Jugger | Backend Developer A backend engineer working in enterprise solutions software since June 2021. The hands-on perspective from system design, API implementation, and production operations directly informs this site's AI, IT, and cloud infrastructure coverage. For topics outside direct professional experience—blockchain and macroeconomics—analysis is built on primary-source citations such as SEC filings, whitepapers, institutional research, and government statistics. Speculation is clearly separated from verified fact, and unverified claims are not published. AI tools assist with drafting, but every article is reviewed, revised, and verified before publication. Errors are corrected with visible notes when discovered. Contact: jjunggulee@gmail.com
