● Built on-top of Flutter, the Editor Engine is a closed-source application loaded in a browser that provides interactive editing of Studio documents. These documents are defined in JSON. ● Built a system for selecting, transforming, and manipulating multiple elements simultaneously, improving workflow efficiency. ● Developed a shape renderer (rectangles, ellipses, polygons) with precise corner radius control and consistent cross-format output. ● Implemented external data source integration with performance-oriented caching. ● Enhanced frame manipulation to support smooth 60FPS interactions in complex templates. ● Created a GSAP-based HTML animations output with type-safe APIs and declarative JS code generation.
