- Implemented core features such as: video recording in AR try-on app, 3D viewer external API, adaptive camera zoom
- Designed and implemented a large-scale solution that precisely calculates the inner ring diameter of each 3D model. Used for scaling models and ensuring the right appearance and behavior in AR try-on
- Solved critical narrowly focused bugs such as:
    - page reload due to resource usage spike on iOS Safari
    - inconsistencies between video codecs on different browsers
    - complicated legacy behaviors
- Worked with integration of computer vision solutions (mediapipe, teed) into AR try-on app
- Solved problems in each part of the codebase - from 3D viewer and AR try-on apps to NestJS backend and NextJS website
- Consistently done code review and refactoring

❄️ Investors decided to freeze the project.
