When a monolith becomes a bottleneck, starting from scratch is not always the answer.
One of the hardest challenges in software development is modernizing a system that is already running at scale and has become critical to the business.
In this case, we worked with a platform processing millions of orders for a large restaurant network. As data volumes grew, performance issues started to appear: searching through order history could take 25–30 seconds.
The solution wasn’t a complete rewrite. Instead, we evolved the system step by step: optimized data processing, moved search capabilities to Elasticsearch, started breaking down the monolith, and built a more flexible architecture for future scaling.
The result: search response time dropped to 250–300 milliseconds, while the platform gained the foundation needed for further growth.
A good example of why legacy systems are not always something you need to replace. Sometimes, they are systems you need to evolve in the right direction.
