Welcome!

I'm Charles (I go by smartgoo online). This is my small personal blog. Here you'll find my writing, things I'm working on, and links to projects.

A little bit about me

My professional background is in enterprise technology. I have ~10 years of experience (as of 2026) in traditional IT, CyberSec, and business application development.

Personal and professional growth is a fascinating area to me. I find expanding thought to be amongst the most rewarding activities.

In my free time, I actively contribute to the Kaspa ecosystem as an avid enthusiast.

My current projects

Coffee Enthused — a weekly newsletter for home coffee enthusiasts, covering gear, brewing methods, roaster spotlights, and coffee news. An experiment in letting AI run the newsletter end-to-end, with me acting only as the avid-coffee-drinker feedback loop.

Kaspalytics — analytics for the Kaspa network. Now also home to my Kaspa notes and writing, which moved here from KaspaNotes and live at Kaspalytics Learn.
Kaspa Python SDK — Python bindings to rusty-kaspa, under the Kaspanet org.

GitHub — code and open-source work.

Writing

Two forms of writing live on this site:

• Essays — longer-form pieces.
• Brain Dumps — shorter, less-polished thoughts. Usually covering wide ranges of topics in bullet format.
