About Baptiste

👀 Who am I?

I'm a versatile mobile engineer, building apps for 10 years. I fell into the Apple ecosystem and love exploring the (vast) possibilities of iPhone, iPad, Mac, and Apple Watch. I have shipped numerous times across all these platforms.

I have a very (very) product and user experience-oriented approach. My priority is to create value and well-crafted experiences for users.

📝 My services

My expertise isn't limited to classic development (architecture, coding, etc.). I also step in where many developers don't venture:
  • Accessibility (Dynamic Text Size, VoiceOver, Voice Control, etc.)
  • Animations & Transitions
  • Augmented Reality (AR)
  • Legacy code management (even complex and messy Objective-C code)
  • Unit Tests / UI Tests / Performance
  • Widgets
  • Live Activities
  • Swift Packages
  • ASO Strategy
  • Codebase and architecture audits

🌏 A note on my availability and remote work

I have been working 100% remotely (and often asynchronously) since 2015.
Transparent communication: every day, you know my progress, what I'm doing, and why.

📆 If you have a specific project, need help, or want to discuss your product, let me know here or book a slot directly in my calendar.

Great work from Baptiste! He perfectly managed the redesign project of our application and handled the project very well (3 iOS devs including Baptiste on architecture + interface). I highly recommend him!

We needed help improving our app's performance, developed by junior devs. Baptiste quickly analyzed the code and proposed relevant solutions to our problems. It's a pleasure to work with Baptiste, who is an experienced professional and works within our company's constraints.
