Provide target categories, collections, or regions. We design the extraction schema together.
We configure Scrapy / Playwright crawlers, proxy rotation, session management, and CAPTCHA handling for chowsangsang.com.
Schema validation, null-rate checks, price-outlier detection, and sample data before full launch.
JSON / CSV / Parquet pushed to your S3 bucket, BigQuery dataset, or Snowflake stage on agreed cadence.
Jewellery retailers deploy strict geo-fencing and dynamic pricing widgets. Here is how we stay resilient - and why teams choose managed infrastructure over DIY.
Retailers block automated traffic to protect pricing data. Our crawlers use residential ISP proxies with realistic browser fingerprints, randomised request timing, and full cookie session management.
Live gold pricing and inventory statuses are heavily JavaScript-rendered. We run full Playwright browser sessions with JavaScript execution to capture data that headless HTTP clients miss entirely.
Chow Sang Sang displays different prices and inventory based on user location. We route requests through region-specific proxy pools to capture accurate data for Hong Kong, Mainland China, or Taiwan.
E-commerce platforms change their DOM structure frequently during promotions. Our selector strategy uses multiple fallback chains per field so a layout change does not break your data pipeline.
For large jewellery catalogues, we maintain a hash index of last-seen values. Subsequent runs only push diffs, reducing compute cost and downstream processing load.
Jewellery brands monitor daily gold rates, labour charges, and diamond pricing to adjust their own retail strategies.
Analysts track regional price differences in 999.9 gold products between Hong Kong and Mainland China.
Data science teams use 4Cs and GIA certification data to build automated diamond valuation algorithms.
Merchandisers track new collection launches, category depth, and stock availability to identify market trends.
Market researchers analyse pricing parity and product availability across different Asian markets.
Secondary market platforms verify product weights, materials, and collection details against official catalogue data.
"Chow Sang Sang provides a real-time pulse on Asian gold and diamond markets, but extracting that intelligence requires navigating dynamic pricing and strict geo-fencing."
Most teams underestimate the investment required: reliable jewellery scraping requires geo-targeted residential proxies, full JavaScript rendering for live widgets, and daily selector maintenance. DataFlirt absorbs that complexity so your engineers can focus on the analysis, not the infrastructure.
Everything supported by our chowsangsang.com scraper — rendered SPA elements, auth walls, rate-limit evasion and beyond.
Open-source tooling on proven cloud infra — no vendor lock-in, full observability.
Scrapy handles crawl orchestration, deduplication, and retry logic. Playwright handles JavaScript rendering, cookie sessions, and interaction flows. Combined via scrapy-playwright middleware.
We maintain pools of residential ISP proxies across HK/CN/TW regions. Rotation happens per-request with sticky sessions where required. IP score monitoring prevents blacklisted pool contamination.
Pipelines run on AWS Lambda and ECS. Airflow handles scheduling, dependency management, and SLA alerting. All state stored in managed Postgres.
Data delivered to where your team already works — no new tooling required.
