Strong hands-on experience with AWS Serverless (Lambda, S3, API Gateway)

Proficiency in Nodejs for backend development

Solid understanding of cloud-native architecture and distributed systems

Experience working in Agile environments with CI/CD pipelines

Experience building modern front-end applications with React / ReactJS (Nice to have)
