Back to original languageAbout Antoine
Independent developer for almost 15 years, I have built software with a consistent guiding principle: eliminate repetitive tasks through technology. Expense reporting SaaS, AI-powered form recognition, invoicing automation, in-store music broadcasting — each project shared the same DNA.
When AI exploded, I was among the first impacted — on the code side, daily. Instead of resisting, I dove in. I spend my evenings testing what comes out so my clients don't have to.
For freelancers, VSEs, and SMEs:
Discovery call (30 min, free) → Immersion day at your premises (€590): I observe, participate in your daily work, and you receive an actionable report within 48 hours with concrete AI opportunities for your business → Implementation by quote: custom prompts, automations, team training. If AI can't help you, I'll tell you honestly.
For development teams:
Discovery call (free) → Audit per team (€590/day): stack, CI/CD, workflows, current adoption level → Implementation: coding assistants configured for your stack, automated code checks, dev/PO/QA training → Monthly follow-up to filter what truly matters for your context.
What sets me apart:
— I only recommend what I use myself.
— 10+ years of SaaS delivered to production: not a theoretical consultant, someone who knows how to code and deploy.
— Not a PowerPoint: things that run in production.
First contact: 30 min video call, 100% free, and no obligation.

Experience
- EnsilogFreelance Software Developer & ArchitectDIGITAL AND ITDecember 2013 - Today (12 years and 8 months)Mâcon, FranceEnsilog is the freelance structure I founded to support my clients in the design and development of custom software solutions.10 years of experience:I have worked on a wide variety of projects — web, desktop, and mobile applications — in monolithic and microservices architectures, with various stacks (.NET, Angular, Elasticsearch, PostgreSQL, MongoDB). I have both developed and provided technical coordination, in local teams as well as nearshore (including assignments at Accenture).But most importantly, I built my own products from A to Z, alone: code, architecture, marketing, SEO, client relations. This SaaS maker experience forced me to master the entire chain — not just the code.The AI turning point:When generative AI exploded, I was impacted before anyone else — in my own profession. Instead of resisting, I explored everything: LLMs, intelligent agents, assisted development tools, business process automation.Today, Ensilog is evolving towards AI consulting. My role: to help freelancers, VSEs, SMEs, and dev teams concretely identify where AI can save them time — and implement it. No theory, no PowerPoint: custom prompts, automated workflows, trained teams.What 10 years of development have taught me is that the best technology is the one that disappears in use. AI is no exception to this rule.
