FAQ
What programming languages and frameworks do you use for APIs?
I build APIs primarily with Python (Django REST Framework, FastAPI) and Node.js (Express, NestJS). The framework choice depends on your project; FastAPI for high-performance AI backends, Django for complex business logic, Node.js for real-time features.
Can you integrate any third-party API?
Yes — I can integrate ANY API with proper documentation. I've integrated Stripe, PayPal, OpenAI, Claude, Twilio, SendGrid, Google APIs (Maps, Auth, Drive, Sheets), AWS services (S3, SES, Lambda), social media APIs, CRM systems, and hundreds more. If it has an API, I can connect it.
Do you build APIs from scratch or only integrate existing ones?
Both. I design and build complete REST APIs from scratch — authentication, endpoints, database, business logic — AND integrate third-party services into your system. Most projects need a combination: a custom API that also connects to external services like Stripe or OpenAI.
Can you add AI features to my API?
Yes! I build API endpoints that incorporate AI — chatbot APIs using OpenAI/Claude, smart search with vector embeddings, content generation endpoints, image recognition, and recommendation engines. My MS in Artificial Intelligence means I understand the technology deeply, not just making basic API ca
How do you handle Stripe payment integration?
I've built complete Stripe payment systems including one-time charges, recurring subscriptions, metered billing, webhook event handling, refund processing, and Stripe Connect for marketplace payouts. Production-tested code, not copy-pasted from tutorials.
Will my API include proper documentation?
Yes — every API I deliver includes Swagger/OpenAPI interactive documentation with endpoint descriptions, request/response examples, authentication details, and error codes. Your team can test endpoints directly in the browser and start integrating immediately.
Can you build real-time APIs with WebSocket?
Absolutely. I built a complete trading platform with real-time WebSocket APIs handling live price updates, order execution, and instant notifications. Real-time chat, live dashboards, push notifications, and event-driven architectures are core capabilities.
Do you provide the source code?
Yes! You get complete ownership of all source code — API endpoints, database schemas, integration code, tests, and documentation. Full repository access with clean, commented code. No vendor lock-in.
How do you ensure API security?
Every API includes proper authentication (JWT/OAuth2), input validation, rate limiting, CORS configuration, SQL injection prevention, and encrypted data handling. I follow OWASP security best practices — your API is production-safe from day one.
What do you need from me to get started?
Message me with: (1) what your API needs to do, (2) which third-party services to integrate (Stripe, OpenAI, etc.), and (3) any existing code or database. I'll review and send a detailed technical proposal with architecture plan, timeline, and pricing — usually within 1 hour.
