In a nutshell, the platforms that I built are used by thousands of users every day. I could build web and mobile applications using React.js, Node.js, Typescript, and Serverless Computing, conforming to the principle of the least privilege (Pay-per-use AWS Solution Architect that scales indefinitely). Whenever possible, I also apply my passion for developing products with GPT-4 models, DeepLearning and Natural Language Processing.
