Informazioni su questo servizio

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.

    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.
