Throughout my career, I have delivered projects for clients in Brazil, Portugal, Germany, Spain, Switzerland, and the United States, helping businesses automate operations, integrate systems, and improve productivity through reliable software solutions. My experience includes integrating platforms such as Shopify, Bling ERP, Tiny ERP, Kommo CRM, Bitrix24, Jobber, Quo, Xero, Google Sheets, and WordPress, as well as developing custom systems, AI-powered applications, and business automation solutions using Python, n8n, Codex, and Lovable. I have delivered over 30 business automation projects for Brazilian companies and built more than 100 websites using WordPress, Lovable and Codex for clients in Portugal. Most recently, I completed a Freelancer.com project worth over US$5,000 involving Jobber, Xero, Quo, and Google Sheets for an American client, earning a 5-star review. Besides client work, I actively create technical content through my YouTube channel and technical blog, where I share practical tutorials on API integrations, automation, AI, and business systems.
