I am Claudio Martins, a mobile aficionado and visionary, with over 12 years experience in the field from IT engineering, network engineering, marketing, and many different works in-between. I am a fast learner, adapt quickly to changes, work based on metrics. I consider myself a design-centric and data-informed engineer, leveraging best of both worlds with a mix of intuition. Although I've been having multiple management positions in the last few years, I am an engineer at the core and love writing code, apps and architect systems from end-to-end with extreme focus on availability, performance and user experience. I have experience developing apps for iOS, Android and backend systems (Java, Scala, etc). In the last few years I developed a passion for Analytics, tracking all user interactions, network performance, mobile network indicators, and everything that can be analyzed and transformed into actionable results. Having deep knowledge of the mobile network industry led me to create a unified view of app usage, network metrics, and backend systems, creating a real time Analytics Platform targeted to this industry using Java, Spring, Scala, ElasticSearch, MongoDB, Hadoop, Samza, Kafka, Hive and HBase. Through this I was able to give C level executives and managers real and actionable insights on how users interact with their mobile apps. With a creative mind, I am able to create simple yet useful and powerful solutions. I prefer simplicity instead of over engineering. My creative mind allows me to identify several new business opportunities and features with everything that I'm working on during meetings with customers, partners, and users. Everything converges and loops back to create a more compelling product and make users happy.
