LomiTips
Data-driven football tips. A football prediction platform powered by live data from the top-five European leagues, with a public web tier and a creator-admin dashboard.
What we built for LomiTips.
LomiTips ingests fixtures, lineups, and form from football-data.org, runs a typed prediction engine, and publishes tips through a Next.js 15 web app and an Expo mobile app. Admins curate matchday content from a privileged dashboard, while end-users get a clean public feed.
The problem
Most prediction sites are cluttered, ad-laden, and serve stale data. The team wanted a calm, data-first product where every recommendation links back to a verifiable signal — and where mobile and web stay in lockstep.
Our solution
A pnpm monorepo with shared types and a thin API client. Web on Next.js 15, mobile on Expo SDK 52, both backed by the same Postgres + Prisma schema. Auth via better-auth (cookies on web, bearer on mobile), and a scheduled fetcher refreshes leagues without manual ops.
What ships with LomiTips.
Every feature is engineered to be observable, type-safe, and measurable in production.
Top-5 leagues
Premier League, La Liga, Serie A, Bundesliga, Ligue 1 — fixtures, form, and head-to-head signals.
Typed everywhere
A single shared package types the API surface for both web and mobile, so contracts never drift.
Admin curation
Editors can override predictions, attach reasoning, and schedule publication windows.
Mobile parity
Expo router with React Query keeps the mobile app feature-equal to the web on day one.
Tracked accuracy
Every published tip is auto-graded post-match so accuracy stats are public and honest.
Performance budget
Edge-cached pages with sub-100ms TTFB on the marketing surface, reactive data on detail pages.
