Khmer Transliteration Engine (αα»αΈαααααα) Typing Khmer on mobile has never felt as smooth as Hiragana or Pinyinβso I set out to fix that. Iβm building a Khmer Transliteration Engine (αα»αΈαααααα) that turns phonetic input into accurate Khmer suggestions in real time. Under the hood, the engine searches across three layersβexact match, prefix, and fuzzyβto always surface at least three quality suggestions. Itβs powered by curated, publicly available data and tuned for speed on-device.

He is a fast learner started as an intern and converted to full-time staff working on Cellcard App and Dealer App using Flutter. Very outstanding looking for a better solution to get all the projects completed on time and over expectations.
For a long time I organized Next.js projects the "normal" way β a big /components folder, a big /hooks folder, a big /schemas folder. It looks tidy, but every feature ends up scattered across all of them. Changing one thing means opening five folders.
