About Roberto

Many AI solutions work well in demos but fail in production due to integration issues.

I help teams bring AI to real iOS applications, building robust, well-integrated features with measurable product impact.

As a Staff iOS Engineer, I design and implement AI-based systems that replace complex workflows and improve user experience, always focusing on reliability, scalability, and real-world usage.

I've been fortunate to work on iOS apps that people actually use, some with a global reach of millions of users. I'm motivated by helping real users, writing simple code, and making things work better.

I am an iOS Developer with over 12 years of experience, primarily in Swift and SwiftUI, building high-quality, scalable, and user-centric products.

Throughout my career, I've collaborated on international products with huge audiences, focusing on performance, reliability, and UX. I enjoy being close to the product, understanding user needs, and finding direct solutions to complex problems.

In recent years, I've worked on product within MEGA, an app with millions of users, where I've reinforced my focus on architecture, quality, and user-oriented decision-making. I am now returning to the freelance market eager to apply all I've learned in real-world environments.

I am particularly interested in working on:

📱 Native iOS Development (Swift, SwiftUI)
🧠 Integrating AI into products (not just demos)
🧪 Clean Architecture, Testing, and Maintainability
🚀 Apps that need to scale and evolve

I have worked in internationally distributed teams, collaborating closely with design, backend, and product. Clear communication and well-founded decisions are key for me.

If you are building something impactful and looking for someone who cares about the product, quality, and users, let's talk.
