À propos de ce service
Traduction automatique
Je ne me contente pas de créer des applications web, je gère une plateforme. ConvoSync est une plateforme SaaS B2B que j'ai conçue et que je maintiens activement, permettant la gestion des messages WhatsApp et Instagram pour les entreprises. Cela signifie que je comprends les enjeux de production que la plupart des freelances négligent : gestion des erreurs, tâches en arrière-plan, limitation de débit et performance.
Ma stack : Frontend : React + TypeScript + Tailwind CSS Backend : Node.js/Fastify (ou Express) Base de données : PostgreSQL + Prisma ORM Authentification : JWT, OAuth (Google/Facebook) Déploiement : prêt pour Vercel, Railway ou votre propre VPS
Ce que j'ai réalisé :
Plateformes SaaS et tableaux de bord,
APIs REST et services backend,
Panneaux d'administration et CMS,
Intégrations tierces (paiements, APIs, webhooks)
Dites-moi ce dont vous avez besoin, et je vous donnerai une estimation honnête avant de passer commande.

This is the third time I have contacted this team, delivering exceptionally as always. They helped identify a system error causing a production issue and were open to fixing an issue not mentioned in the initial agreement. I would definitely contact them in the future.
