About Gabriel

I am a software engineer and cloud architect with over 10 years of experience building end-to-end digital products. My focus is on AI, AWS, software architecture, and full-stack development, helping to transform ideas into scalable, maintainable solutions aligned with business objectives.

I work on designing architectures on AWS, developing backend and frontend, and integrating Artificial Intelligence solutions into products and internal processes. I have experience building web and mobile platforms, microservices-based systems, and cloud solutions with a focus on scalability, security, observability, and operational efficiency.

In AI, I have developed internal assistants, automations, and LLM-based workflows for support, information analysis, and process optimization. On AWS, I primarily work with services such as CDK, Lambda, ECS, API Gateway, RDS, DynamoDB, S3, Cognito, and CloudWatch. At the full-stack level, I usually work with TypeScript, Node.js, React, React Native, GraphQL, and PostgreSQL.

I can contribute both in technical definition and architecture, as well as in direct implementation, supporting from an MVP to the evolution of more complex platforms.
