Gowazzap: WhatsApp sales assistant SaaS with human handover

Internal product of my studio, currently in launch: https://www.twine.net/signin

Brief: help small businesses answer WhatsApp sales conversations faster without losing control: qualify leads, draft replies with an AI model, and hand over to a human when confidence is low.

What I made: product design, UX/UI and full-stack development. Stack: Next.js, React, TypeScript, Tailwind CSS, Prisma, tests with Vitest and Playwright; AI replies built on the Claude API.

Status: live with a free trial. AI replies in real conditions and the official WhatsApp channel are still being validated. Role: product design, UX/UI, full-stack development.
