+# Imageboard Clean Architecture Back-End
+
+*This is the part of project which includes back-end and mobile client.* 
+
+**Also check:**
+`Android Compose Clean Architecture Client (in progress)`
+
+## Project description:
+  **Simple anonymous imageboard which allows to create threads, posts and reply to users by quoting their posts.**
+
+## Techs:
+- **Golang**
+- **MongoDB**
+- **gRPC**
+- **Protobuf**
+- **Docker**
+- **Yaml**
+
+### Thoughts:
+**Well, I use `Golang` when I need to get simple and obvious product. I really like it, because I can create what I need without tons of libs and avoiding extra dependencies. Also Golang is great to fit with *Clean Architecture* because of abstraction through composition. I think that the stucture of this project is pretty good and I will use it again.**
+
+**I like `MongoDB` because it's flexible and not very complicated to compose effective database query inside repository. Also it doesn't need to create a special abstraction on top of database methods which is definitely an advantage.**
+
+**What about `gRPC`? I think that it's good to be used as a CRUD alternative to REST, but I would prefer Web Sockets for real-time (I mean "actually real-time", e.g. chatting) operations to avoid polling strategy, although gRPC is good for it, but I just think that each task needs it's own tool.**
+
+**`Protobuf` is good to use for crossplatform products, but it's a bit tricky to set up the projects, because the implementations are different (especially in the case of the JVM). Sometimes it matters.**
+
+**`Docker` is simply the best way to deploy an application, especially if you want to use database replication (which is really painful without it).**
+
+**`Yaml` is just the simple way to create separate config file.**
