Build Java/Spring cloud services for an IoT platform, including REST APIs, microservices, WebSockets and multithreaded client/server components; also test, debug, deploy, and document the architecture.
"Design code in Java for a SaaS cloud platform, to be used for IoT data analytics, reporting, and smart home infrastructure management."
Tech stack maturity
Mainstream Modern
The stack centers on Java/Spring Boot, REST, Docker, AWS, and microservices with MongoDB and WebSockets, which is a widely adopted modern enterprise/cloud stack rather than bleeding-edge or legacy.
