What I do

From simple websites to ERPs, and fixes when things break.

Websites & online stores

Building, redesigning and migrating WordPress sites and WooCommerce or Shopify stores: showcase, online sales, bookings and payments, in several languages if needed. All the way to a full Joomla webshop takeover, or a project left behind by another provider.

  • WordPress
  • WooCommerce
  • Shopify
  • WPML

Custom apps & ERPs

Is your business running on WhatsApp, spreadsheets and a messy Drive? I build the tool that fits: customers, bookings, finance, commissions, documents. Web back office, API and iPhone and Android app.

  • Laravel
  • Filament
  • Next.js
  • React
  • Android

Emergency & security

Site down, hacked or hijacked in Google: diagnosis, cleanup, new credentials, hardening, then monitoring after the incident.

Maintenance

For small jobs: updates, small fixes, small changes. A 20-hour bundle paid upfront, 4 of them free, valid for one year, with no subscription. New development or a security incident is a separate project.

  • 20 h, valid 1 year
  • No subscription
  • Small jobs

Integrations & automation

Connecting your tools so nothing gets copied by hand: store and invoicing, payments and accounting, automatic reminders and follow-ups, documents generated from templates, AI to sort documents or read invoices.

  • API
  • WinBiz
  • WhatsApp
  • AI

Extra hands for agencies

Your white-label technical team: you sell and own the client relationship, I build under your brand. For a project, a busy period or a code takeover, with your tools and your deadlines.

How it works

Simple and direct. No forms, no middlemen.

  1. You write to me

    By email or WhatsApp, in a few lines: what you have, what's not working, what you want to achieve.

  2. We talk it through

    A half-hour video call to understand what you need and ask the technical questions that matter.

  3. Fixed quote, then we go

    A price agreed before we start, with no subscription and no nasty surprises. After delivery, 1 to 2 months of follow-up included: I fix bugs and check that everything works as planned.
