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.
