Services · SMS verification platform development

Run a virtual number and SMS verification service

I build SMS verification platforms: supplier integrations, prepaid wallets, automatic refunds, fraud controls, rentals and a reseller API.

Who it's for

Operators and resellers launching a virtual-number or SMS-activation service.

An SMS verification service lives or dies on reliability and money handling: codes that arrive, refunds that happen exactly once, and payments that can’t be faked. I build platforms where those parts are designed and tested first.

What I build

  • Number purchase by service, country and operator, with live SMS polling
  • A prepaid wallet with atomic debits and automatic refunds
  • Supplier integrations with routing by delivery rate, price and stock
  • Card and crypto top-ups with verified webhooks and fraud controls
  • Monthly rentals, shared numbers and email forwarding
  • A reseller REST API with OpenAPI docs, and multilingual SEO pages

How I work

  1. 01

    Discovery

    A call and a short written scope: what we're building, what success looks like, and what's out.

  2. 02

    Build in weekly steps

    You see working software every week on a preview link, not a big reveal at the end.

  3. 03

    Launch and hosting

    I deploy to your servers or a VPS with monitoring, backups and HTTPS.

  4. 04

    Support

    I stay on to fix, measure and improve — the same developer who built it.

Questions

Which SMS suppliers can you integrate?

Any supplier with an API. I've integrated several, with health checks that switch a failing supplier off automatically and routing that prefers the best delivery rate.

How do you prevent wallet and refund bugs?

Debits and refunds are atomic database operations, each claimed exactly once, with tests that fire parallel purchases at the same wallet.

Can you handle payment fraud?

Yes: 3-D Secure checks, card holds, shared-IP rules, chargeback tracking and ID verification, tuned to keep good customers flowing.

Can it rank in several languages?

Yes. The platform I lead serves 24 languages with translated URLs and pre-rendered pages for every service and country.

Have a product to build or fix?

Tell me what you're working on. I'll reply with questions or a first plan.
