【⭐⭐⭐⭐⭐】FullStack-BigData-App-Pokemoney

Pokemoney is a personal finance app supporting offline and online modes with multi-device synchronization. Built with Flutter and SQLite on the frontend, and a robust backend stack, it enables scalable, distributed data processing.
The system is built on a modern lakehouse architecture with a microservice-based real-time data pipeline, combining Kafka, Spark, HDFS, Hive, and NiFi for scalable data ingestion, processing, and warehousing. It also integrates a polyglot backend with Redis, MySQL, and HBase, orchestrated via Dubbo, Nacos, and Docker, supporting Dubbo, Triple(gRPC like), RESTful and GraphQL APIs.
Due to the budge limit, I bought two small servers and my own laptop to deploy the services separately.

Pokemoney记账软件

项目介绍

Pokemoney = poke + money = pocket + money = 宝可梦 :)

An accounting software that supports both offline and online modes, as well as multi-device login. Each device can switch between accounts, create multiple funding sources, different ledgers, and categorized directories.

The backend supports a large number of users, can be deployed via Docker, connects to a big data platform, and allows the creation of a personal data warehouse.

可离线+联网并且多设备登录的记账软件，一个设备可切换账户，创建多个资金源和不同账本以及不同目录。

后台支持大量用户，同时docker搭建并连接大数据平台，以及创建自己的数据仓库。
