Transforming Operations For A Global Luxury Real Estate Enterprise

• Strategic business consulting to optimize every work stream
• Database migration handling millions of records while preserving critical business logic
• UX/UI redesign with a scalable design system, and multi-market localization
• n8n automation consulting and implementation
• Quality Audit and established a full QA process from scratch
• Ongoing platform support, features development, and new mobile product development
   

The client is a global enterprise luxury real estate brokerage with a large digital ecosystem:

• A public customer platform for discovering properties and submitting inquiries
• A high-load internal CRM system used daily by brokers and agents
• Multi-market infrastructure with strict legal and compliance requirements
• Millions of records and thousands of concurrent users

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 What started as a simple design refresh and frontend upgrade revealed deeper challenges: outdated visual design that didn't reflect their luxury brand, legacy architecture with high operational risk, failed prior attempts, and no QA process in place.

We tackled architectural upgrades and visual modernization in parallel, scaling their team incrementally and adding expertise on the fly – from backend specialists to QA engineers who built quality processes from scratch. This partnership evolves yearly, with new capabilities like N8n automation currently in deployment.

• Inconsistent UI, and lack of a scalable design system for a luxury brand
• Legacy architecture with limited scalability and outdated infrastructure
• High operational risk due to system complexity and strict legal requirements
• Need for strong technical expertise to safely manage complex, high-load systems
   

We partnered with the client to eliminate operational pain points and cover the entire digital transformation journey, from design, complex database migration to QA, and mobile app development. 

Acting as strategic enterprise-grade technology partner, we eliminated vendor fragmentation, ensuring consistency across all development workstreams while minimizing risk and streamlining communication.

Our tech team maintained and evolved a high-load CRM platform for brokers and agents, centralizing millions of contacts, properties, and managing integrations, enforcing role-based access across countries, and unifying all business processes in a single scalable system.

• Business process centralization: All client interactions and property data unified in a single platform.
• Millions of contacts, properties, and transactions, with high concurrent usage (thousands of simultaneous users, spikes to millions of visits).
• Role-based access: Tailored permissions for brokers and agents.
• External integrations: Automated connections with multiple real estate sources.

Our team migrated a 15-year-old Oracle database to a modern PostgreSQL-based platform, a challenge the client had failed to complete twice before. Prior "big bang" migrations caused service disruptions and were rolled back under stakeholder pressure due to lost revenue.

Our phased, client-by-client approach ensured zero downtime while preserving millions of critical records and business logic.

We developed a custom Java-based migration service and executed a gradual, client-by-client rollout. This approach allowed us to validate data integrity, preserve complex business rules, and minimize operational risk while keeping the platform running for users globally. The phased migration also revealed performance issues early, allowing us to optimize before migrating the full dataset.
 

Over years of development, the system accumulated significant technical debt. The data model and queries were not optimized for growing data volumes or evolving business requirements, resulting in extremely slow operations and high database load. To maintain acceptable performance and stability, the client had to maintain an additional full database replica dedicated to heavy queries and reporting. This doubled infrastructure costs and increased operational complexity, while failing to address the root architectural issues.

Our team redesigned the data model and implemented optimizations that:

• Boosted performance: Query times dropped from 100+ seconds to ~300ms.
• Reduced costs: Lowered infrastructure needs, achieving 2x cost reduction.
• Enabled growth: Supported new features and higher data volumes without blocking operations.
   

The client's public-facing platform was outdated with inconsistent design that no longer reflected their premium brand positioning. Previous redesign attempts were purely visual Figma concepts, lacking technical implementation and scalability.

We built a design system from scratch with reusable components and unified visual language, integrated with Storybook to enable scalable page creation while maintaining brand consistency across all markets.
 

• Property Cards & Search

Designed cards with optimal information density and enhanced search functionality with AI-powered capabilities and refined filters

• Interactive Map View

Developed map displays with advanced clustering for high-density areas and privacy-conscious location handling

• Multi-Market Localization

Adapted terminology and user flows for different countries (e.g., "1st floor" vs. "ground floor"), ensuring clarity across international markets

Before OTAKOYI’s involvement, the client had no structured QA processes. Testing was handled ad-hoc by product managers, POs, and designers, with test cases scattered across Confluence. This approach led to missed bugs, inconsistent coverage, and slow release cycles, making it difficult to deliver new features reliably.

Our Quality Assurance team introduced a full QA process from scratch, integrating it carefully without disrupting the existing product. Key actions included:

• Established test management systems and a centralized test repository, replacing fragmented documentation. 
• Designed and executed load-testing scenarios for critical pages post-database migration, including GraphQL endpoints with complex relational data. 
• Introduced bug tracking and defect metrics to monitor bug leakage, ensure coverage, and improve release confidence. 
• Enabled measurable QA sign-offs for releases, embedding quality assurance into the product lifecycle.
   

Building on our proven success with the platform, the client entrusted OTAKOYI with developing a new mobile application from concept to deployment. We’re creating a mobile portal for real estate agents, bringing the full power of their brokerage management system to mobile devices. This reflects their confidence in our ability to deliver complex products that meet enterprise standards.

The collaboration continues to evolve. Our team provides ongoing platform maintenance, QA, new feature development, and UX/UI improvements. Each year brings new capabilities based on emerging needs, we're currently consulting on n8n automation integration to streamline their operational workflows.
