Golang Development with gRPC in Romania

What we write in Go

We reach for Go when throughput and cost per request matter. Typical deliveries are HTTP APIs in Gin or Fiber, internal services that speak gRPC over Protocol Buffers contracts, queue consumers and agents that run on your own servers. We also build command-line tools for repetitive operations and metric exporters. Code comes with clear modules, correct context cancellation, table-driven tests and a static binary that fits in an image of a few megabytes.

• REST APIs with Gin or Fiber, validation and rate limiting
• gRPC contracts generated from Protocol Buffers
• Event consumers and background workers
• CLI tools and agents for day-to-day operations

Running Go on 4hosting

Because a Go service is one binary without a runtime, the container image is tiny and startup is almost immediate. On a VPS with Docker we place it behind a TLS reverse proxy and keep the database on a private network. When the number of services grows, we move to k3s or Kubernetes with resource limits, health probes and rolling updates. Dedicated servers with 6 to 48 cores handle workloads with many concurrent goroutines comfortably.

When Go is the right choice, and when it is not

We do not propose Go for everything. It pays off with traffic peaks, event processing and infrastructure bills that grow faster than revenue: low memory use, cheap concurrency and a binary that does not depend on its environment. For a classic back-office full of forms and reports, a framework with a broader ecosystem is usually the better fit, and a strong team in another language rarely benefits from being split. We tell you this at scoping, before the first line of code.

Where your monthly hours go

Requests start in the DevOps Services section of the client panel with the deadline you propose. On Go projects the hours typically fund profiling and allocation cuts, carving a module out of a monolith, replacing loosely structured HTTP calls with gRPC, patching dependencies and integrations with invoicing, courier or ERP systems. The allowance is per calendar month, unused hours are not carried over, and anything above it is accepted and billed separately by the hour.

How we work

1. Share the context

   Open a request in the client panel with the repository or a service diagram, and propose the delivery date that fits your release plan.

2. Set a resource budget

   We agree API contracts, CPU and memory limits, a latency target and the effort in hours, then tell you what the monthly allowance covers.

3. Build in a container

   We write the service, add tests and metrics, build a multi-stage image and start it on a test environment that mirrors production.

4. Hand over for operation

   You receive proto files, endpoint documentation, run manifests, a metrics dashboard and a report of the hours used from your allowance.

Frequently asked questions

• What is Golang and what is it used for?

  Go is a compiled language created at Google, with a small syntax, garbage collection and lightweight concurrency through goroutines. It compiles to one static binary, which makes container deployment simple. Typical uses are network services, infrastructure tooling and event processing.

• Gin, Fiber or Echo: which Go web framework should we use?

  Gin has the largest ecosystem and choice of middleware. Fiber feels familiar if your team comes from Express-style frameworks. Echo is a solid middle path. We choose by your team's habits and the libraries you must integrate, because performance gaps rarely decide a business API.

• Go or Java for microservices?

  Go starts instantly and uses little memory, which suits many small instances or frequent scaling. The JVM ecosystem is richer for enterprise integration and batch work. If your team already lives on the JVM, the gain from a rewrite is often smaller than its cost, and we calculate that with you first.

• How do I deploy a Go service on a VPS or Kubernetes?

  On a VPS we run the binary in a Docker container behind a TLS reverse proxy. On Kubernetes or k3s we add resource requests and limits, liveness and readiness probes and rolling updates. Manifests live in git, and rolling back to the previous version takes one command.

• Where do I find Golang developers in Romania?

  The pool is smaller than for older mainstream languages, especially outside Bucharest and Cluj-Napoca, and search results are mostly job ads. We do not place staff. We deliver code with a predictable structure, tests and documentation so your own team can take it over without depending on us.

• How many programming hours are included each month?

  It depends on the plan: 1–8 hours on VPS, 5–10 hours on dedicated servers, 10 hours on GPU servers, and 1 hour on cPanel from the Advanced plan. You request them in the client panel and propose a deadline, and anything over the allowance is billed separately by the hour.
