Yomdel - Lead Management Platform

THE CHALLENGE

Yomdel needed to build proprietary IP - their own platform for lead generation operations and client billing - rather than relying on third-party systems. Previous attempts with UK local engineers had failed: developers either left mid-project, dragged timelines, or failed to deliver.

The complexity

• Integrate multiple chat platforms (LiveChat Inc and others) with real-time lead routing
• Build multi-tenant architecture supporting 1,000+ agencies with complete data isolation
• Handle high-performance requirements (sub-3-second response times for lead generation)
• Create multi-channel lead routing algorithms that distribute inquiries intelligently
• Develop client portal with integrated billing for pay-per-lead model
• Ensure GDPR compliance for sensitive customer data across estate agencies
• Scale to handle 10,000+ leads monthly with 99% uptime

With tight deadlines and budget constraints typical of fast-growing startups, Yomdel needed a team that could deliver complex functionality without the premium rates of UK agencies. They chose AnvilEight based on reasonable pricing, proven Django expertise, and referral trust - looking for a long-term technical partner, not just contractors.

THE RESULTS

What started in 2014 as a 6-month MVP build became an 11-year partnership powering the UK's leading estate agency live chat platform.

1,000+ Estate Agencies Using Platform

600+ Agents Active Daily

10,000+ Leads Processed Monthly

99% Platform Uptime

Business Transformation

• Market leadership achieved through proprietary software platform
• 40% more efficient than alternative solutions for estate agencies
• Constantly growing ROI enabling Yomdel to dominate UK real estate chat market
• 11 years continuous partnership proving technical and business alignment

Technical Achievements

• Sub-3-second response time for lead generation (critical for real-time chat)
• Zero downtime deployments across multi-region AWS infrastructure
• Multi-tenant architecture with complete data isolation for 1,000+ agencies

TECHNICAL CHALLENGES SOLVED

Challenge 1: Real-Time Chat Integration at Scale

Problem: Integrate multiple chat platforms (starting with LiveChat Inc) while maintaining sub-3-second response times for lead generation. With 600+ agents and 10,000+ monthly leads, latency kills conversions.

Solution: Built abstraction layer separating core platform from chat vendor APIs. Implemented WebSocket connections for real-time notifications, Celery task queues for background processing, and database optimization ensuring chat-to-lead conversion happens within 3 seconds. When LiveChat Inc proved problematic, our architecture allowed migration to alternative platforms without rebuilding core systems.

Challenge 2: Multi-Tenant Architecture for 1,000+ Agencies

Problem: How do you serve 1,000+ estate agencies on a single platform while ensuring complete data isolation, GDPR compliance, and independent performance (one agency's issues don't affect others)?

Solution: Designed multi-tenant architecture with strict data separation at database level. Each agency's data isolated with row-level security, separate access controls, and independent configuration. Schema design prevents any cross-agency data leaks while maintaining single codebase and infrastructure for efficient scaling.

Challenge 3: Intelligent Lead Routing Under Performance Constraints

Problem: Route incoming property inquiries to the right agent instantly (while chat is active) considering: agent availability, geographic territory, property expertise, historical performance, and agency hierarchy - all within 3-second window.

Solution: Engineered custom routing algorithm balancing complexity with speed. Pre-computed agent availability matrices, cached territory mappings, and optimized database queries. Algorithm evaluates multiple factors in parallel, makes routing decision in <1 second, leaving 2 seconds buffer for chat integration handoff. Handles edge cases (all agents busy, territory overlaps, VIP customers) gracefully with fallback logic.

Challenge 4: Zero-Downtime Deployments for 24/7 Operations

Problem: Estate agencies need Yomdel operational 24/7. How do you deploy new features, bug fixes, and database migrations without interrupting live chat conversations or lead processing?

Solution: Implemented blue-green deployment strategy with rolling updates. Database migrations run backward-compatible versions first, application deploys to secondary instances, health checks verify functionality, then traffic switches with zero interruption. 11 years of deployment history proves reliability - platform achieves 99% uptime while continuously evolving.

WHY 11 YEARS OF PARTNERSHIP SUCCESS

We operate as an extension of Yomdel's team with daily standups, regular sprint planning, and transparent project measurables. The COO praised our "good scrum meetings, daily updates and project plan measurables" - communication that builds trust over 11 years.

Ukraine (GMT+2) provides perfect overlap with UK business hours. Real-time collaboration for urgent issues, scheduled calls at convenient times, and same-day responses to questions. Unlike Asian teams (8+ hour difference) or US teams (5-8 hours behind), we work when Yomdel works.

UK agencies quote 2-3x our rates for senior Django developers. Over 11 years, this cost efficiency enabled Yomdel to invest more in marketing and sales rather than inflated development costs - directly contributing to their market leadership position.

We don't just write code - we understand Yomdel's business model (pay-per-lead), their market (UK estate agencies), and their customer needs (property seekers). This business context ensures we build features that drive revenue, not just satisfy technical requirements.

Currently maintained by 1 dedicated developer who knows the codebase intimately. When issues arise (SLA: 8-hour response, 24-hour resolution), we respond fast without bureaucratic overhead typical of larger agencies. 99% uptime over 11 years speaks louder than promises.
