As a Software Architect, I define and design complex software systems, make critical decisions, and choose the right technologies for scalability and performance. I also guide and mentor development teams, collaborating cross-functionally to align architecture with business goals. I apply best practices to create maintainable solutions, ensuring adherence to coding standards. I oversee seamless software component integration, defining APIs for communication. I optimize system performance and scalability, using tools such as Jira, Agile methodologies, and Software Testing. I have a strong background in Software Quality Assurance, having worked as a Senior Quality Assurance Engineer at NativApps Inc. and a Quality Assurance Engineer at BairesDev, where I developed and implemented testing protocols, documented and resolved defects, and ensured compliance with quality assurance standards. I have also acquired certifications in Cloud Computing and Scrum Foundation from Google Actívate and CertiProf, respectively. I am passionate about learning new solutions, technologies, and skills, and pursuing continuing education in my field of expertise. I am also goal-oriented, teamwork-oriented, and perform well under pressure. I have excellent conceptual and analytical thinking skills, and I enjoy solving complex problems and challenges. I am fluent in English, Portuguese, and Spanish, and I have a Bachelor Degree in Computer Science from UAGRM School of Engineering.
