WORK.

I build software, automate workflows, and connect the systems behind them.

AI integrations, product development, and connected devices. Here’s what I build, the decisions behind it, and what I’m learning.

Build. Connect. Keep learning.

From a workflow to a product.
From a phone to a device.
From the idea to the details.

/01The person

A builder.
Across layers.

I’m Haqi, a developer and systems builder based in Tegal, Indonesia.

I work across web apps, automation, AI integrations, and connected devices. I enjoy turning everyday problems into working tools—and figuring out how those tools behave when something goes wrong.

I share the work, the decisions, and the things I’m still learning. You can also explore business integrations at Adaptasi AI.

01

AI & workflow integration

Voice workflows, API boundaries, and tools that connect everyday operations.

02

Product & platform engineering

Identity, permissions, and the interfaces that help products work together.

03

Mobile & connected devices

Android, BLE, firmware updates, and experiments that leave the browser.

/02Selected work

/04Field notes

Decisions.
Discoveries.

01
AI / ARCHITECTURE

Why I put an API between AI and the database

A clear API boundary makes permissions and tenant context explicit. Here’s the reasoning behind that decision.

HOMELAB / OPERATIONS

What an immutable homelab taught me

Building with Talos changed how I think about reproducibility. A field note from my June homelab setup.

TOOLS / CURIOSITY

A small detail that made a developer tool useful

Trying Terax, noticing how the terminal and file panel work together, and paying attention to everyday friction.

/05Beyond the keyboard

A different
kind of flow.

Outside the keyboard, you’ll often find me cycling or enjoying the outdoors.

That curiosity carries into my experiments with mobile apps and connected devices, including RideNav. Some days the best field notes start with a ride.

Let’s build
something
together.

Have a workflow to untangle, a product to build, or an experiment worth exploring together? I’d be glad to compare notes.
