About
I am a software engineer at LG CNS with a background in both Linguistics and Computer Science. I build AI-powered systems at the intersection of language and technology — from multilingual enterprise platforms to agentic workflows for production consumer products.
I am drawn to problems where linguistic nuance matters in engineering: designing prompts that behave consistently across locales, handling multi-language UX at scale, and building systems that work for diverse users worldwide. Outside of work, I mentor engineers on AI-native development and maintain a 2,000+ day streak on Duolingo across four languages.
