Welcome to my digital garden – a space dedicated to exploring technology and sharing what I’ve been learning. This site reflects my passion for continuous learning and open-source software, wherein I document my journey, offer insights, and dive into miscellaneous topics that reflect my interest. My goal is to maintain a corner of the Web for self-expression focused on valuable, distraction-free content. I believe in the power of the Open Web as a platform for sharing knowledge.

♠ Previously. My dual-review skill runs two independent LLM reviewers over a commit / diff / PR, validates every finding against the code, and hands back one action plan — Blockers, Important, Suggestions. Recently I added a flag...
