Challenge, approach, and impact
Background
The client is a global luxury real estate brokerage with a large digital ecosystem, including a public platform for property discovery and inquiries, a high-load internal CRM used by brokers, and multi-market infrastructure with strict legal and compliance requirements, supporting millions of records and thousands of concurrent users.
Challenge
The client had an in-house team but needed specialized expertise for complex modernization. What started as a simple design refresh and frontend upgrade revealed deeper challenges: outdated visual design that didn't reflect their luxury brand, legacy architecture with high operational risk, failed prior attempts, and no QA process in place.
The client's input
1. Inconsistent UI, and lack of a scalable design system for a luxury brand 2. Legacy architecture with limited scalability and outdated infrastructure 3. High operational risk due to system complexity and strict legal requirements 4. Need for strong technical expertise to safely manage complex, high-load systems
How we built
Testimonials
Andrii Leonets, Backend Developer @ OTAKOYI

“The real migration challenge wasn’t just moving millions of records – it was that critical business logic was deeply embedded in the old database. Every workflow had to be faithfully replicated in Java, or we risked breaking core operations for brokers and agents. That’s why we built a custom migration service and rolled it out client by client: it let us validate data, preserve business rules, and minimize operational risk while keeping the platform running for users.“
