Case Studies

challenge

The datacenter was using a licensed third-party product for switch configuration deployment and wanted to replace it with their own software, better tailored to their needs and vendor agnostic.

approach

Built a deployer app in Go running on Kubernetes, with gRPC for the backend and a React frontend for operators.

result

Automated configuration deployment to datacenter switches.

challenge

Needed a cloud backend to communicate with wallboxes and other energy devices in real time using MQTT and OCPP.

approach

Used Microsoft Orleans on AWS for an actor-based setup, with gRPC between services and GraphQL for the client API.

result

A working cloud platform that manages IoT energy devices with real-time monitoring and control.

challenge

Several core banking systems needed to be built or modernized — credit evaluation, savings accounts, fraud detection, and regulatory compliance.

approach

Built microservices on Azure and Kubernetes using C#, CQRS, and Event Sourcing for each system.

result

Delivered five systems: credit evaluation, savings accounts, anti-fraud, GDPR data cleanup, and anti-money laundering integration.

challenge

A large monolithic booking system needed to be broken up to make it easier to work on and scale.

approach

Defined distributed architecture patterns and service boundaries using C# and ASP.NET Core. Started the migration from monolith to separate services.

result

Established the architectural foundation and patterns for the ongoing transformation of the booking system.

challenge

Setting up VXLAN/EVPN networks at the datacenter was done manually, which took time and led to mistakes.

approach

Built the system from scratch in Go using DDD, CQRS, and Event Sourcing.

result

Automated the VXLAN/EVPN setup process, cutting down setup time and removing manual errors.
