About this gig
LIMITED TIME PROMO: I offer discounted rates for my first 5 clients while building my Fiverr portfolio. Get professional performance engineering at a fraction of the cost before rates increase!
Is your Python code too slow? I specialize in speeding up Python scripts by finding bottlenecks and rewriting critical functions in high-performance C++. Using wrappers like PyBind11 or Cython, I integrate optimized code directly into your project, preserving your workflow.
Services:
Profiling: Identify slow code.
C++ Integration: Rewrite heavy logic for 5x100x speedups.
Refactoring: Clean, efficient Python code.
Benchmarks: Before/after performance reports.
GitHub-ready: Clean, structured repositories.
From small scripts to complex appsdata pipelines, simulations, AI, or trading toolsI deliver reliable, high-performance solutions.
Why choose me: Python + C++ expertise, clean, maintainable code, fast communication, and focus on your goals.

I am a results-driven ML engineer recognized for building end-to-end predictive systems. I specialize in designing, deploying, and scaling AI solutions that directly impact core operations. I bring a “full-stack” perspective and lead with metrics.
Beyond MLOps, I have solid engineering expertise in Python and C++. I use Python to develop data pipelines, training workflows, and production APIs, while C++ helps me build optimized, high‑performance modules when speed and efficiency matter
FAQ
What type of Python projects can you optimize?
I can optimize anything from small scripts to medium projects and even complex applications that need critical functions accelerated with C++.
How much faster will my code run?
Depending on the project, optimized functions can run 5–50x faster than your original Python code.
Do I need to know C++ to use the optimized code?
No. I provide a Python wrapper so you can call the optimized functions just like any regular Python function.
Do I need to know Python to use the optimized code?
No. I can integrate the C++ wrapper directly into your Python code, so it works out-of-the-box. Basic Python knowledge helps if you want to call functions or tweak them, but no deep C++ or complex integration is needed.
What do you need from me to start?
Please provide your Python code, a clear description of the bottleneck functions, and any input/output examples if possible.
Can you handle complex projects with multiple functions?
Yes. For larger projects, I can optimize multiple bottlenecks and provide a clean, maintainable Python+C++ integration.
Do you offer revisions if something doesn’t work?
Yes, each package includes a set number of revisions to ensure the optimized code works correctly in your workflow.
Do you provide benchmarks or proof of speed improvements?
Yes. For Standard and Premium packages, I include before/after execution times to demonstrate the performance gains.
Can you optimize code in other languages besides Python?
Primarily I specialize in Python performance, but I can work with C/C++ or other languages on request.
