Random Data Generator for arbitrary data types▲5
Datasino is a command line tool that can come handy when load testing a service or database. Give it a data schema (many compound types supported, including recursive types), an encoding (JSON, CSV or ClickHouse) and a target (a file or a Kafka partition) and a data rate and it will generate a reasonably optimized (native code) random data source. See the top of the README for some examples. If you have any ideas on how to extend this tool so that it's useful to more people, please let me know.

Typical is TypeScript with type-safety at runtime▲8
Spent a week in the break building a pre-compiler that brings type safety to runtime. Still pretty early, but generally does what it says. Looking for feedback, code that breaks it (check out the playground), ideas etc.

KubernetesJS – Fully-Typed, Zero-Dependency Client for Kubernetes▲5
I built KubernetesJS because I was frustrated with the state of Kubernetes tooling for TypeScript developers. Most existing clients, like kubernetes-client, were last updated five years ago and rely on generating clients at runtime from Swagger specs. That approach works, but it lacks strong typing, good auto-complete, and tends to feel brittle in larger projects. KubernetesJS also uses the Kubernetes Swagger schema, but instead of generating clients at runtime, it generates fully-typed static TypeScript code at build time. That means you get excellent TypeScript support, predictable APIs,…

API to convert users' plaintext input into functions your site can run▲7
Created a way for anyone to define the data types associated with their SaaS/website such that we can parse plaintext user requests into function calls that the backend can handle. For example. User types “Rename all my documents in the ‘Memos’ folder to follow the pattern “[Department] Memo: [Date]”, our API yields JSON with the IDs of functions to be called and their parameters.
