I will build custom api integrations, stripe billing and mcp servers for saas
Hassan Ali
About this gig
Your SaaS needs to talk to other tools, take payments reliably, or let AI work with your real data. I build integrations that actually hold up in production.
API integrations:
- Connect your app to CRMs, payment, email, calendar, accounting or any REST/GraphQL API
- Webhooks, OAuth, data sync and error handling done properly
- Custom APIs for your own product (Node.js or Python/FastAPI)
Stripe billing:
- Subscriptions, trials, usage-based and one-time payments
- Checkout, customer portal, invoices and failed-payment retries
- Secure webhooks that keep your database in sync
MCP servers and AI agents:
- Custom MCP servers so Claude, ChatGPT or Cursor can use your app's data and tools
- AI agents that read, update and act on your business systems
Every order includes clean code on GitHub, setup docs and a walkthrough of how it works.
I run Nexore Digital Agency and build with Next.js, Node.js, Python, PostgreSQL and Supabase daily.
Message me before ordering with the tools you want connected. I'll confirm scope and give you a clear quote.

FAQ
Q: Which APIs can you integrate?
A: Any service with a documented REST or GraphQL API. Common ones are Stripe, HubSpot, Salesforce, QuickBooks, Xero, Google, Slack, Twilio, OpenAI and Claude. Send me the name and I'll confirm.
Q: What is an MCP server and do I need one?
A: It's a connector that lets AI assistants like Claude or ChatGPT safely read and act on your app's data. If you want customers or your team to use AI with your product, you need one.
Q: Do I need a developer account or API keys?
A: Yes, integrations run under your own accounts. I'll show you how to create the keys and share them securely. Never paste them in chat.
Q: Can you work inside my existing codebase?
A: Yes. Invite me to your GitHub repo and I'll build the integration to fit your stack and code style.
Q: What happens if an API changes later?
A: I build with error logging and retries so problems show up clearly. Ongoing maintenance is available as a monthly custom offer.
