Senior Golang Developer
Hi! My name is Andrey, and I am the team lead at Chatfuel. I'm in charge of the backend in the company, and now I'm responsible for transitioning from monolith on Kotlin to microservice architecture on Go.
In early 2024, we started developing a new product while transitioning our old monolithic Kotlin application to a microservices architecture on Go. Part of the new product is already successfully running in production on the new stack. We are looking for a technical specialist to help us further develop and scale our new platform.

- Take full responsibility for the invention, development, and production, and following support of several large parts of the application.
- Independently evaluate deadlines and risks, clarify requirements.
- Work in a team: it is essential to hear colleagues, negotiate, present your solutions, and give constructive feedback.

Our core systems:
