Custom development is affordable again. AI changes what it costs to build, integrate, and automate.
Former e-commerce founder, Shopify tech lead, 3 published apps. I like real problems and shipping working solutions.

AI changes the economics of custom development and e-commerce operations.
Tools built for your business, not the other way around
Built in days. No stacking subscriptions.
Piling SaaS tools, CSV exports, manual processes — these workarounds exist because custom development used to be too expensive. AI changed the equation: what took 3 weeks now takes 3 days. A custom tool fits your business — it doesn't weigh it down.
- Shopify themes & apps
- Headless frontends
- Internal tools
- Business applications
Your tools work in silos. So do your teams.
Sync Shopify, ERP, CRM — no more manual data entry
When data doesn't flow between your tools, your teams bridge the gap — copy-pasting, CSV imports, manual checks. I build the connectors that move your data automatically, in real time.
- Shopify ↔ ERP
- PIM / CRM
- Inventory & logistics
- Architecture & consulting
Your customers deserve better than keyword search
AI that improves the buying journey
Search that understands intent, not just words. Recommendations that adapt to context. Customer support that answers at 3 AM. AI plugs into every step of the journey — and every interaction gets smarter.
- Semantic search
- Product recommendations
- AI customer support
- Dynamic personalization
Your teams spend too much time on tasks AI can handle
Content, reporting, data processing — automated
Writing content, compiling reports, extracting data from PDFs, processing emails — your teams spend hours on repetitive tasks. AI does the same work in minutes, with fewer mistakes.
- Content generation
- Translations
- Reporting & data
- Business workflows

Jean-Baptiste Laine
Shopify Tech Lead, former e-commerce founder
I started in consulting — IS architecture at Wavestone, for enterprise clients like Banque Postale and Air France KLM. Then I co-founded La Boutique MOSO, an e-commerce brand with a store in Paris and a team of 6. Running a business end-to-end taught me what no spec ever covers.
At the LVMH digital factory, I designed and built custom headless Next.js sites — including Jardin d'Acclimatation and lvmh.com. Today, I lead the Shopify technical team at Ecocea: custom apps, themes, and integrations for brands like Polène Paris and Satisfy Running.
What drives me: understanding a real business problem and finding the most direct technical solution.
A SaaS to replace, systems to connect, a journey to rethink, an operation to automate?
