The problem

Interior teams need to move from plans and references to client-ready options quickly, but AI rendering products often hide provider cost, moderation failure, asset provenance, and the point where a human must approve the result.

The challenge

I shaped the product around one supervised journey: upload a plan, confirm walls, rooms, and scale, place furniture and finishes, approve each room, then render and assemble a presentation board. Every paid action reserves credits before work starts and settles or refunds them when the job ends. Uploads are scanned and quarantined before anything reads them, and a final render cannot start until a person has approved the room. GPU work sleeps when idle and carries a hard time budget, so a stuck job cannot keep burning compute.

System Design

RenderBoard runs on Azure Container Apps: a Next.js web app, a FastAPI API with a malware-scanning sidecar, a plan-reading service, and Celery workers on Redis. GPU workers for path-traced rendering, upscaling, and segmentation scale to zero and wake from the queue. PostgreSQL enforces row-level security for the API, and files live in blob storage behind managed identity.

Results

RenderBoard is deployed end to end as an internal test release. A synthetic production journey has taken a plan from upload through room approval to a 4K path-traced render, and diffusion rendering, select-and-repaint, and upscaling are verified in the live environment. Payments stay off, and the public launch waits on the gates in the release register.
