Case Study

Global Food Distribution Management System
Migrating a €10M/month monolith to cloud-native microservices — without a single minute of downtime.
The Challenge
Legacy .NET Framework monolith
The existing system was built on .NET Framework — aging, difficult to deploy, and hitting scaling limits as the business grew across Ireland.
High-stakes migration
Processing €10M/month in food distribution orders with 200+ B2B users. Any downtime meant real revenue loss and broken supply chains.
Team scaling
Needed to grow the engineering team while simultaneously rebuilding the platform — without disrupting ongoing delivery.
The Solution
A modern, cloud-native architecture built for scale and reliability.
.NET Core + ABP Framework
Clean architecture patterns out of the box, with modular design enabling independent service development and deployment.
Azure Kubernetes Service
Container orchestration with auto-scaling, self-healing, and blue-green deployments for zero-downtime releases.
Terraform IaC
Infrastructure as Code for repeatable, version-controlled deployments across development, staging, and production environments.
Event-Driven Architecture
Decoupled services communicating via events, enabling independent scaling and graceful failure handling.
CI/CD Pipelines
Automated build, test, and deployment pipelines reducing release cycles from hours to minutes.
Strangler Fig Pattern
Incremental migration strategy — replacing monolith components one by one while keeping the system running.
My Role
Architecture & Technical Leadership
Designed the microservice architecture, defined service boundaries, and made key technology decisions (AKS, ABP, event-driven patterns).
Team Building & Mentorship
Led a 12+ member team including junior developers. Organized DevOps workshops, defined OKRs, and created career growth paths.
Migration Execution
Executed the Strangler Fig migration over multiple phases, ensuring zero downtime and continuous feature delivery throughout.
Infrastructure & DevOps
Set up Terraform-managed AKS clusters, CI/CD pipelines, monitoring, and alerting. Established DevOps culture across the team.
Results
Measurable impact across business, technology, and team.
€10M/month
Revenue processed with zero downtime during the entire migration.
200+ B2B Users
Across Ireland, with architecture ready for US and European expansion.
Minutes, Not Hours
Deployment time reduced from hours of manual work to automated minutes.
Team Growth
Junior developers grew into confident service owners through mentorship and hands-on experience.
Multi-Region Ready
Terraform IaC enables one-command deployment to new regions as business expands.
DevOps Culture
5+ workshops delivered, shifting team mindset from manual ops to automation-first.
