High-performance Rust systems, quant & Python (PyO3) toolingStephen via Replit
I build performance-critical systems in Rust: backend services, algorithmic and quantitative engines, and native and CLI tooling. My work includes a multi-crate genetic-programming trading platform, a from-scratch concurrent in-memory cache server, game-theoretic and deep-learning engines, and a published open-source Rust CLI on crates.io.
I also bridge Rust and Python with PyO3, giving you Rust-level speed behind a clean
Python API with full type hints. That is ideal for accelerating data pipelines (Polars, NumPy) without leaving your Python stack. I work architecture-first (clean and hexagonal layering, domain-split Cargo workspaces), with strict linting, unsafe-denied code, real test coverage, and thorough documentation. If correctness and speed are the point, this is what I do with rigor.
What's included
- Rust services and APIs (Axum, Tokio)
- Algorithmic and quantitative systems
- Rust-and-Python (PyO3) extensions and Polars plugins
- Concurrency and performance optimization
- CLI tools and native utilities
- WASM and Dioxus front-ends where useful
Ideal for: teams who need a piece that must be fast, correct, and memory-tight, or who want to accelerate a Python codebase with native Rust.
