engineering intern @keychain

i'm currently an engineering intern at keychain, where i build ai-powered data pipelines, classification systems, and internal dashboards. previously, i interned at mastercard automating test suites for global payment platforms.

i care deeply about shipping fast and building things people actually use. i published light-hooks, an open-source npm package with 18 react hooks, and built cauldron, a video generation tool that hit 100k+ views in its first month. beyond personal projects, i've delivered 15+ client projects under nda.

you can find me on github, linkedin, or reach me via email.
