I will integrate apis and build custom microservices or backend automations


About this gig
Your tools should talk to each other but they don't. I fix that.
I build custom API integrations and backend automations that connect your apps, sync your data, and eliminate manual work between systems.
What I connect:
- CRMs: HubSpot, Salesforce, Pipedrive, Zoho
- E-commerce: Shopify, WooCommerce, Prestashop
- Communication: Slack, WhatsApp, Telegram, Gmail
- Databases: PostgreSQL, MySQL, Airtable, Notion
- Any REST API, GraphQL, or webhook
What you get:
- Clean Python or Node.js code, fully documented
- Secure auth (OAuth 2.0, API keys, JWT)
- Error handling, retry logic, and logging
- Tested and production-ready
- Full handover with explanation
Why clients choose me:
- 10+ years integrating APIs across industries
- I speak both technical and business language
- Fast delivery, clear communication
- Post-delivery support included
From simple webhook triggers to complex multi-service architectures I'll build it right the first time.
Message me with your use case before ordering I'll confirm it's feasible and give you a clear plan.
