Lottie/HTML5 Animator for Interactive Greeting Card Template

We are seeking a skilled 2D motion designer to create a reusable interactive greeting card template. The ideal candidate will have experience with Lottie and After Effects to build a foundational template for our digital greeting card system.

Project Overview
We want the first step in our process to be creating a flexible, mobile-first template that we can replicate across multiple occasions and designs (holidays, birthdays, special events, everyday cards, etc.).

The template should include:
- A digital envelope animation (envelope appears, opens smoothly).
- A card reveal animation (card slides or pops out).
- A multi-page card format (simple page-to-page transitions).
- Tap or forward/back navigation to move through 2–5 card “pages.”
- Ability to easily update artwork, colors, and layouts for future versions.

We want this prototype built in Lottie (preferred) or another lightweight tool that delivers fast-loading, mobile-friendly 2D animations that can be embedded into a simple HTML/JS experience.

The goal:
Build ONE intelligent, reusable template, then we’ll plug in new holiday designs over time

• What You Will Create:
• A base Lottie JSON animation (or similar format) for the envelope + card-opening
• A basic HTML/CSS/JS wrapper for page navigation
• Simple instructions on how we can swap artwork/illustrations for future card versions
• Source files (After Effects, Figma, Illustrator, etc.)
• Technical Requirements
• Must load fast on mobile
• Clean, minimal code
• Smooth animations at 60fps
• Easy to replicate for new designs
