High Frequency Trading Experiments
My experiment into how I would begin to think about a high frequency trading platform. The goal of this experiment is to maintain strict account-level consistency and transaction ordering but with high throughput. In terms of CAP theorem, I am prioritizing consistency and partition tolerance over availability. This system utilizes Redis consumer groups (which could easily scale to a Kakfa-level system) and account-level locks to maintain consistency and ordering.
Rusty Chat
An experiment in creating a high performance, websockets chat service built with Rust and Actix/Actix-Web with an SQLite database and custom session management. Digging deeper into the actor model. Currently containerized with docker and served on digital ocean with an nginx reverse proxy.
Rabin Karp - WASM-pack
This is a rust implementation of the Rabin-Karp string searching algorithm wrapped into a neat npm package for use in node environments. Given a substring pattern and a larger string sample, it will find all indexes where a valid substring match exists. The efficiency of the algorithm is that it uses a rolling hash to be able to function in linear time. By my rudimentary benchmarks, it runs about 4 to 7 times faster than a pure JS algorithm.
The YLC CMS
A custom CMS built using react-static, NetlifyCMS and distributed over Netlify for a neat, git-based system.
Free Source
A RESTful server that records freediving training and performance information. Built with NestJS, GraphQL, PostgreSQL, TypeORM, PassportJS, and Redis. Currently building out a React Native app as well as web front-end.
Solana Dutch Auction
A dutch auction program built with Anchor for the Solana blockchain. Programs on the blockchain are stateless, small, and secure.
Tensor Sentence Compare
A node implementation of TensorFlow's Universal Sentence Encoder that compares the similarity of a sentence and a response based on dimensional embeddings. A monorepo with react as a front-end.
Gravity Ball V2
A physics-based game made with BabylonJS. Don't fall off the platform!
