As a Senior Software Engineer and Cloud Solutions Architect with over 13 years of experience, I specialize in designing and implementing resilient, scalable, and data-intensive distributed systems. Currently at Apple, I lead teams in the Ad-delivery realm within the Ad Platforms organization where I contribute to reinvent the process of advertisement production at global scale. One of the key contributions include a config-driven & batch-based Data Enrichment System written in Scala with Apache Spark and orchestrated with Airflow, that replaced the legacy Hadoop-based system and paved the road to the next generation of Apple ad business, empowering advertisers around the world with a more responsive and reliable system.I am committed to a continuous learning of state-of-the-art System Design Best Practices and stay updated on the public Cloud providers offerings currently holding 3 AWS certifications (Solutions Architect Associate, Developer Associate & Data Analytics Specialty). I am passionate about System Design and Algorithms & Data-Structures as well as mentoring team members on such topics. The story of my life is defined by a strong passion for programming since I was 14-year-old when I learnt to write my first lines of code.
