What I'm looking for

I’m looking for a backend role where I can build production-grade ASP.NET Core APIs with strong security, clean architecture, and real CI/CD ownership—ideally using AWS. I value teams that ship, test, and iterate fast.

I’m a backend developer focused on building production-deployed REST APIs that are clean, testable, and security-first. I enjoy turning complex requirements into well-structured architectures using clear boundaries and dependable tooling.

In my School Management System project, I architected a Clean Architecture solution across 5 dedicated C# projects (API, Core, Domain, Infrastructure, Service) with an xUnit test project and strict inward dependency rules. I implemented CQRS with MediatR, FluentValidation pipeline behaviors, and AutoMapper projections to keep business logic fully decoupled and easy to test.

I also brought reliability and operations into the design by deploying to AWS Elastic Beanstalk with automated CI/CD on every git push via CodeBuild. I integrated multi-layer authorization (RBAC, claims-based policies, custom action filters) and secure data handling using AES-256 column encryption, alongside JWT with refresh token rotation and replay protection.

Beyond that, I built an E-Commerce REST API with EF Core code-first migrations, JWT Bearer auth, refresh token rotation, role-based access for Admin/Customer, and a SignalR Hub for real-time stock updates. I complement my backend work with a front-end e-commerce platform (HTML5/CSS3/JavaScript ES6+), and I’ve strengthened my cloud/deployment foundation through DevOps training configuring AWS (EC2, S3, IAM, VPC) and GitHub Actions CI/CD.
