hellofresh_portfolio_02 Challenge

The demand for food delivery is growing due to our busy modern lifestyles, and the current Covid-19 pandemic has increased demand.

Extra traffic, new users, and a huge number of orders per day prompted HelloFresh to update and improve their solution. They called in iTechArt to help out!

As the HelloFresh legacy system has been becoming increasingly difficult to scale and maintain, our team was tasked with a complete product modernisation aimed at preventing possible crashes and meeting high-priority business needs.

Solution

The HelloFresh-iTechArt collaboration started with an incremental stack upgrade that introduced the use of faster and more efficient frameworks, libraries, and algorithms. Following this, we proceeded with the following:

  • We upgraded the system by building three separate microservices to handle the supplier's data and organise and manage the ingredients and recipes;
  • We leveraged a set of performance metrics to monitor the server load, optimise code and prevent system downtime;

  • We implemented source code analytics to reduce tech debt and create clean and scalable code;
  • We developed a scalable Kafka-based ETL pipeline to provide accurate and timely data set transfers within the supply chain;
  • We added logging systems for tracking errors or inappropriate access to the system.

To date, the project is still in progress. We are still working closely with the HelloFresh technical team to ensure their systems are continually improved.
