About

I’m Charlie Hwang, a software engineer based in Adelaide.

I work with Go, Python, TypeScript, and AWS to build web applications and automate repetitive work. Recently, I migrated a client’s system to AWS serverless and cut their monthly costs by 93%. I currently build internal tools for companies, including systems that manage thousands of influencers and campaign records.

Before freelancing, I led a five-person team to ship a CRM system in two months and taught more than 1,400 developers through bootcamps and online courses.

This blog is where I write about engineering decisions, cloud architecture, Linux internals, and the practical lessons I pick up while building systems.
