univis · vision saas

context

Univis is an AI vision-board SaaS. Users bring reference images and structured prompts; the product returns photoreal results that feel coherent rather than generated.

what i built

Full architecture: authentication, Cloudflare R2 storage, Dodo Payments, user dashboards, and the multimodal generation pipeline running on Gemini Nano Banana.

A 780-line prompt system that turned vague vision-board ideas into structured, repeatable generation inputs.

engineering choices

Cloudflare R2 over standard cloud storage to keep egress costs in line with the business model. The prompt system was treated as a first-class artifact, versioned and tested rather than scattered through the codebase.

outcome

End-to-end SaaS surface in production. The prompt system is the part I am proudest of; it carries most of the perceived quality of the output.
