Production ReadyEnterprise Inventory & Order PlatformFull-Stack Applications

ApexFlow

Enterprise inventory and order management platform designed to streamline stock control, purchasing, fulfillment, invoicing, and reporting.

Project Overview

Growing distribution and commerce operations frequently suffer from inventory shrinkage, stock-out discrepancies, and fragmented fulfillment pipelines when managing multi-warehouse stock across manual spreadsheets or disjointed tools.

What It Does

A complete full-stack enterprise operations platform connecting catalog management, multi-warehouse inventory ledgers, purchase orders, customer fulfillment, invoicing, and payments into a single unified business management suite.

Key Capabilities

Strict double-entry inventory ledger preventing stock drifting and phantom availability
Finite state-machine order processing from creation through packing, dispatch, and delivery
Procurement workflows with supplier purchase orders, receiving docks, and vendor management
Billing subsystem generating PDF invoices, payment tracking, and balance settlements
Hierarchical Role-Based Access Control (RBAC) isolating permissions across teams

Engineering Highlights

  • Designed a database-driven backend with strict transactional guarantees and atomic ledger updates
  • Built a deterministic state-machine order workflow preventing invalid operational status transitions
  • Implemented secure JWT authentication with refresh token rotation and granular permission checks
  • Developed responsive, high-density operational data tables with sorting, filtering, and pagination
  • Architected clean REST API services connecting web clients with database models
