About Me
I am an experienced Engineering Manager and Mobile Tech Lead with a strong background in mobile development, team leadership, and product management. Over the years, I have built and managed multidisciplinary teams, improving their performance significantly while leading projects that span technology, marketing, and content domains. My approach is data-driven, utilizing user behavior analytics and A/B testing to optimize retention, reduce churn, and increase conversions.
My technical expertise includes mobile platforms, particularly iOS and Android, with proficiency in Swift, Kotlin, Objective-C, and cross-platform frameworks like Flutter and React Native. I have successfully migrated legacy platforms to modern technologies and implemented gamification features to enhance user engagement. I am also experienced in building personalized feeds and improving app performance through memory optimization and crash reduction.
In addition to my engineering skills, I have held leadership roles such as CIO and Product Manager, where I orchestrated projects for various clients, implemented hiring processes, and established sales departments. I am comfortable handling financial analysis, tax reports, budgeting, contracts, and legal frameworks.
I am passionate about continuous learning and have earned certifications in Azure Fundamentals, AWS Cloud Practitioner, Databricks Lakehouse, and Google Adwords. My language skills include native Spanish, proficient English, and conversational Portuguese. Outside of work, I have interests in psychology, gastronomy, and travel.
I am motivated by challenges and enjoy working in dynamic environments where I can contribute to both technical excellence and business growth. I am eager to bring my skills and experience to new opportunities where I can lead teams and deliver impactful products.
