Story arc

How this shipped

End-to-end solutions from database to deploymentThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

Collecting customer testimonials is fragmented — businesses juggle forms, emails, and manual curation. Existing solutions are expensive and lack AI-driven insights.

II · Build

The craft

Built a complete SaaS with branded collection forms, video recording, star ratings, and image uploads. AI sentiment analysis scores and categorizes feedback automatically. 10 embeddable widget layouts (grid, masonry, carousel, marquee, and more) with single-line integration. Stripe handles free through enterprise billing tiers.

III · Proof

What moved after launch

Full production SaaS with Stripe billing live at testimoniq.com. 10 widget layouts cover every design need. AI sentiment analysis turns raw testimonials into actionable insights.
