A web-based interface to an end-to-end encrypted cloud storage application. This project was particularly interesting, as due to the nature of zero-knowledge encryption, complex functionality, which is usually handled in the back end must be handled client-side. This creates many unique front-end engineering challenges, which must be solved using various browser APIs such as Web Worker, WASM, and Web Crypto.

It also increased the complexity of the front end and taught me a lot about how to make a large front-end codebase well-organized and scalable.

A web app for the programming and live control of automated chemistry systems. The app allows chemists to write their procedures in natural language and run them on automated chemistry systems without writing any code. The back end consists of a Python GraphQL API, with Socket.IO facilitating real-time communication for live control and monitoring of chemistry robots. The front end consists of a procedure editor, a graph editor, and a live control and sensor monitoring mode.

I designed and created a custom programming language for automated chemistry systems. The language is expressed in the language of chemistry, without any assumptions about how the chemistry will be carried out. The software then compiles this representation into instructions for a specific automated chemistry robot.

The language is built using a component-based architecture, similar to React, where each component is a set of chemistry instructions. These are combined hierarchically to create high-level operations which the user can easily program without understanding the low-level implementation.
