About

Hi, I’m Jean-François Duval, a Lead iOS Developer with 15+ years of experience and nearly 50 iOS apps shipped. I’ve earned recognition in App Store Best of 2016 and have a strong track record in Swift, UIKit, SwiftUI, scalable architecture, and SDK development. I’m passionate about building innovative applications that leverage the latest Apple technologies and cross-platform capabilities.

I enjoy leading teams, mentoring developers, and driving products from concept to launch. I embrace AI/ML, Vision, HealthKit, Siri/Intents, and multi-platform development (iOS, iPadOS, tvOS, visionOS, macOS), while collaborating closely with product and UX to ship high-quality experiences.

Kaira serves as a personal financial AI coach, helping you get more aware of your money habits, set goals, and reach them.

Not just budgeting: it includes self-assessments to figure out your relationship with money (e.g. what money means to you) and your current financial health.

You can connect your bank accounts (for certain countries) to see all your finances in one place: income, expenses, assets, debts.

It tracks your spending over time, lets you set financial goals, and gives coaching / recommendations personalized to your situation.
