About this gig
Looking for APIs that increase performance, protect data, and boost revenue.
Fast, secure, and scalable backends built with Node.js and Express.js for real business results. With 10+ years of experience and 490+ backend systems delivered, these APIs handle 500K+ requests/month, reduce response times by up to 40%, and help businesses increase conversions by 15-25% through smoother performance.
A weak backend costs users and revenue. A strong API improves checkout success, minimizes downtime, and keeps applications reliable as traffic grows.
What You Get:
- Custom REST API development
- REST API integration
- Secure authentication (JWT, OAuth2)
- Stripe & payment gateway integration
- Scalable databases (MongoDB, PostgreSQL, MySQL)
- Clean, production-ready code
Tech Stack:
Node.js, Express.js, REST APIs, API Integration, Python
Systems built with this approach reduce failed transactions by 30% and scale smoothly to 50K+ active users without breaking.
Your backend is your revenue engine. If its slow or insecure, growth stops.
Book a free NDA-protected consultation and lets build an API that performs, protects, and pays off.
