I'm Davi Nascimento, a full-stack developer with 5+ years of experience building high-complexity systems. I founded CSO Solutions in 2022 and currently serve as the sole developer responsible for the entire digital ecosystem at Croi Computadores, where I build B2B/B2C platforms with multi-agent AI integrated into WhatsApp.
My expertise lies in microservices architecture, AI automations (Claude API, Gemini), queue systems with Bull+Redis, blockchain solutions, and LGPD-compliant clinical platforms. Every project is treated as unique, with a focus on scalability, performance, and security.
