Hi! I'm Thanarat Kuawattanphan

Hi there. I’m Thanarat Kuawattanaphan (also known as Earthchie) - a software engineer, entrepreneur, and wine enthusiast.

👨‍💻 About Me

At my core, I’m a software engineer passionate about building things at the intersection of web, blockchain, digital identity, and IT security. On productive days, I push code to GitHub - usually systems that make life better for people (and by “people” I mean developers too, not just end users).

Beyond that, no matter how broke it makes me, I still strive to be a wine enthusiast. I’ve tasted many bottles but never quite moved on from Valpolicella, Piedmont, and Bourgogne. I lean heavily Italian, especially Valpolicella - I love the style, the grape blends, the terroir, and importantly, their use of Slavonian oak. It’s so smooth and elegant I can’t pull myself away.

My journey spans traditional web development, blockchain technology, and creative tooling. I used to enjoy writing on Medium, then suddenly stopped for years because I got lazy. Going forward, if I find the motivation, I’ll probably write here instead.

🚀 Open Source Projects I’m Proud Of

jquery.Thailand.js ⭐ 691

The best Thai address autocomplete plugin - no server-side required. It helps thousands of websites auto-fill Thai addresses (province, district, sub-district, zip code) with ease. Written in pure JavaScript with zero backend dependency, it’s one of the most popular Thai developer tools on GitHub.

BlindSignature.js ⭐ 14

A Blind Signature concept brought to life, making anonymous voting on the blockchain a reality. A core component of secure e-election systems where voters can cast ballots without revealing their identity. Truly anonymous voting!

Major Media Appearances

Note: For clarity, some news outlets have spelled my name slightly differently (e.g. “ธนรัตน์ เกื้อวัฒนาพันธุ์”, “ธนารัตน์ กัววัฒนาพันธุ์”). The correct spelling is ธนารัตน์ กัววัฒนาพันธ์.

📝 Writing & Content

I write about technology and share knowledge through various channels:

• Medium (@earthchie) - haven’t written there in ages, but used to enjoy covering software development, e-election implementation, smart contracts, and technical articles.
• This blog (ihere.earth) - trying to get back into writing after years of just posting on Facebook instead.
• Notable articles:
  • “แนวทางการ implement ระบบ e-Election” - Implementing e-election systems with blockchain
  • “ระบบ Auto Complete ที่อยู่ไทย อย่างที่มันควรเป็น” - The story behind jquery.Thailand.js

💻 Technical Skills

Honestly, ever since AI came along I can barely code on my own anymore. I’m kind of useless now.
