Project details
I will clean, transform, and validate CSV or Excel data with Python. I review your source files and expected output, define clear transformation rules, handle missing or inconsistent values, and deliver a repeatable workflow with readable code and concise notes. This service fits reporting cleanup, imports, migrations, recurring spreadsheets, and small data pipelines. I confirm scope and edge cases first, then process representative samples, validate results, and explain how to run the workflow again. Please use placeholders or a secure handoff for credentials and never send passwords or API keys. I personally review the output before handoff so the result is understandable and maintainable.

About D
Full-Stack Developer | Python, React, APIs & AI
Guangzhou, China - 7:41 pm local time
I can build or improve:
• Python backends, FastAPI services, REST APIs, webhooks, authentication, validation, and error handling
• React/TypeScript/JavaScript interfaces, responsive pages, dashboards, admin panels, forms, tables, and reusable components
• Automation tools, Python CLI utilities, web scraping, CSV/Excel processing, ETL, data cleanup, and scheduled workflows
• Third-party API integrations, data pipelines, Docker-based local setups, packaging, and deployment preparation
• Bug fixes, refactoring, regression tests with pytest, performance troubleshooting, and practical security hardening
I can work from a clear specification, a backlog, or an unfamiliar codebase. I focus on identifying the real problem, implementing a focused solution, and leaving code that another developer can run and maintain. For larger builds, I provide clear milestones, surface risks early, and keep communication concise and actionable.
The projects on my profile demonstrate Python automation, Dockerization, backend fixes with focused tests, and code reliability/security reviews. I also publish clearly labeled personal contributions and forks based on MIT/Apache-licensed open-source projects. I preserve original attribution and licensing, and describe only the changes I personally made.
I use AI tools when they improve research or debugging speed, but I personally review, test, and refine the final implementation. You get readable code, practical documentation, and an accountable delivery process—not just a quick patch.
If you need someone who can independently turn an idea, workflow, or existing codebase into a usable product, send me the requirements and I’ll propose the shortest path to a solid result.
