Data Collection (Web Crawling) + Dashboard/Reporting System Development

We employ headless browsers (Puppeteer/Playwright), rotating proxies, CAPTCHA-solving services, and session-based login automation. We design resilient pipelines with retry logic and fallback strategies so data collection continues even when sites change their anti-bot measures. For sites with strong protections, we assess feasibility upfront during the scoping phase.

Yes. We integrate directly with Google Sheets API so collected data is auto-populated in real time or on a schedule. You can also set up change-detection alerts that notify your Slack or email when specific data changes. Historical data is automatically archived in separate sheets.

Collection frequency is fully customizable: real-time (every few minutes), hourly, daily, or weekly. We discuss your business needs to determine the optimal schedule, balancing data freshness with server load and cost efficiency. Cron-based scheduling and event-driven triggers are both supported.

Our pipeline includes automated DOM monitoring that detects structural changes and triggers alerts. When a change is detected, our team applies an emergency patch — typically within 4 business hours under our maintenance SLA. We also design selectors with resilience in mind to minimize breakage from minor changes.

We implement multi-layer quality management: deduplication with unique key matching, validation rules per field, missing-data alerts, anomaly detection, and automated QA checks with configurable thresholds. Data cleansing stages are built into the pipeline and quality metrics are reported in the dashboard.

Upon full payment, all source code and intellectual property rights are transferred to you. You receive the complete codebase, documentation, deployment guides, and Git repository. We do not retain any copies or usage rights after the transfer.

Yes. We can deploy the entire system on your internal infrastructure using Docker containers or standalone executables, with no external network dependency. This is especially suitable for companies with strict data sovereignty requirements or that handle sensitive competitive intelligence.

We provide 1 month of free warranty after delivery. After that, monthly maintenance plans are available, covering monitoring, site-change patches, bug fixes, and performance tuning. SLA-based contracts guarantee response times: critical issues within 4 hours, general requests within 1-2 business days. Pricing depends on system complexity and monitoring scope.

Quotes are based on: number of target sites, data complexity (login/CAPTCHA/dynamic rendering), collection frequency, output format (spreadsheet vs dashboard vs API), data volume, infrastructure requirements (cloud vs on-premise), and maintenance scope.

Web crawling for publicly available data is generally legal. We strictly follow robots.txt guidelines, avoid overloading target servers, and do not collect personal information without consent. We advise clients on legal boundaries and design systems to comply with the target site's terms of service and relevant data protection regulations (including Korea's Personal Information Protection Act).
