What I'm looking for

I’m looking to build reliable, secure fintech and web systems—enhancing APIs, reporting, and messaging—while working with clients and teams in a collaborative environment that values adaptability and practical problem-solving.

I’m a Software Engineer who enjoys solving practical problems with a structured, organized approach. I build and enhance applications and reporting features using ReactJS, AngularJS, Blazor, and .NET (dotnet, dotnetcore), while leveraging AWS services like S3, Elasticsearch, and EventBridge.

In fintech and payment work, I’ve migrated legacy systems to Dotnet 8, built payment and API integrations, and implemented security across APIs using RSA key-based digital signatures, encryption, and JWT-based authentication. I also focus on reliability through unit tests, robust logging with Serilog, and message-based architecture using RabbitMQ and MassTransit, backed by OOPS and SOLID principles.
