I have been partnered with Mbak Wani (the founder of Kertas Kosong) since 2018, as a translator  ID-EN and EN-ID service, and also as a copywriter for the content website and letters of agreement contracts. It’s very satisfying because the services have been delivered on time during every project and its content quality is also excellent. 👍

CEO, Alamaya Bali

Penulis yang smart, tulisannya mewakili keseluruhan bisnis yang dijalankan pada project tersebut dan tidak bertele-tele. Bisa diajak sharing, diskusi dan menerima masukan. Memberikan rasa nyaman para klien sehingga membuat kami mudah akrab, ini sangat penting bagi kami karena kami tidak pernah bertatap muka. Penulis bisa mengolah data dari kami hanya berbekal image dan informasi dasar dari kami.

Senior Web Developer

I’ve been partnered with Kak Wani since 2016. Whenever I have a project about the content website, brochure, or flat, I just pass it to her. Her works are excellent. I love her works, because, before she started working on the project, she’ll analyze the products first. So, it’s not just about nice words, beautiful phrases, but more than that she can bring values into the project. Try working with her, and you’ll fall in love on how she’s doing the job!👍
