Back to original languageAbout Víctor
Lead mobile engineer with 13 years of experience leading teams and Android/multiplatform architectures. I help companies migrate to Kotlin Multiplatform, build apps from scratch, or professionalize the architecture and practices of their existing mobile teams.
With over 13 years as a software engineer specializing in mobile applications, I help companies and teams to:
- Define and lead mobile architectures, whether native (Android/Kotlin) or multiplatform (Kotlin Multiplatform + Compose Multiplatform).
- Migrate existing projects to modern stacks (Compose, KMP, MVVM/MVI) without slowing down delivery speed.
- Build apps from scratch with best practices from the first commit: testing, CI/CD, scalable architecture.
- Train and mentor teams in Kotlin, modern Android, and development practices.
- Integrate AI into the development process and the product itself (I have led the development of an AI agent as a product feature).
Some projects I have worked on include payment apps (Waylet, used in all Repsol gas stations), last-mile logistics apps (Citibox), and commerce marketplaces (Klikin), among others, for companies such as Iberia, Eventbrite, Repsol, and Citibox.
Available for technical consulting, temporary team leadership (interim CTO/lead), architecture audits, or direct development on Kotlin/Android/KMP projects.
