Richard Chien

Stdrc developed core features and infrastructure for the risingwavelabs/risingwave and MoonshotAI/kimi-cli repositories, focusing on scalable analytics, AI integration, and developer tooling. They engineered streaming SQL UDFs, OpenAI embedding support, and robust dashboard interfaces using Rust, Python, and TypeScript. Their work included modularizing backend components, optimizing query planning, and implementing end-to-end testing to ensure reliability. In kimi-cli, Stdrc enhanced CLI extensibility, asynchronous workflows, and cross-platform compatibility, introducing features like flowchart-driven prompts and OAuth authentication. The solutions addressed real-world deployment, security, and usability challenges, demonstrating depth in backend architecture, API design, and continuous integration for production-grade systems.

Jan 1, 2026

January 2026 for MoonshotAI/kimi-cli: Shipped core features that improve day-to-day usability and extensibility, while hardening the platform for reliable automation. Features delivered: Soul Skill Slash Commands, Terminal UI (Toad) for kimi term, CLI Info Command with modular CLI structure, and enabling SendDMail in the default agent. Architecture and tooling improvements: wire module re-organization and addition of kimi-sdk to enable external tool integration. These changes, together with version/dependency bumps and documentation updates, lay the groundwork for scalable workflows and faster delivery of new capabilities.

July 2025 monthly summary highlighting feature delivery, minor/no bug activity, and overall impact across RisingWave repos. Delivered two high-value features: (1) In risingwavelabs/risingwave-docs, added an OpenAI embedding SQL function to generate text embeddings and integrated it into a RAG demo, abstracting API key management within SQL (commit 31d37787682e5b13de2509c435dc119651e93847). (2) In risingwavelabs/risingwave, introduced a new Functions dashboard page to view and manage all UDFs, including argument metadata, types, language, and kind (commit aa98e68769c23b6b3ce6c82de96462578f70a3e9). No major bugs reported for this period. Overall, the work accelerates RAG experimentation, improves security/ops by centralizing embedding API usage, and enhances developer productivity through better UDF governance and visibility. Skills demonstrated include SQL UDF development, OpenAI embeddings integration, RAG workflow enablement, API design and security, and dashboard UI/backend integration.
