- Modern architectures and Python patterns (DDD, clean architecture)
☁️ AWS Infrastructure:
- Design and deployment of scalable cloud architectures
- Expertise in managed services (Lambda, ECS, RDS, S3, CloudFormation)
- DevOps and CI/CD for reliable and automated deliveries
🎯 What motivates me:
Transforming complex ideas into robust technical solutions, prioritizing code quality, performance, and maintainability. Always on the lookout for the latest Python innovations and best cloud practices.
