As a senior iOS developer, I have accomplished the following: - Implemented iOS and macOS apps for soil study and automated messaging using native development tools. These apps make air and soil temperature predictions based on satellite imagery, which helps farmers take preventive actions on their crops. -Planned and developed mobile apps for a global financial services corporation; implementations in Colombia and Mexico have 1+ million users and helped to generate 40.4 % net revenue. - Ensured understanding and implementation of Scrum inside and outside development teams for an international multilevel marketing company with 3.300+ workers around the globe. - Performed data migration of 180+ million Insurance payments for a well-known International Bank in Colombia. This development, carried out on Oracle and SQL Server databases, allowed the unification of the core business, which streamlined the processes of consultation, renewal, and sale of new policies.
