Go · Race-clean · From $20
Do My Go Homework
Go, the language they sometimes call Golang, is the one course where the autograder runs the race detector on your code. We write your Go the way the grader runs it: clean under go test -race, gofmt-formatted, every goroutine accounted for and every channel closed.

What we cover
The whole Go toolchain, not just the syntax
Go homework is graded by the tools that ship with the language. The build, the formatter, the vetter, and the race detector all live inside one go command, and your mark depends on clearing each of them. We work across the concurrency primitives, the standard library, and the modules layout your course expects.
Concurrency is where most marks move. A goroutine starts with a single go keyword and costs a few kilobytes, so a Go program runs thousands of them at once. The catch is coordination. We model the work with channels and a select loop when the design is message passing, and we reach for a sync.Mutex or a sync.WaitGroup only where shared state is genuinely unavoidable. Each choice comes with two or three viva questions so you can defend it.
The rest of the toolchain is non-negotiable, by design. gofmt has zero configuration, so there is one correct layout and graders run gofmt -l to catch any file that is not it. go vet flags printf bugs and copied locks before runtime. The race detector needs no install, it ships in the standard toolchain, and a submission that is output-correct but racy still fails. We clear all three, plus golangci-lint where the rubric runs staticcheck and errcheck on top.
The deliverable
What a typical Go assignment looks like
A Go assignment is a small module, not a single script. It is a handful of .go files plus a go.mod, and a hidden test file the grader drops in beside your code. Most coursework we get lands in a 150 to 500 line band across 2 to 6 files. The MIT distributed labs run longer, 300 to 800 lines and up per lab. These four shapes cover the work.
A concurrent sort or the dining-philosophers problem
A merge sort that splits an array into 4 sub-arrays across goroutines and recombines them over a channel, or the dining philosophers with the synchronization fixed by mutexes or channels. This is the UC Irvine Concurrency in Go staple, graded -race-clean with no deadlock.
A producer and consumer pipeline with channels and context
A fan-out, fan-in pipeline where workers read from one channel, write to another, and cancel cleanly on a context deadline. Every goroutine has to exit, so nothing leaks, and every channel has to close. The grade rides on the select loop and the cancellation path, not just the result.
A REST service in net/http with no framework
Handlers registered with http.HandleFunc or a ServeMux, JSON parsed with encoding/json, the right status codes returned, and every err checked. The standard-library web service that intro server courses assign before they let you touch a router library.
The MIT 6.5840 distributed-systems labs
The graduate staple: implement Google MapReduce, then the Raft consensus protocol, then a key/value service on top, all in Go. The course harness runs each lab under network-unreliability simulation and the race detector, so partial credit is rare and the format match is strict.
Course context
Go assignment help, scoped to your course
Go shows up at two levels of the curriculum, and each one grades differently. We match the package layout, the go directive, and the test harness your course runs. The deliverable includes the go.mod, the 50/50 split, and a sheet on why a given channel is closed by the producer and not the consumer.
Concurrency and language courses
The intro home for Go. UC Irvine Concurrency in Go, part of the Programming with Google Go specialization, ships the goroutine, channel, and dining-philosophers work. Many modern-languages electives use Go as the CSP case study alongside its standard-library web labs.
Distributed and graduate systems
The advanced home. MIT 6.5840, formerly 6.824, runs five Go labs through MapReduce, a KV server, Raft, a Raft-backed fault-tolerant cluster, and sharding. The course harness tests every lab under network unreliability and the race detector.
The grading convention is consistent across both. Gradescope drops hidden _test.go files beside your package, so the exported names have to match exactly. The grader runs go test -race as a hard gate, treats gofmt -l and go vet ./... as pass-or-fail style checks, and runs MOSS for cross-submission plagiarism. We clear all of them before you submit.
Go homework help
Where Go homework goes wrong, and the fix
Six failure modes account for most of the marks Go students lose after the code already compiles. Each one is a named, mechanical fix, and we apply it before delivery. The pattern is the same every time: reproduce the failure under the toolchain, trace it to the goroutine or channel at fault, and close the gap.
A data race that go test -race flags red
Two goroutines touch the same variable with no synchronization, so -race prints conflicting stack traces and fails the run even when the output looks correct. We guard the shared state with a sync.Mutex, or pass ownership over a channel so exactly one goroutine writes at a time, then re-run -race until the report is silent.
A deadlock: all goroutines are asleep
A send on an unbuffered channel with no receiver, or a WaitGroup that never reaches zero, and the runtime panics with fatal error: all goroutines are asleep. We match every send with a receive, close channels when the producer is done, and pair every wg.Add with exactly one wg.Done so the program terminates.
A goroutine leak that grows memory until it degrades
A goroutine blocks forever on a channel that is never closed or written, holding its stack until the process swells. We give every goroutine an exit path, a done or context.Done() channel, and make producers close so receivers drain and return.
A loop variable captured by a goroutine
Closing over the for-loop variable so every goroutine reads the final value, the classic bug on Go 1.21 and earlier. We shadow with i := i inside the loop or pass i as an argument on the older toolchain, and rely on per-iteration scoping where the go directive is 1.22 or newer.
An unchecked error or a nil dereference panic
A returned err ignored, or a nil map or interface dereferenced, and the program panics at runtime. We honor the if err != nil idiom on every call, wrap context with fmt.Errorf("%w", err) so the chain is recoverable, and make every map before the first write.
Code gofmt would reformat or go vet would flag
A bad printf verb, a copied lock, or a file that is not gofmt output, any of which most rubrics auto-fail. We run gofmt -w . and go vet ./... before delivery, and clear golangci-lint across staticcheck, errcheck, and ineffassign where the course grades on it.
The workflow
How help with Go homework works
Four steps take you from a brief to a race-clean module. You pay half to start and the rest only after go test runs green on your machine. The same named developer stays on your assignment from the quote through the final revision, so the person who wrote the select loop is the one who answers your question about it.
Send the brief and your go.mod version
Upload the spec, the rubric, the go directive your module targets, and the deadline. Name the autograder if you have one, Gradescope or the course harness.
A Go developer reads it and quotes
A developer who writes Go daily reads the brief and sends one fixed price in 15 minutes. No hourly meter, no surprise fees.
We build, then prove it race-clean
The code is written to your version, formatted with gofmt, and run under go test -race -cover ./... until the detector is silent and coverage clears your threshold.
You run it and pay the rest
Run go test on your machine, watch -race stay green, and pay the second 50% once it works. 7 days of free revisions either way.

