About me

Hi, I'm Sage. I build things up and break them down in the open.

In early 2021, I got my bachelor's degree in Computer Science from Universitas Indonesia. Shortly after, I worked as a Frontend Developer at a startup in Indonesia for about a year. Then I joined Torchbox to pursue my passion in open source by developing Wagtail CMS and its ecosystem. Following one of my dreams, I moved to Bristol, UK in late 2022.

I enjoy using Django and I have made some contributions to it. During Google Summer of Code 2019, I implemented a JSONField feature for all database systems supported by Django. The feature was merged and included in the Django 3.1 release. I documented my journey and spoke about it at the DjangoCon Europe 2020 virtual event and an episode of the DjangoChat podcast.

I love learning new things. Recently, I've been diving into front-end web development and trying out React, Vue, and Svelte while studying the differences between them. As an exercise, I made giscus and its component library.

I grew up in small districts of Jakarta. I spend my free time writing, reading, playing music, and enjoying time alone or with my friends and family. I also play video games occasionally.

Places

We have a world full of wonders, and it has always been my dream to see as much of it as possible. Up until 2019, I've spent most of my life in Jakarta, Indonesia, with very few short trips to visit some friends and family, or to attend events. Circumstances didn't allow me to leave Java (the island).

In 2019, I visited Malaysia to attend an event for three days. That was the very first time I left my home country. Not long after, the world went into a pandemic, so I didn't get to travel again.

Then I moved to the UK in late 2022 as part of my job. Since then, I've had the opportunity to visit many other places the world has to offer. I thought it'd be interesting to see them on a map, so here it is!

Despite living the better part of my life in Indonesia, the map shows you the sorry truth: I haven't had the chance to see much of my home country. There isn't even a marker on Bali.

If you were to ask someone about places to visit in Indonesia, I'd probably be the last person you should ask. Let's hope this paragraph won't be here for long!

    • πŸ“±Modded my cell phone

      Smartphones were very expensive and weren't as common as they are now. So, I learned how to mod my Sony Ericsson feature phone and changed the font, icons, layout, etc. For some reason, XML made sense to my twelve-year-old self back then. I also learned how to patch my phone's firmware to add new features and enable it to run ELF executables. I played around with IDA even though I didn't have a single idea about assembly instructions. Fun stuff.
