You will get a speed up to your Python app by 50x using Rust extensions (PyO3)
Project details
Love Python but hate the speed? I’ll build Rust-accelerated extensions for your heaviest functions — no rewrites needed, just pure speed.
You don’t need to abandon Python to get native performance. I build Rust modules using PyO3 that integrate directly into your Python environment — offering 10x–100x speedups for data processing, calculations, or I/O-heavy tasks.
Instead of full rewrites, I target the 5% of your code that causes 95% of the slowdown and replace it with compiled, memory-safe Rust.
My Process:
Benchmark your script to locate slow sections.
Write high-performance Rust extensions.
Integrate via PyO3 bindings and provide example usage.
Use Cases:
Scientific calculations, data pipelines, or ML preprocessing
API response bottlenecks
Legacy scripts that crash under load

About John
Sr. Systems Architect | Py/Rust/C++ | AI/ML | Zero-Backend Solutions
Tampa, United States - 7:34 pm local time
As a Sr. Systems Architect, Data Scientist, and Full-Stack Engineer, I bring a unique blend of expertise in high-performance computing, memory optimization, and secure infrastructure. I design and implement systems that not only meet stringent technical requirements but also drive commercial success.
Why I’m Different:
While many developers integrate APIs, I build solutions from First Principles—addressing challenges like:
Running advanced 7B LLMs on edge devices
Securing networks against zero-day vulnerabilities
Creating crash-proof Rust backends
Delivering seamless full-stack applications
My background, including the Teixido-Boreal Paradigm in deep-tech research, ensures I apply scientific rigor to all stages of software development and system architecture.