One fixed price per Go assignment, from $20
Priced by complexity, not by a meter. A single-file deadlock fix sits at the Standard tier. A multi-file concurrency pipeline or a Raft lab sits higher. You see the number before you pay, and there are no rush fees.
Scope
Help with a full Go assignment, or just one package
The job scales to what you actually need. A whole module, written from the go.mod up, is one end of the range. A single .go file with one stubborn race or one deadlock is the other, and it is the cheapest tier we run. Tell us which, and the quote follows the scope.
The whole module
Every .go file plus the go.mod, built and tested as one package against the grader harness. The pipeline, the REST service, or the full Raft lab, delivered race-clean with the viva sheet.
One file, one problem
A single race, one deadlock, or a goroutine that will not exit. Lower commitment, faster turnaround. We patch the file, prove it under -race, and hand it straight back.

Questions, answered
Straight answers on the race detector, gofmt, versions, the labs, and the hidden tests, before you send the brief.
Will my Go code pass go test -race? +
Yes. We deliver race-clean code and you pay the balance only after it runs clean under -race on the grader tests. Every goroutine is accounted for and every channel is closed, so the detector has nothing to report.
Can you fix a deadlock where all goroutines are asleep? +
Yes. We trace the unmatched channel send or the stuck WaitGroup, then close the channels and balance Add against Done so the program terminates. A single-file deadlock fix sits at the cheapest tier.
Will it be gofmt-formatted and pass go vet? +
Yes. We run gofmt -w and go vet ./... before delivery because most rubrics auto-fail unformatted or vet-flagged code, and we clear golangci-lint where your course runs it.
Which Go version do you write to, 1.21, 1.22, or 1.23? +
Whatever your go.mod specifies. Tell us the go directive and we match it, including the 1.22 loop-variable behavior and the generics that landed in 1.18, so the build behaves the same on your machine and the grader.
Can you implement the MIT 6.5840 Raft or MapReduce labs? +
Yes. We build to the course package layout and its race-enabled test harness, including the network-unreliability cases, so the lab tests run green under the same conditions the course applies.
Can you write the concurrency with channels instead of mutexes? +
Yes. We use whichever the assignment requires: CSP channels and select for message passing, or sync.Mutex and WaitGroup where shared state is unavoidable. The viva sheet explains why each one was chosen.
Will it pass the hidden Gradescope test files? +
Yes. We match the exact package name and exported signatures so your hidden _test.go harness compiles and runs against our code, not just our own console output.
Can I explain the goroutine logic in my viva? +
Yes. Each delivery includes a short sheet answering which goroutine closes a given channel and why, plus two or three questions a TA is likely to ask about the synchronization.
