You will get Third-Party API and Service Integration
Project details
I integrate third-party services into existing web applications and backends. Most clients need a payment gateway, CRM connection, email service, or webhook handler added to a Node.js backend that is already running. I handle the full integration — the API connection, webhook verification, event processing, error handling, and retry logic so failures do not silently break things in production. The code I deliver is clean, tested, and documented so your team understands exactly how the integration works.

About Shivam
Full Stack Developer | Node.js, React & REST API Specialist
Indore, India - 1:53 pm local time
On the backend I work primarily with Node.js, Python, MySQL, and MongoDB. I handle payment gateway integrations, role-based access control, admin panel APIs, and the kind of backend plumbing that keeps a product stable under real usage.
On the frontend I build with React and Next.js. I focus on clean data flow between the API and the UI, predictable state handling, and accurate implementation of designs. I work well alongside designers and can own the full integration from endpoint to interface.
I write structured, documented code. I do not take shortcuts that create problems in six months.
If you have an existing codebase I can work inside it without disrupting what is already running.
If you have a backend that needs extending, stabilizing, or rebuilding in parts, let me know what you are working on.
