FAQ
Can you optimize my existing slow API?
Yes, I specialize in performance optimization. I've achieved 95% improvement in API response times through query optimization, proper indexing, caching strategies, and code refactoring. Share your current codebase for a free assessment.
Can you help deploy my backend to AWS or cloud servers?
Yes, I provide complete deployment services including Docker containerization, AWS EC2 setup, S3 configuration, Nginx proxy, SSL certificates, and CI/CD pipelines using GitHub Actions. I also offer DigitalOcean and custom VPS deployment.
Can you integrate third-party APIs into my backend?
Yes, I regularly integrate payment gateways (Stripe, PayPal), email services (SendGrid, Mailgun), SMS APIs (Twilio), social media APIs, and any custom third-party API your project requires. All integrations include proper error handling and retry mechanisms.
What Python frameworks do you use for backend development?
I specialize in Django and FastAPI for backend development. For REST APIs, I use Django REST Framework which provides robust features for authentication, serialization, and viewsets. FastAPI is my choice for high-performance async APIs requiring maximum speed.
