About Tony

Next.js Developer | Fullstack JavaScript/TypeScript | AI-Driven Dev

I build performantNext.jsandReact.jssolutions that turn your ideas into **scalable products**.



**Fullstack Developer with +8 years of experience**, including over 3 years in AI integration (long before it was trendy). I design **custom web applications, SaaS**, and systems driven by **AI agents**.


My method: **AI-driven development**, scoping → implementation → review → delivery.

I contacted Tony for an initial mission on the Skipcall project, and frankly, it was a great experience that led to ongoing collaboration. He is autonomous and managed a task from A to Z without me needing to follow up. He's also rigorous; everything is delivered clean and on time. He adapted well to the small team and the pace. A very good communicator too; we always know where things stand, no gray areas. And what really makes a difference is that he doesn't hesitate to challenge ideas that don't hold up. This pushes the project forward. I recommend him without hesitation.
