Currently, I work on designing solutions and developing applications that have a direct impact on the daily lives of millions of users, focusing on scalability, availability, consistency, and performance.I have experience as a backend developer, working with agile development methodologies and various technologies, including NodeJs, NestJs, APIs (REST), Docker, Kubernetes, Git, microservices architecture, messaging systems (Kafka, SQS, SNS), databases (MySQL, PostgreSQL), testing frameworks (JUnit5, Mockito), cloud services (GCP, Cloud Run, Cloud Functions, Cloud Build, AWS EC2, AWS RDS, AWS S3)... and whatever else is necessary; after all, technologies are just tools to solve real-world problems.
