Over deze dienst
I don't just build web apps, I run one. ConvoSync is a B2B SaaS platform I built and actively maintain, handling WhatsApp + Instagram messaging for businesses. That means I understand production concerns that most freelancers skip: error handling, background jobs, rate limiting, and performance.
My stack: Frontend: React + TypeScript + Tailwind CSS Backend: Node.js/Fastify (or Express) Database: PostgreSQL + Prisma ORM Auth: JWT, OAuth (Google/Facebook) Deployment: ready for Vercel, Railway, or your own VPS
What I built:
SaaS platforms and dashboards,
REST APIs and backend services,
Admin panels and CMS,
Third-party integrations (payments, APIs, webhooks)
Tell me what you need, and I'll scope it honestly before you order.
