Multidisciplinary Technologist — Lyon, France

I build systems that run businesses.

I find what costs you time and I build the system that fixes it. You keep the results.

I fix what slows you down.

I'm Céleste Bellier, based in Lyon, France. I help businesses cut through the noise — disconnected tools, manual routines, processes that should have been automated years ago. I identify the friction, build the fix, and hand you the keys.

My proving ground: Boutique G-Shock Lyon (Groupe Maier), where I built the entire technical infrastructure from scratch — automated shipping, KPI dashboards, order logistics, Google review management. I did the job before I automated it, and that's what makes the difference.

Everything I do comes down to one conviction: time is the only luxury you can't buy. Not speed for the sake of speed — but the belief that no one should spend their best hours on work that doesn't need a human. If I can give you back even one hour a week, I've done my job.

Your business runs on repetitive tasks. Mine eliminates them.

I build custom automations that save you hours every week — no subscriptions to bloated SaaS, no generic templates. Tailored systems that plug into your existing tools and run silently in the background.

Custom Workflow — Anything Else

If your team does the same thing more than twice a week, I can automate it. Invoice follow-ups, appointment reminders, social media posting, data entry, file management, internal notifications — name the bottleneck, I build the fix.

Your industry doesn't matter — the bottlenecks are the same everywhere. I've already solved them for others. Let's talk about yours.

Six areas, one mindset.

Every domain feeds the others. Retail informs automation priorities. Hardware thinking shapes software architecture. Trading demands real-time reliability.

Workflow Automation

I design and deploy autonomous workflows using N8N. From a single notification to a full operational pipeline — each one shaped around how your team already works, not the other way around.

Where it comes together.

I've been into tech since I was a kid — tearing apart hardware, writing my first scripts, learning how things work by breaking them. That turned into web development, then automation, operations, electronics, AI, SEO, trading tools. I don't just write code — I understand how businesses actually run, I've handled logistics, team coordination, and customer-facing operations from the inside.

I engineer in Node.js, orchestrate through N8N, fabricate by hand, and place businesses where they belong — at the top of Google. The stack is a detail. What doesn't change is the standard: every system I deliver runs itself, every site I build earns its rank, every object I assemble works on the first try. Give me the problem. I'll give you the infrastructure.
