Über diesen Service
Are you looking for a reliable engineer to connect third-party services to your store or app? With more than 100 successful integrations delivered, I specialise in building robust API connections for e-commerce and business platforms. Whether you need a payment gateway, SMS/OTP service, CRM, email marketing tool, or a completely custom API, I can help you automate workflows and improve user experience.
️ Top integrations: Stripe, PayPal, Coinbase, Twilio, SendGrid, Nexmo, ActiveCampaign, Google Sheets, Blockchain.com, CoinPayments, USPS & other shipping/carrier APIs.
️ Platforms supported: Shopify, Wix, WordPress, WooCommerce, and custom SaaS.
️ Tech stack: PHP, Python, NodeJS, REST/GraphQL, OAuth2, JSON & XML.
My process:
1. You share API documentation and describe your goal.
2. I assess complexity and propose a clear plan with a fixed quote.
3. I develop and test the integration in a staging environment.
4. I deliver the final integration with documentation and support.
What sets me apart? I write clean, secure code, handle edge cases and error logs, and communicate transparently. You get clear documentation so your team can maintain the integration after delivery.

FAQ
What do you need from me to get started?
I'll need a clear description of your requirements, any relevant API documentation or endpoints, and access credentials (API keys or tokens) for the services you want to integrate. This information helps me understand the project and start the integration smoothly.
How long will the API integration or development take?
Delivery time depends on the complexity of the project. Simple integrations can be done within a couple of days, while more complex or multiple API projects may take longer. I always communicate the timeline clearly and deliver on time.
What technologies do you use for API integration?
I typically use PHP, JavaScript (Node.js) or Python for API integrations and development, depending on what fits your project best. I'm also experienced with official SDKs and RESTful API calls, ensuring efficient and reliable results.
Can you build a custom API or handle multiple APIs in one project?
Yes. I can develop a custom API from scratch tailored to your needs or integrate multiple third-party APIs into your system. We'll discuss your goals and make sure the solution covers everything you need.
Do you provide support after the integration is completed?
Absolutely. I stand by my work and will provide support to fix any issues or answer questions that arise after delivery. Your satisfaction and the smooth functioning of the integration are my top priorities.
