You will get fix or improve your Python script
Project details
I help identify, debug, and fix complex Python issues in existing codebases.
If your script crashes, runs slowly, produces incorrect results, or became
hard to maintain — I will analyze the root cause and provide a clean, stable solution.
I work with production code, legacy projects, automation scripts, APIs,
data processing pipelines, and performance-critical Python applications.
My approach includes deep debugging, safe refactoring, performance optimization,
and clear explanations of what was fixed and why.
You will receive clean, readable code, improved stability, and practical
recommendations to prevent similar issues in the future.

About Viacheslav
Python Developer | Automation, Data Pipelines, Flask APIs
Brooklyn, United States - 7:01 am local time
My core focus is building reliable Python solutions that save time, reduce errors, and scale smoothly. I work with automation scripts, data processing pipelines, REST APIs, and Flask-based backend services. I also help clients fix, refactor, and optimize existing Python code when performance, stability, or maintainability becomes an issue.
Over the years, I have developed:
• Python automation scripts for data processing, CSV/Excel handling, and API integrations
• Flask REST APIs and webhook-based services
• Trading bots and algorithmic trading logic
• Debugging and refactoring of legacy or poorly structured Python code
• Performance optimizations and security improvements
I pay close attention to clean architecture, readable code, and predictable behavior in production. My goal is not just to “make it work”, but to deliver solutions that are easy to maintain and extend in the future.
If you need:
• Python bug fixes or deep debugging
• Automation scripts or custom tools
• Flask APIs or backend logic
• Code optimization and refactoring
—I can help you get it done efficiently and correctly.
