Microservices portal across 47 clubs · PriceSmart

PriceSmart microservices portal dashboard.

The problem

PriceSmart runs 47 clubs with distributed POS systems. Support tooling was manual, per-department visibility was weak, and Colombian electronic-invoicing compliance required controls that didn't exist.

The approach

I led the development of a microservices-based web portal for near real-time data insights and per-department management. I built the support-ticket and documentation systems. I shipped audit tooling for electronic invoicing.

  • C# + SQL Server + Angular + Node.js stack with DevOps automation.
  • Power BI for executive insights.
  • Decent microservices: clear boundaries, independent deployment, observability.

The outcome

  • Far faster traceability and operational responsiveness.
  • Near real-time visibility for departments that were previously blind.
  • Easier compliance with Colombian electronic invoicing.
  • Better end-customer experience: utility features built specifically for Colombia.
