A Golang developer builds software in Go, a compiled language designed for simple, fast and concurrent programs. Most work is on backend services, cloud infrastructure and networking tools, and teams often hire one when services must be lean and easy to operate.
A backend developer builds the server-side systems that store data, apply business rules and serve applications through APIs. Hiring one is how a team secures correctness, security and room to grow in the layer users never see.
Kubernetes is an open-source platform for running containerised applications across a cluster of machines. It schedules containers, restarts failed ones, scales them with demand and routes traffic between them.
Microservices is an architectural style in which an application is built as a set of small, independently deployable services. Each owns a specific business capability and its own data, and talks to the others over the network.
gRPC is an open-source framework for fast communication between services. Strongly typed contracts are defined in Protocol Buffers and data travels in compact binary form over HTTP/2.
A Rust developer builds software in Rust, a systems language that offers high performance and memory safety without a garbage collector. Companies hire one for infrastructure, embedded or blockchain components where crashes or vulnerabilities are costly.
