Tech Stack for Spotify
Its backend is mainly built with Java, and PHP is used (to some extent) for the server-side logic. Spotify uses many supplementary services, almost hundreds of them. This makes the backend architecture rather intricate. Most of these services are written in Java and Python, and the rest in Clojure and HTMl5.
The entire android app development (backend) of Spotify is segregated, in a way that each feature is assigned to a different set of developers (squad). It is called as Microservice architecture, where each Microservice is assigned a specific responsibility and a set of developers code for specific functionalities in an isolated fashion.
So if one feature fails, the other features will continue to work, as they are mutually independent. Also, since all the knowledge of one particular feature is known to one squad, it becomes easier to A/B test features, analyze the data collected, make an informed decision.
Deliveroo is a food delivery app that serves as an intermediary between customers and restaurants. Using the app, customers place (and pay for) an order, and the participating restaurant gets the information in real-time. A Deliveroo courier collects the food and delivers it to the customer. Sounds pretty simple? Not exactly, as there is a complex algorithm that makes all this look simple.
As per a survey by GlobalWebIndex, Deliveroo is the third-most-popular food delivery app in the UK, after Just Eat and Uber Eats.
The key features include:
Tailored restaurant recommendations
Advanced search filters
Customizable delivery details
There is an algorithm (Frank) behind the efficiency of the app. The primary objective of the algorithm is to minimize customer waiting time. It sets the delivery radius in a way that encourages people to order from restaurants that are based locally.
Frank constantly calculates and recalculates, to determine the best rider for a particular order. It uses Deliveroo’s historical data and various machine learning models to predict a rider’s travel time as well as an order’s preparation time.
Moreover, it processes a complex set of data to make predictions and decisions in real-time and stack orders based on these decisions. It can even tweak its response in accordance with real-world scenarios, such as travel delays.
Tech Stack for Deliveroo (Android app development)
The highlight of Deliveroo is its responsiveness. If something goes wrong with a customer’s order, then the app allows customers to pictorially report the issue (share an image).
To spare the customer care team from going through irrelevant or poor quality images, Deliveroo uses Amazon Rekognition, which accurately processes all images in real-time. It rejects hundreds of photos per week (about 1.7% of all images that users submit).
The app also uses Amazon Simple Storage Service (Amazon S3) to store the photos that go into the customer service queue.

The application has become a must-have tool for every business, be it small, medium, or large, to facilitate uninterrupted communications with its employees.
It is one of the most trending apps on the play store, and the number of users is growing at a really high pace.
