Nature of work
· Backend reliability and observability
Build Node.js backend architecture from scratch, turning product specs into tech specs and shipping scalable, secure, fault-tolerant services while tuning performance and coordinating releases with QA/Product/Business.
"scalability, performance optimization, and fault tolerance"
Tech stack maturity
Modern Cloud Native
Backend development today is typically built around cloud-hosted services, containers, CI/CD, and distributed systems, but AI is usually only an optional integration rather than the core of the role.
