Project details
I will integrate one third-party API into your existing web or SaaS application using JavaScript or TypeScript.
This service is suitable when your product needs to connect with an external platform for payments, CRM data, email, SMS, maps, analytics, file storage, scheduling, or another documented service.
Depending on your selected package, the integration can include:
• REST API connection
• API-key, bearer-token, or OAuth authentication
• Request and response handling
• Webhook configuration
• Data mapping and validation
• Database or application workflow connection
• Error handling and basic logging
• Sandbox testing
• Deployment assistance
• Source code and setup documentation
The scope covers one third-party service with the number of endpoints, pages, and workflows defined in your selected package.
This project does not include building a complete SaaS application, developing a full backend from scratch, integrating multiple unrelated services, or paying for third-party subscriptions.
Provide the API documentation, describe the required data flow, and share test access so I can review the integration requirements.

Need Help Fixing Solidity Contract Deployment
Sohaib did a great job fixing the Solidity contract issue. He quickly identified the bytecode size problem and optimized the contract so it deployed successfully. Communication was smooth and professional. Highly recommended.

What I build:
- OpenAI and Claude integrations that help users find information faster, automate repetitive work, and create better customer experiences from intelligent chatbots to document processing pipelines and AI assisted product features.
- SaaS MVPs built with Next.js, React, Node.js, and PostgreSQL. Clean architecture from day one so your product does not need a full rewrite six months after launch.
- AI agents and RAG systems that connect your internal data to LLMs, so your team stops searching manually and starts getting instant, accurate answers from your own knowledge base.
- Full-stack web applications from frontend to backend, React and Next.js on the frontend, Node.js and PostgreSQL on the backend, deployed on AWS or Vercel.
- Automation workflows using n8n, Make, and Zapier that eliminate manual work, connect your tools, and run reliably without you watching them.
You are in the right place if:
You are a startup founder who needs an AI powered product or SaaS built correctly the first time. You have a business that needs AI integrated into an existing app or workflow. You want one developer
who handles the full scope frontend, backend, AI, and deployment without coordinating five different freelancers.
Not the right fit if:
You need a formal machine learning researcher or data scientist. You are looking for the cheapest option on the platform.
Send me your project details and I will come back with a practical approach tailored to your requirements.
