Who I work with

What already works for other businesses, adapted to yours

I don't sell generic software. I take pieces already in production and fit them to how your team works.

Law firms

WhatsApp enquiries at all hours, paper engagement letters, retainers you have to chase and Veri*Factu around the corner.

  • A WhatsApp assistant that separates new enquiries, existing clients and urgent matters.
  • Engagement letter signed by the client on a tablet, with a copy by email.
  • Upfront payment for the first consultation or the retainer, Bizum included.
  • Veri*Factu-ready invoicing without changing how you work.

Real estate agencies

Foreign buyers messaging in the middle of the night, portal leads going cold and shared commissions reconciled by hand at month end.

  • A WhatsApp assistant in the buyer's language that only answers with your listings.
  • Each prospect's profile ready in the morning: budget, area and timing.
  • Commissions with partners and other agencies calculated automatically.
  • Online reservation deposits and several offices in one dashboard.

Software companies

Need a senior profile who joins your team and delivers from week one? I've spent years building multi-app platforms with payments and integrations in production.

  • Nuxt & Vue 3
  • TypeScript
  • Firebase & GCP
  • Multi-tenant
  • Payments & integrations
  • WhatsApp & AI
  • Veri*Factu

Questions

What people usually ask

If it's not here, write to me.

  • It depends on scope, but always a fixed price in writing before we start. The initial assessment is free and commits you to nothing.

Shall we talk about your case?

45 minutes, no strings attached. Tell me how you work today and I'll tell you honestly whether and how I can help.
