About Alexandre

Fullstack Developer specializing in AWS and TypeScript, I design and deploy end-to-end applications, whether from scratch or on existing stacks. I have solid expertise in Infrastructure as Code (IaC) on AWS, covering the entire cycle: from architecture design to production deployment.

Proactive and results-oriented, I combine technical expertise, adaptability, and effective communication to successfully carry out complex projects.

Passionate about emerging technologies, I explore and leverage cutting-edge fields such as generative AI, developing applications based on advanced models and adopting AI-augmented development practices to optimize software creation cycles. My expertise also extends to the crypto/blockchain ecosystem, with a deep understanding of industry standards and best practices, both at the development level and for the underlying protocols.
