Problem

Disjointed spreadsheets and siloed POS tools made stock accuracy unreliable, wholesale pricing inconsistent, and leadership blind to real-time margin and inventory risk.

Solution

Designed a unified commerce platform with transactional POS, FIFO inventory valuation, wholesale workflows, scrapers for competitive pricing, and an executive analytics dashboard.

My Contribution

System architecture

Defined modular services for sales, inventory, pricing, and analytics with clear domain boundaries.

FIFO & inventory engine

Implemented cost-layer accounting and stock movement pipelines that survive concurrent operations.

Dashboard & POS UX

Built operator-focused interfaces that reduce checkout friction and elevate managerial clarity.

Price intelligence

Integrated scraping pipelines and surfaced actionable competitive pricing insights.

Challenges

  • Maintaining FIFO cost layers under concurrent multi-warehouse movements
  • Keeping POS latency low during peak checkout windows
  • Normalizing scraped pricing signals into actionable pricing strategies
  • Modeling wholesale vs retail rules without fragmenting the inventory ledger

Results

  • Single source of truth for inventory and costing across stores
  • Realtime sales and margin visibility for operations leadership
  • Reduced manual reconciliation across POS, stock, and wholesale
  • Faster pricing decisions powered by competitive market signals
