About
Hi, I’m Andre Antunes Vieira. With over 17 years of experience in software development and a strong focus on JavaScript, TypeScript, and modern frameworks like React/Next.js and NestJS, I have spent nearly a decade leading tech development in EdTech. I’m passionate about innovation and really enjoy working in agile, forward-thinking environments that align with my values and mission.
I’ve also accumulated solid experience in the FinTech sector, developing AI-powered tools and high-standard security practices. I’m skilled at cross-team collaboration, architecting scalable microservices, and have hands-on expertise with cloud technologies and AI/ML integrations. I’m eager to bring my skills to a company that values purpose-driven development and cutting-edge technology.
