Digital transformation for SMBsin Paris and Île-de-France

I'm a **freelance consultant and independent engineer** (through my company Ouadday Digital, a French SASU registered in Paris), not an agency. In practice: I'm your single point of contact from diagnosis to delivery. No salesperson taking the brief, no project manager translating, no dev subcontracted across timezones. You talk to the person who codes, and who codes to the person who talks. That's what allows a lower budget than an equivalent Paris agency, without cutting quality. Legal status: French SASU (Ouadday Digital), VAT-exempt up to €37,500 HT (art. 293 B CGI), clean invoicing, GDPR-native. You're working with a declared independent, not a hacked-up status.

Because I do all three roles (project manager, designer, developer) in one head. You save on the budget, and gain a lot in coherence and execution speed. An agency bills three roles in parallel, with information loss at each handoff. The diagnosis, technical architecture, design and code are thought together, by the same person. No salesperson diluting, no project manager translating, no subcontracted dev.

It depends on what pays off fastest in your case, and that's exactly what the free 30-minute express audit is for. To place yourself: an audit starts at €490, a single page at €200, a showcase site at €1,490, a first automation workflow at €1,500, a custom CRM at €4,000. The final amount depends on scope, and the quote that comes out of it is firm, never a vague range.

I'm based between Paris and Kinshasa and work mostly remote. For Paris and Île-de-France clients, I travel on demand for diagnosis and training/handover phases. For clients outside IDF in France (Lyon, Bordeaux, Marseille, Lille, Strasbourg) or elsewhere (Belgium, French-speaking Switzerland, Luxembourg, Canada, francophone Africa), everything is done remotely with weekly sync points.

All my deliverables are GDPR-native: EU Vercel hosting, legal pages and privacy policy compliant with LCEN, cookie consent banner, documented processing register, EU subprocessors when possible (Brevo France, Stripe Ireland). For B2B small businesses, I also handle the minimum internal documentation (GDPR register, DPA with subprocessors).

Web stack: Next.js + React + Firebase + Stripe. Mobile React Native + Expo. Automation: your tools' native features, Make, n8n or custom code, depending on the process. AI: Claude + GPT-4 + Mistral + RAG. Data: BigQuery + Looker Studio + GA4. SEO: Ahrefs + Search Console + Schema.org + AI Overviews. The breadth comes from my primary role being architecture, not a single tool. Design stack: Illustrator + prototypes coded directly (Next.js for web, Expo Go for mobile, no Figma stage). For tools you don't use yet but could benefit from, I'll guide you without overcharging for the discovery.

Yes, generally. Not because I subcontract or cut quality, but because I remove three layers: the salesperson (you talk to me directly), project management (I'm my own project lead), and agency margin (I bill my actual time). You pay for the work, not the structure around it.

You own 100 % of the source code upon full payment. I deliver complete technical documentation: architecture, dependencies, deployment procedure, credentials, data schemas. Any Next.js or React developer can take over without continuity loss. Custom is designed to prevent lock-in, not create it.

VAT-exempt under the French small-business scheme (article 293 B of the CGI). Pre-tax invoices, payment in 30/60/10 % (upfront / delivery / handover). SEPA transfer or Stripe. Quote within 48 h. Invoices are pre-tax, no VAT collected. Standard payment in three installments: 30 % upfront, 60 % on delivery, 10 % at final handover. Contract e-signed before kickoff. No commitment before quote signature.
