I will integrate business systems and build custom API connections

Almost any system with an API, database access, or file export capability. This includes CRMs (Salesforce, HubSpot), accounting software (QuickBooks, Xero), e-commerce (Shopify, WooCommerce), ERPs, databases, and custom applications.

Depending on your package: (1) Scheduled sync runs at intervals you define (hourly, daily), (2) Near real-time polls for changes every few minutes, (3) Real-time uses webhooks or change detection for instant updates. I'll recommend the best approach based on your data volume and business needs.

I have several approaches for systems without APIs: direct database connections, file-based integration (CSV/Excel exports), screen scraping/RPA for web applications, or building a custom middleware layer. Legacy system integration is one of my specialties.

I build comprehensive error handling including: conflict resolution rules (which system wins), automatic retry logic, error logging, and alerting. For critical integrations, I can set up a monitoring dashboard so you see sync status in real-time.

I design integrations to be resilient to minor API changes. Major changes may require updates, which is why I recommend the extended support option for production-critical integrations. I also document everything so any developer can maintain it.
