Go development services

Go development services for microservices and APIs, fintech and SaaS back ends, cloud infrastructure and Kubernetes tooling, high-throughput data and ad tech pipelines, network and security software, and blockchain services, with dedicated Golang developers for your team or a Go project delivered end to end.

What we build with Go

  • Go microservices and APIs

    HTTP and gRPC services on the standard library router, chi or Gin, with Connect or grpc-go, small dependency trees and single static binaries in distroless containers that start in milliseconds.

  • Fintech transaction services

    Payment processing, wallets, ledgers and transfer APIs with idempotency keys, a transactional outbox for the events they publish, and decimal types for money instead of floating point.

  • SaaS back ends in Go

    Multi-tenant back ends on PostgreSQL through pgx and sqlc, long-running workflows on Temporal, background jobs on River, and rate limits and quotas per tenant.

  • Kubernetes operators and platform tooling

    Operators and controllers with controller-runtime and Kubebuilder, Terraform providers, command-line tools on Cobra and internal developer platforms, the kind of software the cloud-native ecosystem is itself written in.

  • High-throughput event pipelines

    Event ingestion, real-time bidding and analytics pipelines on Kafka, NATS or Pub/Sub that use goroutines without leaking them, with batching, back-pressure and graceful shutdown.

  • Network and security software

    Reverse proxies, API gateways, VPN and zero-trust agents, vulnerability scanners and log shippers, built on crypto/tls and the standard crypto packages rather than hand-written primitives.

  • Blockchain nodes and indexers

    Nodes, indexers and back-end services on go-ethereum and the Cosmos SDK, with chain reorganisations handled and signing keys kept in a hardware or cloud key store.

  • Migrations to Go

    A hot or costly service moved from PHP, Python, Ruby or Node.js to Go behind the same API, with load tests before and after so the gain is measured.

  • Reviews of existing Go code

    Goroutine leaks, data races, unchecked errors and vulnerable dependencies found with the race detector, staticcheck, golangci-lint and govulncheck in a read-only review, written up as a list of risks.

Hire Go developers

  • Dedicated Go developers

    Go developers who join your team full time, work in your repositories, tracker and meetings, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.

  • Go project delivery

    A team that takes the Go project from scope to release: estimate, build, tests and deployment, with a technical lead on our side who owns the plan and the quality.

  • Go support and take-overs

    An existing Go system taken over from another team or kept running: a read-only review and a written list of risks first, then fixes and new features in order of impact.

The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

Who works on your Go project

  • Go developers

    Services, event pipelines and platform tooling

  • Cloud and DevOps engineers

    Kubernetes, Terraform and the pipelines Go services ship through

  • Front-end engineers

    React, Angular or Vue

  • QA engineers

    API and load test automation

How we work on Go

Errors are handled where they occur, never discarded; contexts carry cancellation through every call; the race detector and static analysis run in the pipeline; and dependencies stay current with advisories treated as unconditional upgrades.

Developers work in your repositories, your tracker and your process. The Ukrainian contract, payroll, invoicing and leave stay with us, and everything they write is assigned to you.

Questions about Go development

Which industries do your Go developers work in?

Fintech (payment, wallet and banking services), SaaS and enterprise software (multi-tenant back ends and APIs), cloud infrastructure, hosting and telecom (platform tooling, networking and Kubernetes operators), healthcare (data exchange and telemedicine back ends), ad tech and analytics (bidding and event pipelines), e-commerce, cybersecurity (scanners, agents and gateways), education, and blockchain (nodes and indexers).

Which Go libraries and tools do you use?

The standard library first, with chi or Gin for routing where it helps, gRPC and Connect between services, pgx and sqlc for PostgreSQL, Temporal for long-running workflows and OpenTelemetry for tracing, on the current Go release with golangci-lint and govulncheck in the pipeline.

How quickly can Go developers start?

When the right Go developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.

How do we hire Go developers through BigTree108?

Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.

Who owns the work they produce?

You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.

Need Go developers?

Tell us what the service does and where it runs. You get an answer within one business day: candidate profiles or a plan.
