Right now the most urgent need is to deliver new functionality, and nearly all of that work sits squarely on the back end. Your first assignments will centre on extending our microservice architecture and exposing new, well-documented APIs. You’ll be writing C#, containerising services, wiring events through RabbitMQ, and persisting data in PostgreSQL—then shipping the code straight into production. I pay $6/hour for hands-on development only; time spent reading code, researching, or experimenting is on the freelancer.

I’m putting together a production-ready microservice architecture written in Go. The heart of the work is a robust queuing layer—think Kafka or RabbitMQ—so messages flow reliably between services. I’ll share the exact flow charts and edge-cases once we start, but the goal is a clean, well-tested service that can scale without drama. For the user-facing side I’d like the front-end handled in react as well, keeping the stack uniform for faster compilation pipelines and simpler deployments. Data lands in a SQL store, specifically MySQL, so the schema, migrations, and query layer need to follow best practices and remain easy to extend. Beyond the initial build I’ll need ongoing pairing: troubleshooting, adding new endpoints, tightening performance, ...
