Build Automated PDF Data Extraction Module for Existing CodeIgniter 4 (PHP) System with Database Integration

We are looking for an experienced CodeIgniter 4 + PHP developer to create a reusable module that will be integrated into our existing CodeIgniter 4-based internal web application. Project Scope The module must automatically process scanned PDF inspection reports that are uploaded through our current system, extract structured data using OCR, and save the results directly into our database. About the Documents PDFs are scanned (image-based, not searchable) Layout is always identical (fixed template) Contains key-value fields, measurements, checkboxes, structured tables/sections Goal – What the Module Must Do When a new PDF is uploaded to our CodeIgniter 4 application, the module should automatically trigger and: Perform OCR on the scanned document Extract predefined fields using fixed-position/template-based logic Detect checkbox states (checked / unchecked) Parse values (text, numbers, units, dates, etc.) Validate the extracted data Save the structured data directly into our existing database tables using CodeIgniter 4 models and Query Builder (or return clean JSON if needed for further processing) Technical Requirements (Must be CodeIgniter 4 native) The solution must be developed as a proper CodeIgniter 4 module / library / service (using CI4 namespaces, config, models, services, events, etc.) Full compatibility with CodeIgniter 4 (latest stable version) PHP 8.1+ Must use our existing database connection (CodeIgniter 4 Database library / Query Builder) Clean, well-documented, testable code following CodeIgniter 4 best practices Must be easily installable via Composer and integrable into our current application OCR & Extraction Requirements OCR experience required (Tesseract OCR, AWS Textract, Google Document AI, Azure Form Recognizer, or similar) Image preprocessing (deskewing, noise removal, contrast enhancement) Template-based / fixed-layout extraction (preferred over pure AI parsing because layout never changes) Reliable checkbox detection Data validation and error logging Legal & Compliance Requirements Use only legally compliant, properly licensed technologies No pirated, cracked, or unlicensed software All components must be suitable for commercial / business use If using external cloud OCR services, they must be officially supported APIs with proper data protection compliance The module must not store or send documents outside our system unless using an approved, contract-covered cloud service Important Legal Note: All PDFs are internally generated and owned by us. They are used strictly for internal operational purposes. No third-party copyrighted material is involved.
