Workflow automation, operations management, embedded electronics, trading tools, and full-stack web — I build the systems that let businesses, institutions, and teams focus on what actually matters.
I'm Céleste Bellier, based in Lyon, France. I help businesses eliminate everything that wastes their time — manual tasks, broken processes, tools that don't talk to each other. I build tailored systems that run on their own, so teams can focus on what actually matters.
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.
Beyond automation, I develop in Node.js, fabricate electronic objects by hand, and build websites that earn their place on Google. Every domain feeds the others.
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.
Full analysis of your Google Business profile, your website performance, and your local SEO. Monthly automated reports with actionable insights — foot traffic, search queries, competitor benchmarks — delivered straight to your inbox.
Every new review triggers an instant AI analysis — sentiment, key topics, urgency. Good reviews get a personalized thank-you response. Negative ones get flagged with suggested action. Weekly digest with trends and rating evolution.
Stop wasting hours on spreadsheets. I build automated dashboards that pull your data from any source — POS, e-commerce, Google Analytics, CRM — and deliver clean weekly or monthly reports to your team. No manual work, ever.
Every form submission on your site gets analyzed by AI in real time. Spam gets filtered, legitimate inquiries get profiled — who they are, what company, what they want. You receive a rich brief, not a raw email. Response time: instant.
From order confirmation to label printing to delivery tracking — the entire chain automated. Works with DHL, UPS, Colissimo. Customer gets notified at every step. Your team just packs the box.
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.
Whether you manage a restaurant, a boutique, a clinic, an agency, or a warehouse — the processes eating your time are the same ones I've already automated for others. Let's talk about yours.
Every domain feeds the others. Retail informs automation priorities. Hardware thinking shapes software architecture. Trading demands real-time reliability.
End-to-end business process automation using N8N — orders, invoicing, client follow-ups, reporting, notifications, data sync. Any repetitive task your team wastes time on, I turn into a self-running workflow.
Hands-on experience managing day-to-day operations — team coordination, customer experience, inventory, sales strategy, and performance reporting. Whether it's a boutique, a restaurant, or an office, I understand how a business runs from the inside.
Deep-dive technical solutions tailored to specific industries. Proven track record in luxury retail (Casio/G-Shock ecosystem) — e-commerce auditing, catalog quality, AI assistants. The same methodology applies to any sector.
Designing and building physical electronic objects — ESP32 robots, custom PCB integrations, thermal printer setups, IoT prototypes. From firmware to physical assembly.
Full-stack applications from concept to deployment. Node.js backends, expressive frontends, private client portfolios, Nginx proxy management, AI-powered tools. Every site ships with proper SEO.
Automated crypto analysis pipelines — real-time Telegram alerts, multi-horizon forecasting, portfolio tracking, and performance dashboards for informed decision-making.
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. When I automate a process, it's because I've done it manually first.
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.
Automation, web apps, operations tools, hardware, or something I haven't thought of yet.
