Independent AI Consultant
Enterprise-grade AI expertise, SMB-accessible. 15 years IT + 2 years generative AI.
ZAX is a custom software development practice founded by Eric Leroy, specializing in AI integration and modern web development. With 15+ years of IT experience and deep expertise in artificial intelligence (SKEMA Business School, ESI, MDMatch AI startup, Axis), I design and build web applications, SaaS platforms and AI-powered solutions that deliver real business value - direct relationship, no intermediaries.
Our Mission
Empowering businesses through technology that makes a difference
My mission: demystify AI and make it accessible to businesses of all sizes. Too many organizations hesitate when it comes to AI - buzzwords, exaggerated promises, opaque costs. I offer a different approach: identify concrete high-ROI use cases, deploy working solutions quickly, measure results.
AI is not an end in itself, it's a tool in service of your productivity. A chatbot that actually answers your customers' questions. Agents that automate your repetitive tasks. RAG systems that make your documentation instantly accessible. Every integration must generate measurable value.
With ZAX, you work directly with an expert who understands both the technology and business challenges. No intermediary project manager, no salesperson. A direct conversation to transform your processes through AI.
From Code to AI: My Journey
15+ years of IT experience - web agency, enterprise, freelance. I've seen projects succeed and others fail. What makes the difference? A deep understanding of business needs, not just technical skills.
My first contact with AI dates back to 2016 at MDMatch, where I developed a recommendation engine based on scikit-learn. This pioneering experience gave me a head start in understanding the generative AI revolution. Since 2023, I've been 100% dedicated to enterprise AI integration.
I created ZAX to offer an alternative to large consulting firms and AI agencies that sell buzzwords. My approach: identify high-ROI use cases, deploy quickly, measure results. You work directly with the person who codes and understands your business.
Areas of expertise
15+ years designing, coding and managing software projects with a focus on AI integration
Hybrid fullstack developer + IT project manager with deep AI expertise. I cover the full lifecycle of a software project: business framing, architecture decisions, frontend and backend development, AI integration, production deployment, ongoing maintenance. For projects that require deep specialists (dedicated UI design, heavy cloud infrastructure, offensive security), I rely on a trusted network of international partners.
This approach guarantees clients a single point of contact, fast technical decisions, and direct accountability for delivery. No opaque subcontracting, no layers of management diluting the project vision.
