NYC Real Estate Agency

The whole system was hard to manage and almost impossible to support. It contained over a million lines of code — for example, a single login page had 13k lines.

Our team handled the code-cleaning process by rebuilding the core functionality of old features. We implemented code refactoring and changed the duplicated code with the programming patterns. This allowed us to reduce development and testing time due to the usage of the existing and tested solutions.

We also changed the approach for solution-building and used ready-made software aligned with industry standards (Entity Framework Core). As a result, we reduced the overall amount of code to roughly 140k lines and achieved better system performance. We empowered the product with advanced solutions that are more secure, efficient, and easier to support.

The mix of outdated technologies slowed the system and caused significant security issues. We migrated the portal to modern React, the latest .NET version, and implemented new features and UX. We also changed the app’s architecture. This allowed us to improve performance, reduce hosting costs, and make the system responsive, fast, mobile, and user-friendly.

We found and fixed the product’s security issues and managed the technical debt.

After the code refactoring, we covered the system with unit tests and Dependency Injections (the code was not unit-testable before). It led to 80–100% unit test coverage for the main product and subprojects.

We developed all supporting technical documentation, including user and development guides, use cases, and unit test examples. We also prepared detailed and descriptive pages based on business rules, main user stories, and possible outcomes of different behaviors in Confluence.

We also prepared code guidelines for the in-house development team to maintain and support the solution.

With the help of our extensive network of recruiting agencies and strong market reputation, we assembled a dedicated team in 42 days (compared the average of 52 days for hiring a senior-level team of this size). This allowed us to avoid delays in the development process and start working on the customer`s project in the shortest possible time.

We established strong management and administration processes by setting up the Agile Scrum processes. As a result, our team was more cost-efficient while maintaining a high level of productivity.
