Go, or Golang, was designed at Google for large networked systems, and it shows: goroutines make concurrency cheap, the standard library ships a production HTTP server, and a service compiles to one binary. This path teaches Go first, then the SQL, Linux, Git and Docker every Go backend job assumes. Free, in your browser, with a certificate for each course.

A variable is a named container that stores a value you can reference later in your program.
In Python, you create one by writing the name, an equals sign, then the value you want to store.
The value can change over time. Reassigning the name simply points it to a new value.

go build produces a single executable with no runtime or interpreter to install on the server, and it starts in milliseconds. That makes Go services quick to roll out and small to containerize, which is where this path ends.database/sql) without a framework. The trade-offs: error handling is explicit, an if err != nil after every call that can fail, and the ecosystem favors small libraries over one framework that decides everything, so you assemble more yourself.net/http is a production-grade server, and its router matches methods and path parameters (GET /users/{id}), which covers much of what a framework's router offers. Gin, Echo and Chi are the popular picks when you want middleware and routing helpers on top. This path teaches neither approach yet; it teaches the Go they are both built on.Python if you are new to programming, or if you also want the language of data work and quick scripts; Go if you want compiled, typed services with a lot of concurrency, or a job close to cloud infrastructure. Only step one changes: the SQL, Linux, Git and Docker steps are the same in both versions, and a second language comes much faster once you have finished the first.
Because a Go service is cheap to run and easy to ship: one binary, a small container image, fast startup and modest memory, with concurrency built into the language rather than added by a framework. The ecosystem fits too: gRPC and Protocol Buffers have official Go implementations, and Kubernetes and much of the tooling around microservices are written in Go, so the libraries and examples are there.
Starting from zero, at an hour a day: the Go course takes about seven weeks, SQL two to three, and Linux, Git and Docker about a month together, so three to four months for the foundations on this path. Job-ready usually means one real service on top, an HTTP API with a database, tests and a Dockerfile, which in Go needs little beyond the standard library.
Yes. Every course on it is free: the Go lessons, the SQL and terminal exercises, Bugsy's hints and a certificate for each course you finish, each verifiable at its own URL. Go compiles and runs server-side, so there is nothing to install.
Yes. Finish every step and you get one free certificate for the whole Backend Developer path. It lists each course you finished on the way, and links each course's own certificate, so anyone can check every skill it names. You can add it to your LinkedIn profile. It is a certificate of completion from Coddy, not an accredited qualification.
