An enterprise-grade core banking system built on a modern microservices architecture using .NET and C#.
The Problem
Legacy monolithic banking platforms struggle with single points of failure, long deployment cycles, and the inability to scale individual services during peak transaction loads — directly impacting transaction throughput and customer experience.
The Solution
Decomposed the monolith into independently deployable microservices communicating via gRPC for low-latency inter-service calls, with a YARP reverse-proxy gateway handling routing, load balancing, and rate limiting at the edge.
Why This Stack
.NET 10 was chosen for its high-throughput Kestrel server and native AOT compilation support. gRPC was selected over REST for internal communication to reduce serialization overhead. PostgreSQL provides ACID-compliant transaction safety, and Docker ensures environment parity from development to production.
A full-featured e-commerce backend providing secure REST APIs for product catalog, user management, and order processing.
The Problem
Small-to-mid-size merchants need a reliable backend that handles secure user authentication, inventory management, and order workflows without the overhead and vendor lock-in of large SaaS platforms.
The Solution
Built a clean, layered REST API with stateless JWT authentication, enabling horizontal scaling behind a load balancer. Structured the codebase with repository and service patterns so business logic remains testable and independent of infrastructure concerns.
Why This Stack
ASP.NET Core was chosen for its built-in dependency injection and middleware pipeline, which simplifies auth, logging, and error handling. JWT provides stateless authentication that scales without session-store bottlenecks. PostgreSQL delivers relational integrity for order-inventory relationships, and Docker containerization guarantees consistent deployments.
