Optimizing performance of SaaS platform

We created a SaaS restaurant and hotel management platform that helps the world's largest hotel brands create memorable guest experiences in their establishments. The Perfsol team was actively involved in optimizing the platform for future scalability.

Organizing an event with many guests can be a global challenge, even for the most experienced restaurant and hotel owners. You have to consider all the nuances, from seating options to menus considering guests' dietary needs. Our client set a goal to facilitate business processes in restaurants and hotels with the help of innovative technological solutions. Thus, we began working on a SaaS platform that includes booking, check-in, room management, and guest list management functions.

During project development, our client was faced with the need to optimize the performance and expand the capabilities of their product. To solve these tasks, they required technical consultants and a development team. First, they turned to freelance websites and specialized portals. On one of the latter, the client saw a detailed review of our work in their area of interest, which was why they chose our team.

After studying our experience in the restaurant business and getting detailed advice from a Perfsol manager, the client fully trusted our team, and we started working on redesigning the SaaS platform.

Our first priority was to conduct a detailed evaluation of the SaaS platform. Therefore, our technical consultants were the first to take on the task. Their analysis showed that the system had a monolithic code base, making it challenging to implement new features and limited flexibility. It also had outdated code that is difficult to maintain over time.

We suggested that the client switches from a monolithic code base to a microservice architecture to solve the problems. So most of the work had to be done on the server side. To do this, we involved our leading experts in the work. We also held a series of online meetings where we outlined further tasks:

• rebuild the platform to a microservice architecture;
• update the software interface for linking with other apps;
• develop and implement additional platform features;
• test and troubleshoot errors that occur.

The key challenge was that breaking the monolithic base into microservices required a complete rethinking of the API and making it larger. Our developers solved this problem by studying the logic of the server-side components. We developed the optimal API to connect external interfaces:

• apps for Android and iOS;
• POS terminals;
• client’s website.

We made every effort to ensure that the SaaS platform fully met the client's wishes and the users' needs. Our manager was constantly in touch and provided reports on each stage of the work. We also tested the developed features to ensure maximum performance and fault tolerance of the system on the server side.

We completed the project on time due to good communication between our manager and the client. During the work, our team solved the client's problem with system optimization. We migrated from a monolithic app to a microservice architecture, which allowed us to:

• improve and speed up platform performance;
• improve scalability;
• increase system flexibility.

In addition, the team successfully implemented internal and external API services to connect with the website interface, PoS terminals, Android and iOS apps. We also created a feature for custom reporting.

This cooperation was conducted in an atmosphere of complete mutual understanding. The customer highly appreciated our work, and we are very thankful for it. They noted that our team approached the work professionally and suggested a really effective way to solve their problem.
