Motion Designer – SaaS Product Demo Video (After Effects or Jitter)

I need a short 20-second animated product demo video for a SaaS platform. The style is clean, modern UI animation -- similar to what you'd see on a B2B tech or AI software landing page. Think smooth card transitions, typewriter text effects, and layered UI panels with subtle 3D perspective.
I have reference screenshots from an existing video showing the exact aesthetic I want to match. You will not be starting from scratch -- the style guide, color palette, and content are clearly defined.
What You'll Be Creating
A 20-second MP4 video featuring:

Animated UI cards sliding and fading in on a light grey background
Typewriter text effect in a search bar
A second panel (blue background) sliding in from behind at a perspective angle
Product result cards appearing in a grid
Smooth, professional easing on all transitions
Accurate on-screen text provided by me

Requirements

Strong portfolio showing SaaS, app demo, or UI animation work (this is required -- general motion graphics or logo animation portfolios will not be considered)
Proficiency in After Effects OR Jitter
Able to work from reference screenshots and a written storyboard
Delivers a clean 1920x1080 MP4 file
Responsive communicator -- I expect a draft within 3-4 days of briefing

Nice to Have

Experience with Figma (assets may be provided as Figma frames)
Familiarity with B2B/SaaS visual style

How to Apply
Please include:

2-3 examples of UI animation or product demo work (links or video files)
The tool you would use (After Effects or Jitter) and why
Your estimated turnaround time and rate for a 20-second video

Applications without a portfolio will not be reviewed.
