PayNexa
PayNexa is a fintech payment platform built as .NET 10 microservices (Customer, Authentication, Payment, Transaction, Notification) behind a YARP API gateway. Each service follows Clean Architecture, DDD and CQRS. Writes go to SQL Server, reads come from MongoDB read models, and Redis is the cache. Events flow to Kafka through a transactional outbox. Every request is logged end to end with Serilog, Seq and OpenTelemetry under one correlation id, with personal data masked. The whole stack runs in Docker.
