I'm a full-stack software engineer working on AI video creation at HeyGen:

I initially joined as an intern the summer before the last year in my cs masters program. it was too exciting to leave, and I converted to full-time immediately after my internship ended, becoming HeyGen's first intern -> new grad hire. it's a lot of fun. here's some stuff I contributed significantly to or was responsible for:
- 🚢AI studio (our video editor)
- 🚢development and launch!
- 🚢voice mirroring
- 🚢audio uploading / recording for avatar lip syncing
- 🚢third party stock image, video, and music providers
- 🚢background music
- 🚢a new video editor for our video agent
- 🚢an interactive voice clone creation experience
- 🚢emotion generation for voice clones
- 🚢voice library: better accent and emotion support, dynamically generated previews, user customizations
- 🔧implemented observability across frontend and backend voice domain
- 🔧cut down errors across critical voice endpoints by 50%
- 🔧improved frontend performance of voice features, in some cases from 15s to <1s load time
