, I’ve worked on media-heavy systems using S3/R2 storage, CDN delivery, signed URLs, and FFmpeg pipelines for transcoding, thumbnails, and HLS workflows. I’m also familiar with async job queues that scale into GPU-style workloads using external services like RunPod or Replicate. Frontend experience includes React, Tailwind, and shadcn/ui to build clean product interfaces and embedded/widget-style components. I also understand ComfyUI-style systems — node-based workflows, JSON editing by node ID, and backend orchestration for running those pipelines. Overall, this is a full ecosystem involving: • Multi-tenant SaaS architecture • Payments and usage metering • Media processing pipelines • GPU execution layer • Scalable backend + DevOps I’m comfortable working in early-stage systems where architecture decisions are critical and scalability needs to be designed from the start. I’d be happy to jump on a quick call to understand your MVP scope and help design a clean, scalable foundation for the platform.

You need someone who can own the multi tenant stack, payments for the adult ecosystem, and ComfyUI plus GPU ops end to end. The real risk is getting tenant isolation, usage metering and ML costs aligned with compliance and reliable webhooks. On ProgramPro I built an AI SaaS backend with Postgres, Stripe integrations, realtime model orchestration and production deployments so I understand the full stack plus model ops trade offs. I will audit the repo and schema and propose a SQLite to Postgres migration with row level access controls and Drizzle friendly schemas. I will design GPU queueing, autoscaling and cold start strategies using RunPod or a Kubernetes alternative with retry and backoff. I will wire ComfyUI node management, model file handling, signed media URLs, FFmpeg video pipeline hooks, and subscription metering with adult friendly payment webhooks. Can you grant repo access or share the current architecture diagram so I can draft a focused two week plan and estimate?

✋ Hi - I'm Larry from Atlanta. My approach would be to separate the product into clear layers: tenant-safe web app, payments and credit metering, GPU job queue, ComfyUI workflow service, media processing pipeline, storage/CDN layer, and trust/safety review tools. For adult content, I would keep the system consent-first, age-gated, auditable, and built around strict moderation workflows. I built multi-tenant media SaaS system with role-based access, usage credits, file processing, background queues, signed media URLs, and admin moderation. The key was preventing tenant data leakage while keeping high-cost background processing controlled through metering, retries, and clear job states. For ComfyUI and GPU ops, I would manage workflow JSON by node ID, model files, custom nodes, queue status, cold-start recovery, retry/backoff, and worker scaling. For video, I would use FFmpeg for trim, transcode, thumbnails, watermarking, and HLS delivery where needed. Let's discuss more through chatting. I can start immediately. Thank you, Larry

Hi! I can help you with this full-stack build. The combo of ML infra, ComfyUI workflows, and multi-tenant SaaS with adult-friendly payment processors is a meaty project but I've worked across most of this stack. GPU queueing with autoscaling and cold-start handling, Stripe webhook integrations, S3 signed URLs for media delivery, and FFmpeg pipelines are all things I've built before. I'm Edward, 10+ years as a senior dev. I'm comfortable with the Python side too for ComfyUI custom nodes and FastAPI services. Let me know if you want to discuss the architecture approach.
