About this gig
Claude Code can write, test and fix code on its own. I use it every day to build the tools that run my own businesses. Now I build yours.
PROOF
390 scripts built with Claude Code for my own businesses: a 334-page website, a 30-brand design pipeline, Google Ads tools and an automatic reels subtitler.
WHAT I CAN BUILD
- Automations: connect your apps, sheets, emails and APIs
- Excel and data: clean messy spreadsheets, turn PDF tables into Excel, build reports
- AI tools: chatbots and agents using the Claude or OpenAI API
- Small web apps and landing pages
- Fixes: finish or repair an app built with Lovable, Bolt, Cursor or Replit
HOW IT WORKS
1. Tell me what you want to build or fix, and share your code if you have some.
2. I confirm the scope and the price before you order.
3. I build, test and send you the code with a simple setup guide.
WHAT YOU GET
- Clean, commented code (GitHub or zip)
- A step by step guide to run it
- Your keys and passwords stay with you: you add them yourself
Not for school assignments, hacking, or anything against a platform's rules.
Not sure it is possible? Message me first and I answer with a clear yes or no.

I'm a French entrepreneur. I founded and run a house clearance company in Normandy, and I co-founded a nail art training academy with my wife. In both, I do all the marketing myself: branding, websites, Google Ads and Instagram reels.
Pattern is the web agency where I now do the same for other businesses: logos and brand identities, reels that stop the scroll, website translation into French, and apps and automations built with Claude Code.
Clear brief, quick replies, 100% of the rights are yours. Message me your business name and what you need.

FAQ
Do I need to know how to code?
No. Tell me the result you want. I handle the code and give you a simple guide to run it.
Which languages and tools do you use?
Python, JavaScript, TypeScript, HTML and CSS, Node.js, Google Apps Script, and the Claude and OpenAI APIs.
Can you fix an app built with Lovable, Bolt or Cursor?
Yes. Share the code (GitHub or zip) and the error you see. I fix it and explain what was wrong.
Do you put it online for me?
I give you a step by step guide for Vercel, Netlify or your own server. Your passwords and keys stay with you.
Do you use AI?
Yes, openly. I work with Claude Code, then I test and review everything before delivery.
Can you turn my PDFs into Excel?
Yes, for PDFs with real text (statements, invoices, reports). Scanned paper: send one page first and I tell you if it works.
