Social News Feed System

We built a News Feed system for a social network with a few million daily active users. 该系统是社交网络的一个子产品, 我们用数据驱动的思维方式来设计系统. We first formed the metrics for a successful News Feed and then implemented the system to achieve the target KPI.

Technically the system was designed using microservices best practices and strictly followed the 12-factor app methodology. We used Kafka for streaming data and Airflow for batching data for the machine learning service. The heart of the News Feed system was a hybrid recommendation engine in which we tried to create several different models for different customer segments. We also made an experimentation service to set up an experiment to improve the model quickly.

底层技术栈包括:
•架构微服务
•Python与Flask的所有api
•Kafka和气流数据流和批处理
•数据库为Cassandra和MongoDB
•用于容器化和部署的Docker和GKE
•用于代码修订控制和CI/CD的GitLab和ArgoCD

Mobile eWallet

我们在Android和IOS上创建了一个移动电子钱包, aiming to make the money transfer experience as simple and as easy as possible. The eWallet facilitated direct money top-ups and withdrawals from a bank account via a host-to-host integration with the bank. It also supported P2P money transfers via a phone number and social network and product/service purchases from third-party eCommerce vendors.

Underlying Technologies:
•架构微服务
•Java + Spring框架，Python + Django服务
• MySQL for the database
•用于服务间通信的Protobuf
•OAuth 2用于用户认证和授权
• Docker for containerization
•GitLab用于代码修订控制和CI/CD

Financial Chatbot Platform

我们帮助一家银行建立了一个金融服务的聊天机器人平台. 它是银行与客户之间的另一个沟通渠道. 用户可以查询余额, transfer money, create a savings account, and buy value-added services from an instant-messaging app like Facebook Messenger.

聊天机器人平台的核心, there's a message queue aiming to stream users' chat messages to the rule-based processors and stream the replies to users. On top of the core, 适配器使平台能够与多个服务集成, including Facebook Messenger, Zalo, and more.

采用微服务架构和发布/订阅模式, the platform could be easily scaled up to process a few million messages per second.
