Real-time transaction analytics platform for 2M+ daily users. Built with React, .NET Core APIs, and PostgreSQL with Redis caching for sub-50ms response times.
NexaPay needed to migrate from a monolithic PHP application to a modern, scalable microservices architecture. The old system was causing frequent outages during peak trading hours. Sironik led a phased migration over 8 months — rebuilding the data layer first, then migrating the API surface, and finally the frontend. The result was a 340% improvement in response times and zero planned downtime during the cutover.
"Sironik's engineering team transformed our legacy systems into a modern, scalable platform. The migration was seamless, and performance improved by 340%."
