Smart PDF Form: Employment & Address History Validator

Description

We are seeking an experienced PDF form developer to design a professional, interactive PDF form that captures both employment and address history, with built-in logic to detect and handle gaps in either timeline.
Requirements:
Build a fillable PDF form that collects:
Employment history (start and end dates for each role)
Residential address history (start and end dates for each address)
Implement logic to:
Automatically detect any gaps in employment or address history
Prompt users to enter a reason for any identified gap
Prevent submission unless:
All fields are completed
All gaps are explained
No overlapping dates are present
Apply input validation rules:
Dates must be in valid format
No future-dated entries
Start date must be before end date in each section
Consistency checks between consecutive entries
Ensure the form is easy to use and works offline (no web-based elements).
Deliverables:
Fully functional, validated, and styled PDF form
Short user guide or documentation on how the validation works
Ideal Skills:
Adobe Acrobat Pro (form creation and JavaScript scripting)
Strong understanding of date logic and form validation
Experience designing user-friendly, interactive PDFs
