Backend developer in Go, Bali, Indonesia
I am Khairul Aswad, a backend developer working in Go. I came from networks into software, and I build the parts users never see: APIs, data models, and the tests that prove they hold up. Based in Bali, Indonesia, and open to relocating for the right backend role.
Currently building in Go, PostgreSQL, Redis, and Docker. The work below is linked to its repository wherever one exists.
GEOSEARCH radius 1 kmsos-allert-be, Redis geospatialPOST /topup/initializeewallet, Go and Fibermigrate up, then seedstockflow-test, PostgreSQLThree habits, each tied to a project below. If a habit does not show up in the work, it does not belong here.
In the SOS alert backend, a user location is stored once, as a Redis geospatial entry, and the database is only hit when an alert is actually triggered. The shape of the data decides what the rest of the system has to do.
Distance, expiry, and filtering are where the SOS feature can quietly go wrong, so the repository and use case tests come before the notification gateway. The gateway starts as a stub that logs its recipients, and the real provider comes later.
The e-wallet API is split into clean-architecture layers so a top-up, a transfer, and an email notification can each change without pulling the others apart. Small surfaces are easier to review, and easier to trust.
Newest first. Every repository link goes to the code as it stands on GitHub. Client work without a public repository is marked as such.
A realtime SOS feature that notifies users within 1 km of an alert, shows the reporter location, and records triggered alerts for audit.
A Go backend for products, stock movements, and sales orders, run locally with Docker Compose and PostgreSQL.
A tailored sales and inventory web solution built to match the business process, with a Svelte frontend and a Golang backend.
An e-wallet service in Go using clean architecture, with top-up, transfer, login, and transaction notifications.
A shipping-provider feature that calculates cost from weight and distance, built with dependency injection and unit tests.
More on GitHub, including learning repositories: golang-redis-api-example, golang-rabbitmq, and simplebank.
This section loads the newest public repositories from GitHub every time the page opens. It does not change the selected work above. Each paragraph uses that repository's own description or README, plus its language and last push date. If a repository has no description or README, the paragraph says only what GitHub records about it.
