about the project

Fexco's goals


Hire stellar talent

The team at Fexco was struggling to find high-quality software professionals from their location in Ireland.


Replace legacy software

Fexco was looking to rewrite and migrate mission-critical mature applications from monolithic, on-premise solutions to modern cloud-based software.


Modernise tech stack

Investing in modern software applications, cloud-based solutions, microservices architecture and an entirely new technology stack was among Fexco's key priorities.

The solution

In 2016, Fexco contracted Zartis to assemble an extended development team to help them achieve their goals.

It solutions

Step #1

Modernising the tech stack


First, Zartis assembled a team of three fullstack developers, quickly expanding to a total of 11, from our distribution center in Spain.


Next, our extended team migrated one of Fexco's mature applications from a monolithic, on-premise solution to a new cloud-based software using Microsoft Azure and microservices.


The new application was written in Java, using Angular for the frontend. The Azure cloud automated deployment was done using Ansible and Jenkins.

Step #2

Creating a central API


Our extended developers then moved on to supporting the creation of a Central API — one of the key priorities for Fexco Technology Solutions.


Zartis started by defining the software delivery lifecycle, quality controls and process. Next, they introduced an entirely new architecture and technology stack, including Golang, Scala, Kubernetes and Helm.


By operating as an extension of Fexco's in-house engineering department, the Zartis developers helped speed up the development of the Central API.

Step #3

Developing cutting-edge software

Our next project with Fexco involved using the Central API, Electron and Angular to rewrite a monolithic application and migrate it to the cloud.

A further ongoing collaboration with Fexco involves leveraging the Central API, a micro-frontend, Angular, Scala and Go for the purposes of a digital signature project.

The goal is to introduce a more efficient approach to the trading and financing of aviation equipment. Key elements of this project include the creation of a secure platform and a live, searchable electronic ledger with details of ownership and security interests.
