I’m Antonio Casula, a hands-on CTO, Solution Architect, Senior Full Stack and Mobile Developer with 30+ years of experience designing, building, and shipping scalable web and mobile applications across fintech, healthcare, digital media, and travel-tech. I specialize in Node.js/TypeScript and Java backends, REST API design, and modern frontend frameworks (React, Vue.js, Angular, React Native). and Mobile apps in Flutter and Ionic I have a proven track record integrating complex third-party APIs — payment gateways, real-time voice AI, video/WebRTC, and identity verification — delivering production-grade solutions on AWS and Azure.
I am a strong written and verbal communicator with Agile leadership experience, comfortable working independently or in cross-functional, distributed teams. I power AI-assisted development (Claude, GitHub Copilot, ChatGPT) to accelerate delivery while preserving code quality. I also bring security-focused practices, CI/CD, and DevOps discipline to align technology with business goals.
