Cumpri

§ 1The starting point

Cumpri brings small groups together around a shared challenge with a deadline. The product connects a public landing page to a mobile-first web app for organizing challenges and following progress.

§ 2The problem to solve

Starting a goal is different from keeping it going. Groups need a shared place to define the challenge, record daily progress and see who is participating, without losing those updates in a chat.

§ 3What I built

The experience centers on challenges, invitations by link and daily check-ins with text or photos. Streaks, points and rankings make progress visible to the group. The monorepo separates an Astro landing page, a React PWA and a Fastify API with Drizzle and PostgreSQL.

§ 4Where it stands

The project brings product communication, the participant experience and the backend into one codebase. The landing page presents the proposal for different uses, including studying, fitness, music and creative work.
