2024.7 - 2024.9 During this period, I focused on the development of the typesetting engine, editor functionality, and scheme interpreter for Liii STEM and its open-source counterpart Mogan STEM .

• Developed the https://github.com/XmacsLabs/goldfish and standard libraries, including the packrat parser, REPL, and markdown tokenizer, which serve as the scripting foundation for the typesetting software.
• Implemented a streaming LLM renderer for real-time rendering of LLM output within the typesetting environment.

These tasks required deep integration between the interpreter, editor, and rendering pipeline, as well as designing extensible APIs for scripting and automation.

2022.7 - 2023.7 During the internship, I was mainly responsible for the backend development and SDK writing of flows.network .

Stack 2.1.  flows.network [flows.network]

• https://flows.network/
• GitHub

Automate all your software tasks. Create GitOps, ChatOps, and DevOps automations using serverless functions!

Serverless platform using WasmEdge as runtime. Developed by Second State .

For backend server development work, I connect it with different platforms like GitHub, Telegram. I would read and study their documentation and then write the authentication and communicating logic. After encapsulation, it is written as a server according to the api requirements of flows.network .

• GitHub Server
• Telegram Server

I also need to write SDK in Rust for users of flows.network so that they can interact with the servers.

Since the environment in which flows.network runs the program is WasmEdge , the targets of the sdk are all WASI. I need to make a lot of trade-offs and workarounds specific to the WASI target.

• Notion SDK
• Discord SDK

Stack 2.2.  WasmEdge [WasmEdge]

• https://wasmedge.org/
• GitHub

WasmEdge is a lightweight, high-performance, and extensible WebAssembly runtime for cloud native, edge, and decentralized applications. It powers serverless apps, embedded functions, microservices, smart contracts, and IoT devices.

The fastest WASM VM written in C++. Developed by Second State .

2023.9 - 2024.7 I do a lot of testing and development on RisingWave .

Stack.  RisingWave [RisingWave]

• GitHub

RisingWave is a Postgres-compatible streaming database engineered to provide the simplest and most cost-efficient approach for processing, analyzing, and managing real-time event streaming data.

I need to test the sink/source connection between RisingWave and various connectors, and need to write connector e2e tests for CI.

• ci: add dynamodb integration test
• ci: add pubsub integration test
• test: add integration test for mindsdb

I also wrote and fixed some sink/source connectors to enable efficient data communication with RisingWave without losing data.

• feat(connector): add DynamoDB sink
• feat(sink): add Google Pub/Sub support

In addition to connector-related work, I will also do many database kernel-related work, such as supporting a certain SQL statement, adding a certain built-in function, adding internal tables, etc.

• feat(telemetry): add streaming_job_count to meta telemetry report
• feat(expr): implement <expr> [ NOT ] SIMILAR TO <pat> [ ESCAPE <esc_text> ]
• feat: support convert_from/convert_to function that only support UTF8 encoding
• feat: add comment on clause support

2024.11.10 - now I develop MoonBit 's standard library and third-party libraries as needed.

• encoding
