DietCoach is my own SaaS product: a platform where personal trainers manage their clients' diet plans.
Trainers add clients, generate meal plans and export them as clean, paginated PDFs with full recipes, ingredients and portions. Every recipe in the database is available in Polish and English.
What I built:
• The full app: Next.js App Router, strict TypeScript, Supabase (auth, Postgres, row-level security)
• Plan generation, client check-ins and adherence alerts on the dashboard
• Subscriptions, onboarding checklist and an in-app help section
• A custom dark interface ("Engine Room"): glass cards and inner glow, tuned to stay smooth in Safari
• Legal layer for an EU product: consents, data processing agreement and account deletion
