BACKEND & DATA AUTOMATION / BY KHANH

Every order.
Every payment.
Accounted for.

When your order export and payment export disagree, find the exact records to investigate. Clearfold demonstrates a repeatable workflow with validation, exception review and a clear audit trail.

01 / THE WORKFLOW

From two files to an explainable result.

01

Bring the exports

Upload two UTF-8 CSV files. Map your columns and agree on the cutoff date, fees, refunds and matching rules.

02

Inspect the exceptions

Find missing, short, excess and unmatched payments. Split payments and negative adjustments are summed by order.

03

Leave a record

Add review notes, reopen a case and export CSV or JSON evidence. Original source amounts stay unchanged.

WORK WITH KHANH

Have a repetitive workflow
or an unreliable API?

I work on Java / Spring Boot backends, Python data processing, API integrations and AWS. My professional background includes banking, insurance and logistics software.

A useful first project has a specific input, expected output and acceptance check. Share the issue and a sanitized example through Upwork; we can define a small scope before implementation.

Good starting points

  • A reproducible Java API bug with regression tests
  • One recurring CSV cleanup or reconciliation workflow
  • A bounded API integration with retries and error reporting

What this demo does — and what it needs.

Interactive demo: Try CSV import, column mapping, filters, review notes, audit history and exports in English or Vietnamese. Files are processed in your browser. Demo batches stay in this tab’s session storage; this is not a shared online database. Use synthetic data and export your work before closing the tab.

Before using real data: agree source definitions and validate results with the person responsible for reconciliation. Direct Shopify, Shopee and bank connectors are not included. The interactive demo requires no login and sends no imported file contents to a server.
