Is your web application isolated, or do you need to connect it with external platforms to automate your business? I specialize in designing custom backend structures and seamlessly integrating robust third-party APIs that make your software smarter, faster, and fully automated.

Whether you need to process secure payments, sync user data with a CRM, or pull live data feeds, I handle the complex architecture so you don’t have to.

What I deliver with this service:

Payment Gateways: Ironclad integrations with Stripe, PayPal, or Braintree (including custom subscription logic, checkout flows, and webhooks).

CRM & Marketing Automation: Seamless data synchronization with HubSpot, Salesforce, Mailchimp, or custom automated workflows.

Custom API Development: Building secure, scalable, and fully documented RESTful and GraphQL APIs from scratch using Node.js/Express.

Data Feeds & Synchronization: Processing complex JSON structures, live data streams, and ensuring real-time data rendering without performance lags.

Authentication & Security: Implementing secure token-based authentication (JWT, OAuth 2.0) and encrypted data handling to safeguard user privacy.

Why choose me?
I don’t just write integration scripts; I build optimized server communication loops that prevent data loss, minimize loading times, and scale easily as your user base grows.
