Jérôme Poskin
Engineering the Future of Web.
Senior Frontend Architect & Lead Developer with over 24 years of experience. I blend the craft of code with the power of AI to create exceptional interfaces.
Human first.
AI as a force multiplier.
With over 24 years in web development — from co-founding the Snowcap agency (30 clients, 10 employees) to Lead Frontend roles for startups like Mbrella and Elium — I've learned one thing: technology only matters when it serves people.
Today, I amplify this philosophy with Artificial Intelligence. Not to replace human creativity, but to multiply it.
AI Copilot
I integrate the most advanced LLMs into my daily workflow: code generation, automated review, testing, documentation.
Accelerated Delivery
AI allows me to drastically reduce development cycles while maintaining high quality standards.
