Hello!
I am interested in your project on automated auditing of cash operations.
I have practical experience in Python development with a focus on:
- data processing and analysis (Pandas, CSV/Excel),
- building and optimizing rule-based logic,
- working with texts and regular expressions,
- logging and storing results in SQLite,
- creating UI on Streamlit.
…
I can help with:
- refactoring and structuring existing code,
- improving the logic for determining cash symbols (readability, scalability, case coverage),
- increasing the transparency of ERROR / WARN / OK logic,
- preparing the code for further expansion (including ML, if needed).
I am interested in a part-time/project collaboration format and am also open to long-term work.
I am ready to quickly dive into the MVP and work with real data according to the specifications.
I would be happy to discuss the details and next steps.

Hello. I specialize in Python (Pandas/Regex) and processing large data sets. I have a successful case of parsing and structuring complex tables with over 40,000 rows.
How I can be useful:
Logic and Regex: I will optimize a rule-based system for accurate identification of cash symbols.
Streamlit & SQLite: I have experience building UI for analytical tools and setting up fault-tolerant logging.
Refactoring: I will tidy up the MVP code and package the project in Docker for easy deployment.
…
All advantages and technical stack are in my profile. I am ready to review the technical specifications and start refactoring.

Good day!
I have over 10 years of experience working with Python, I developed a similar system to yours (analyzing Excel reports for accounting, but a different logic judging by the description).
It sounds interesting and not too complicated, considering that the foundation of the system is already implemented on your side.
I am fine with a part-time option, we can communicate in private messages and discuss the next steps.
