Message

At ONEPROPELLER, I design and implement .NET Core REST APIs and microservices, including subscription payment flows for processing, renewals, cancellations, and failure recovery.

I’ve also built resilient messaging with RabbitMQ and the Outbox pattern, and developed a multi-origin invoice processing microservice at MISTRAL using .NET Core, AWS, PostgreSQL, and React.js. I’m an AWS Certified Solutions Architect – Associate focused on backend development and cloud technologies.
