About this Gig

Get structured ecommerce data at scale, not another manual spreadsheet task.


I build crawlers for public or authorized marketplace data, including category discovery, pagination, product-to-seller mapping, deduplication, checkpoints and CSV/JSON exports.


Documented work includes a finalized Gmarket dataset of 32,820 distinct products and 4,203 sellers, plus a Coupang run across 13 categories with 11,101 product entries and 819 deduplicated sellers. These are past project results, not promised volume or speed for your site.


My experience includes Akamai-protected Coupang environments: detecting access challenges, recording failures and recovering interrupted runs. Access conditions must be tested; I do not promise universal bypass.


BASIC: One-source pilot, up to 500 records and extraction code.

STANDARD: Up to 2 agreed sources, up to 10,000 records, deduplication, resume support and run notes.

PREMIUM: Up to 3 agreed source structures, 50,000 records, resumable batch collection, validation and handover.


Source code is included. Proxy, data-service and hosting fees are separate. Send target URLs, fields and intended volume before ordering so I can confirm feasibility.
