What I'm looking for

I’m looking for a new iOS adventure where I can modernize high-scale products, accelerate delivery with AI-assisted engineering, and mentor teams on strong architectural standards.

At Money Forward, I’m modernizing a decade-old iOS codebase for 1M+ monthly users, moving from a legacy monolith to a multi-package SwiftUI-first architecture with native async/await while maintaining 99.9% crash-free sessions.

I’ve integrated LLMs into development governance, built custom agent skills and AI-driven code reviews, and reduced production build times by 65% through CI/CD automation. I also mentor 13+ iOS developers on modern architecture and engineering standards.

Previously, I helped launch EPI’s European wallet to the Top 5 Finance apps across France, Germany, and the Netherlands, and led mobile teams at Ekonoo and Mapicts. I bring hands-on Swift, SwiftUI, UIKit, app architecture, automated delivery, and open-source contribution experience across products in finance, media, and investment.
