About muki
API Integration Specialist | Shopify, Xero & Automation Expert
Akure, Nigeria - 8:34 am local time
I specialize in third‑party API integration: creating custom “bridges” between applications so they can talk to each other seamlessly via RESTful APIs / web services, JSON, webhooks, and robust data pipelineseliminating redundant task lists, reducing error rates, and unlocking workflows you didn’t think were possible.
My Core Expertise:
• E-commerce & Logistics: Shopify (including multi-store setups), WooCommerce, Amazon SP-API, eBay, ShipStation, Shippo, and warehouse/3PL systems
• Communication and CRM: Twilio (SMS/Voice/WhatsApp), SendGrid, HubSpot, Salesforce, Zoho
• Finance & Operations: Stripe, QuickBooks, Xero (API/reports/exports), inventory management APIs
• Data & Automation: Custom REST API integration, CSV/XML import/export pipelines, workflow automation (Zapier/Make com alternatives), API troubleshooting/debugging, and clean handoffs between systems
What I Deliver:
🔹 Data Sync You Can Count On (reliability first): Orders, customers, inventory, tracking, and payments synced across store → ERP/CRM in near real time with clear handling for rate limits, pagination, retries, and error logging.
🔹 Custom Automation (end-to-end execution): Auto-generate shipping labels, post‑purchase SMS notifications, routing/trigger logic, and support automations that keep teams out of inbox chaos.
🔹 Scalable Backends: Robust Node js / React js / Python services built for high-volume API calls, with clean, maintainable, well-documented code, strong observability (logs), and practical performance-minded implementation.
🔹 Documentation & Maintainability: You get clean code, well-defined setup guides, and a system your team can run long-term (I work comfortably with Git and structured delivery/checklists inside existing codebases).
I’m not just tying APIs together I get business flows. What I want is to create an integration that seamlessly runs for you in the background like a workhorse, but without making a single PFFFTTT noise!
