Tools & Technologies
Common Questions
I follow RESTful conventions with proper HTTP methods, standard status codes, cursor/offset pagination, versioning (e.g., /v1/), rate limiting, and comprehensive standardized error handling. All APIs come with Swagger/OpenAPI interactive documentation.
Yes. I've integrated payment gateways (Stripe, Razorpay), social media APIs (Meta, YouTube), mapping services (Google Maps), CRM systems (HubSpot, Salesforce), and many more into complex production applications.
Absolutely. I've built APIs powering Flutter, React Native, and native iOS/Android apps with JWT authentication, real-time WebSocket features, and highly optimized JSON payloads for mobile performance.
I utilize database query optimization, Redis for response and object caching, database read-replicas, and horizontal scaling of the API servers behind a load balancer to maintain sub-100ms response times.
