Freelancer profile translated to English.
Back to original languageAbout Dany
Hello, my name is Dany, a computer engineer and entrepreneur. For several years, I have been designing, developing, and operating my own SaaS products end-to-end – which has allowed me to develop skills across the entire product lifecycle: from code to production, including payments, legal compliance, ASO, and customer relations.
Main technical stack:
Mobile: React Native / Expo, iOS + Android deployment, EAS Update (OTA)
Web: Next.js (App Router), React, TypeScript
Backend & Data: Supabase (PostgreSQL, Auth, RLS, Edge Functions, pg_cron)
Payments: Stripe, Stripe Connect (Standard), Stripe Billing, RevenueCat
Tools: Sentry, EAS, Posthog, GitHub
My products:
- Milky Lady (milkylady.fr) — B2C mobile app for managing breastfeeding and infant feeding. Full product design, Premium subscription, AI scan, customizable diversification journal.
- Playciz (playciz.fr) — B2B2C SaaS for managing tennis and padel clubs. Stripe Connect, POS integration (Hiboutik), Next.js + Supabase blog.
- PiloteReady (piloteready.fr) — Web platform for preparing for military pilot entrance exams.
What I can do as a freelancer:
- Development of React Native / Expo mobile applications (from scratch or evolving an existing product)
- Next.js + Supabase web development
- Integration of complex payments (Stripe Connect marketplaces, Stripe, RevenueCat)
- Supabase backend architecture (RLS, Edge Functions, cron jobs)
I bring a dual perspective as an engineer and an entrepreneur: I understand technical constraints, but also time-to-market, profitability, and the business stakes behind every decision.
