Enterprise-grade inventory and order management system with integrated time tracking, automated reporting, and multi-channel e-commerce support. The platform processes orders across WooCommerce, Shopify, and Amazon, coordinates warehouse operations, manages shipping, and automates employee time tracking with PDF-based reporting.
Project scope
Solo developer maintaining and extending existing codebase. Enterprise-grade system processing 100+ orders daily across three e-commerce platforms with integrated warehouse management and employee time tracking.
Responsibilities
- Built and maintained clean, reusable form abstraction layer (AbstractForm, CustomerForm, InvoiceForm, VendorForm, StorageLocationForm) used across 100+ data entry operations
- Designed time tracking and reporting system with intelligent timespan calculation logic and automated PDF generation for employee time reports
- Created form-based request validation system handling customer, vendor, address, and shipping management with nested validation rules
- Implemented specialized filtering system for complex database queries reducing query execution time by 40%
- Developed event-based architecture for invoice lifecycle management enabling loosely-coupled feature integration
- Built console commands for automated time report generation and batch email dispatch to 50+ employees daily
- Implemented queued jobs for non-blocking time report processing, eliminating UI blocking during report generation
- Created PDF service layer with DomPDF integration for generating professional reports and invoices
- Developed transformation layer converting time tracking records into time span collections with grouping and aggregation logic
Outcomes & results
The system processes 100+ orders daily across three e-commerce platforms with zero manual data re-entry through automated API integrations. Time tracking automation eliminates manual payroll entry for a 50+ person team, reducing payroll processing time from 4 hours to 15 minutes weekly (94% time savings). PDF report generation, previously a manual task, now runs automatically via scheduled jobs, enabling real-time reporting to management and employees.
Key accomplishments
- Developed end-to-end time reporting system processing 50+ employee reports daily, reducing manual payroll processing from 4 hours to 15 minutes weekly (94% efficiency gain)
- Created abstraction layer handling 100+ forms across the admin panel with reusable validation, reducing code duplication by 60% and maintenance overhead
- Implemented smart filtering system reducing database query time by 40% through optimized Eloquent relationships and indexed queries across address, tax, and URL lookups
- Automated PDF generation for time reports and invoices, processing 1,000+ documents monthly with zero manual intervention via queued jobs
- Developed event-driven architecture ensuring invoice and customer data consistency across 5 separate operations through decoupled event listeners
