Motion Designer / Web Animator Needed for Sports-Style Big Play Animations

I need a motion designer or web animator to create a set of short, exciting “big play” animations for a browser-based interactive game. These animations will be used as event-triggered overlays during a live game presentation. They should feel like sports broadcast graphics or scoreboard highlight animations. The app will run in a web browser, so the animations need to be lightweight, fast-loading, and easy for a developer to integrate. Style Needed The animation style should be: • bold • clean • energetic • sports-broadcast inspired • readable on a TV screen • suitable for mobile and browser • short and reusable The animations should not be full-screen videos or heavy cinematic scenes. They should work as overlay graphics while the main game UI remains visible. Animation Types Needed I need animations for events such as: • score • big play • turnover • defensive stop • penalty • possession change • power-up / boost activated • halftime / phase transition • final result • generic progress or momentum update The final event names and text will be provided. Preferred Delverables Preferred delivery format is Lottie JSON, with After Effects source files included if applicable. Animations must be lightweight, transparent/overlay-friendly, scalable for mobile and TV displays, and easy for a web developer to trigger by event type. Preview MP4/GIF files may be included for review, but the production deliverables should be Lottie JSON files. Deliverables should include: • exported animation files • source files • organized file names • developer integration notes • optimized file sizes • transparent or overlay-friendly backgrounds Requirements • Must work well in a browser-based app. • Must be lightweight and optimized. • Must be visually consistent as a package. • Must support a primary accent color if possible. • Must be readable on mobile and TV. • Must be easy for a web developer to trigger by event type. Please include: • examples of similar animation work • estimated time to complete 10–12 animations • what source files are included • whether revisions are included
