Description

⚡ TECHNICAL LEADERSHIP, DEVELOPMENT AND TRAINING

With over 14 years of experience, I have led mobile development teams and projects, and designed custom training programs for companies such as Inditex, Banco Santander, BBVA, Telefónica, Bankinter, Adif, Mutua Madrileña, Ilunion, KnowmadMood, Public Administrations, and multiple startups.

🚀 MOBILE TECH LEAD

I bring a strategic and technical vision, coordinating multidisciplinary teams and ensuring quality and deadlines at each project phase. I get involved from planning to maintenance, technically guiding the team and facilitating fluid communication between design, product, and development.

🤖 ANDROID AND KOTLIN MULTIPLATFORM (KMP) EXPERT

With solid experience in Kotlin and Java, I work with technologies like Flow, Coroutines, Ktor, Room, Koin, and NavGraph, under modern architectures (MVVM, UseCases, Repositories). I develop cross-platform solutions with KMP, optimizing shared code without sacrificing native experience on Android and iOS.

🍏 IOS DEVELOPMENT WITH SWIFTUI

I have developed and led iOS projects in Swift, SwiftUI, and Objective-C, using various architectures. I master new APIs like Swift Concurrency (Async/Await) and integrate unit tests to ensure maintainability, performance, and scalability.

🎓 TRAINING AND MENTORING

I provide specialized training in mobile development (Android & iOS), adapted to the profiles and objectives of each company, from basic courses to advanced bootcamps. I also support junior and mid-level developers in their growth within the team.

🎯 VISION, COLLABORATION, AND RESULTS

I am passionate about taking on challenges and delivering real value. I enjoy leading technical initiatives, improving processes, and creating collaborative environments where each member can grow. My focus: building strong teams, paying attention to details, and achieving excellent products.
