Go (Golang) development for APIs and back-end services
Go is our pick for back ends that need to be fast, simple to run and easy to deploy: APIs, integration services and background workers, shipped as small Docker containers.
What we build
What we build with Go
Product APIs
REST APIs behind customer apps and admin panels, with authentication, validation and tests.
Integration services
Services that talk to payment, government or partner APIs and keep your data in step.
Workers and jobs
Queues, scheduled jobs and data processing that run quietly in the background.
Why Widle
Go back ends that just run
We pick Go when a back end has to be fast, cheap to run and boring to deploy. It’s what Oparko’s customer and admin APIs run on.

Where we use Go
Go FAQs
When do you choose Go over Node.js or Python?
For back ends where speed, low memory use and simple deployment matter most. We use Python for AI and data work and Node.js when the team is already JavaScript-first.
Which databases do you use with Go?
Usually PostgreSQL, MySQL or MariaDB, whichever you already run. Oparko runs on MariaDB.
Can you take over an existing Go codebase?
Yes. We start by reading the code and the deployment setup, then agree priorities with your team.
