Luiz, a seasoned developer from São Paulo with nearly two decades of experience in languages like PHP, WordPress, and Ruby on Rails, co-founded a company called Promovaweb, which specializes in hosting and supporting Mautic, an open-source marketing automation system. He is actively involved in organizing Mautic and Elementor meetups in São Paulo, and his work spans education, training, and system integration. His interest in n8n, a workflow automation tool, emerged from a need to address customer dissatisfaction with other automation tools' pricing models. Luiz has shifted much of his background processing from Laravel to n8n, utilizing it for CRM integration, email validation, and data synchronization. Despite experimenting with other automation tools like Huginn and Airbyte, Luiz found n8n's direct JSON data handling and flexible nodes like Function, Set, and SSH to be invaluable. He uses n8n extensively for personal tasks and believes it will become a cornerstone of his future work, particularly in marketing and system integration, although he wishes for features like workflow change history.
