I will build custom API integrations between your business systems
Masroor Khalid
About this gig
Struggling to get Shopify, your CRM, POS, or ERP to talk to each other? I build reliable, production-grade integrations that move your data automatically no manual exports or mismatched inventory.
With 20+ years as a backend engineer, I've built real integrations for e-commerce and retail businesses: syncing Shopify orders with courier and CRM systems, connecting POS software to reporting APIs, and consolidating multi-source retail data into a warehouse processing 1M+ records/day.
What I build:
- REST API integrations (Shopify Admin API, Zoho CRM, custom APIs)
- Webhook-based real-time sync with retry/idempotency handling
- Two-way sync between e-commerce, CRM, POS, and ERP systems
- Batch pipelines for large datasets
- Documentation so your team can maintain it after delivery
Stack: Node.js, .NET Core, Python, Oracle, MongoDB, MSSQL, PostgreSQL.
Every project starts with a short discovery chat to map your systems before I write any code, so the solution fits how your business actually works.
Message me with the two systems and the data that needs to move, and I'll tell you honestly if it's a good fit.

FAQ
Which systems can you integrate?
Shopify, WooCommerce, Zoho CRM, Retail Pro Prism and other POS systems, ERPs, and any platform with a REST API or webhooks. Send me your two systems and I'll confirm compatibility before you order.
Do you need access to our systems?
Yes, typically API keys or OAuth credentials with least-privilege access. I'll walk you through exactly what's needed and you can revoke access anytime after delivery.
Can you handle high volumes of data?
Yes — I've built pipelines processing 1M+ records a day and a data warehouse consolidating sales data across 70 retail stores. Volume and performance are things I plan for up front
What if our systems don't have an API?
Message me first with details. Some platforms need custom scraping or file-based sync (CSV/FTP) instead of an API — I can usually still build a reliable solution.
Will I get documentation after delivery?
Yes, every integration ships with clear documentation of the data flow, credentials setup, and how to troubleshoot common issues so your team isn't dependent on me.
