Jakarta, Indonesia · Building with AI

I turn AI into things people can actually use.

01 / INTRO

I’m Maulfi Najir, a builder working across product thinking, conversational systems, evaluation, and the engineering needed to make ideas real.

Selected focus

Problems I keep coming back to.

Adu Cerdik

A public experiment, shared early so real use can shape what it becomes.

WKND Voice Order

A voice-first ordering prototype for testing a more natural way to move through a menu.

Conversational AI

Assistants that understand context, handle real workflows, and feel clear rather than clever.

Evaluation systems

Practical ways to test AI behavior, find weak spots, and improve quality with evidence.

Voice interfaces

Exploring how natural speech can become a dependable interface, not just a demo.

Tools for builders

Small, focused systems that shorten the distance between an idea and something useful.

Working principles

Useful beats impressive.

[ A ]

Start from reality

Understand the messy workflow before choosing the technology.

[ B ]

Make it testable

Turn taste and intuition into feedback loops the team can learn from.

[ C ]

Ship the proof

A working artifact creates better conversations than another deck.

Curious by default. Practical by necessity. Usually happiest somewhere between a rough idea and a working system.

My work sits between product, design, and engineering. I care about the details people notice and the invisible systems that make those details dependable.

Have an interesting problem? Let’s compare notes.

The best conversations usually begin with a real problem, a rough hypothesis, and the willingness to test both.
