Lizza (YC22) is a startup based in Mexico that is revolutionizing how businesses sell to their customers directly on social media platforms like Instagram or WhatsApp, by providing a suite of tools for payments, shipping, messaging and marketing.

The Challenge: A limiting legacy monolith on Firebase

Before adopting Encore, Lizza’s e-commerce platform was built using Firebase. It had a large monolithic codebase, which over time had become disorganized, blurring the frontend and backend lines. This made new development slow and error-prone, ultimately making it hard to deliver features at speed while maintaining quality.

To solve this, the Lizza team wanted to move to a microservices architecture and refactor their existing application to implement a structure better suited for their domain. This meant overcoming several challenges:

  • Transitioning from a monolithic architecture to a microservices architecture to better structure their application, without slowing down product development
  • Managing the complexity of working with microservices, including observability and infrastructure management
  • Avoiding the need to hire additional engineers to solely work on DevOps and infrastructure

Picking Encore as a solution for building scalable and efficient microservices

Lizza turned to Encore as the solution to these challenges. With Encore, they were able to:

  • Easily transition from a monolithic architecture to a microservices architecture, allowing for better structure and scalability
  • Manage the complexity of working with microservices through Encore's observability and infrastructure management capabilities, without needing to hire additional engineers for DevOps
  • Streamline infrastructure management using Encore's declarative Backend SDK, reducing both cloud waste and DevOps workload
  • Deliver high-quality microservices at a rapid pace, thanks to the simplified development process

The Results

By adopting Encore, Lizza was able to achieve meaningful results:

  • Increased delivery speed by 3x
  • Reduced time spent on DevOps by 100+ hours per month
  • Successful and timely migration from Firebase to Go-based microservices, without hiring dedicated DevOps engineers

“Lizza's backend team loves Encore! We can now deliver high-quality microservices super quickly. Encore lets us offload the microservices complexity and avoid hiring additional engineers to work on DevOps.”
