Case Studies
Representative anonymized examples based on the types of modernization, rescue, and product engineering engagements we handle. Names and identifying details are intentionally omitted.
Enterprise Legacy Desktop Modernization
Challenge
10-year-old WinForms ERP application serving 200+ concurrent users, with 900+ stored procedures, zero automated tests, and 3-week deployment cycles. Business growth was blocked by the inability to add features without risk.
Solution
Incremental modernization using the strangler fig pattern. New ASP.NET Core microservices API layer built behind the existing system. React frontend replacing WinForms one module at a time. PostgreSQL migration from SQL Server 2008.
Outcome
Deployment time reduced from 3 weeks to 30 minutes. Test coverage from 0% to 87%. Development velocity increased by 340%.
"DilyaSoft did what three previous vendors said was impossible - they modernized our core system without a single production outage."
- CTO, Enterprise ERP Platform
Automotive CRM Platform
Challenge
Fragmented CRM deployed across 12 dealership groups, built on COM+ components, Access databases, and Excel integration. No scalable API layer, no modern reporting, and a maintenance burden growing faster than the business.
Solution
New domain model designed around automotive sales and service workflows. Modern CRM platform on ASP.NET Core with Angular frontend. Azure Service Bus for inter-service communication. Phased migration with parallel running systems.
Outcome
Unified platform serving all 12 dealership groups. API-first architecture enabling third-party integrations. 60% reduction in support ticket volume.
"They understood our domain from day one. The architecture they designed has given us room to grow for years."
- CEO, Automotive Software Company
Enterprise Form Builder Platform
Challenge
Form builder SaaS with 40,000+ active users experiencing critical performance degradation - 8-second average page load times, frequent timeouts under peak load, GDPR compliance gaps flagged in an enterprise procurement audit.
Solution
Full technical audit. Redis caching strategy. Database query optimization (N+1 elimination, missing indexes). GDPR compliance remediation. CI/CD pipeline rebuild. Playwright end-to-end test suite.
Outcome
Page load time: 8.2s → 1.1s. GDPR compliance achieved, enterprise procurement unblocked. Zero deployment incidents in 14 months post-engagement.
"After working with DilyaSoft, our platform became a product we're proud of instead of one we apologize for."
