Varner

Developed a new integration system at Varner to synchronize inventory data between M3 and Sitoo POS across 1200 stores. The project involved creating a robust, scalable solution to manage inventory updates and enhance customer service capabilities.

Key Responsibilities:

• Designed and implemented the M3-Sitoo POS integration system by developing an Azure Function for processing inventory updates from an Azure ServiceBus Queue
• Created a CLI tool to assist developers with specific processes
• Implemented infrastructure as code using Terraform, Spacelift, and CDKTF
• Established monitoring systems with Application Insights and Grafana
• Developed comprehensive documentation using Backstage
• Contributed to API development for customer service
• Assisted in the transition to a new loyalty system (Voyado)
• Improved customer administration solutions

Notable Features:

• Scheduled inventory synchronization across 1200 stores
• Scalable Azure-based architecture for handling large volumes of data
• Developer-friendly CLI tool for streamlined processes
• Comprehensive monitoring and observability setup
• Infrastructure as code for consistent and repeatable deployments

Project Impact:

• Enhanced inventory accuracy across Varner's extensive retail network
• Improved developer productivity through custom CLI tools and well-documented systems
• Facilitated better customer service through improved API capabilities and loyalty system integration
• Demonstrated proficiency in cloud-native development and DevOps practices
• Contributed to the modernization of Varner's tech stack and operational processes
