About this gig
A beautiful frontend is useless without a powerful, secure backend.
Stop relying on AI code and insecure endpoints. I build scalable, production-ready APIs and backend systems for your products.
Whether you need Stripe payments, complex databases, or a custom API from scratch, I engineer solutions that handle traffic, protect user data, and scale with your business.
What I build for you:
- Custom REST & GraphQL APIs with clean versioning and docs
- Third-party integrations: Payment gateways, CRM/Marketing tools, shipping/logistics platforms, AI tools, and business systems, messaging providers, Analytics & tracking.
- Database design & optimization (PostgreSQL, MongoDB, MySQL, Redis)
- Secure authentication: JWT, OAuth 2.0, NextAuth, Clerk
- Business logic: webhooks, cron jobs, background tasks and more.
Why choose this gig
- Security-first: Rate limiting, OWASP, input validation (Zod)
- Clean Code: I write code that other developers can actually read and maintain.
- Scalable: Code written to handle growth, using microservices or modular monolith architecture.
Don't let bugs ruin your product.
Message me and lets build it right.

FAQ
How do you ensure the API is secure?
Security is my priority. I implement industry standards including JWT (JSON Web Tokens) for authentication, Rate Limiting to prevent spam/DDoS, Input Validation (Zod/Joi) to stop malicious data, and protection against SQL Injection/XSS attacks.
Will you provide documentation on how to use the API?
Yes! For Standard and Premium packages, I provide a Postman Collection or Swagger/OpenAPI documentation. This makes it extremely easy for your frontend team (or yourself) to test and integrate the endpoints.
Which technologies do you use?
I specialize in Node.js (Express/NestJS) and Python (FastAPI/Django). For databases, I work with PostgreSQL, MongoDB, and MySQL. If you have a specific tech stack requirement, please let me know—I adapt quickly.
Do I get the complete source code?
Absolutely! You get: - Full source code with detailed comments - Documentation explaining how everything works - Setup instructions - No licensing restrictions - it's 100% yours You'll have complete ownership and can modify it however you need.
What database do you use?
I work with whatever fits your project: - PostgreSQL (recommended for production) - MongoDB (great for flexibility) - MySQL/MariaDB - SQL Server (for .NET projects) Already have a database? I'll integrate with your existing one. Need help choosing? I'll recommend the best.
Can you integrate third-party services like Stripe or OpenAI?
Absolutely. I have extensive experience integrating Payment Gateways (Stripe/PayPal), AI Models (OpenAI/Anthropic), SMS services (Twilio), and Email providers (SendGrid/Resend) securely into your backend logic.
Will this work with my existing project?
Yes! I can integrate authentication into existing applications or build from scratch. I'll review your current codebase structure and implement auth following your project's conventions. Message me with details about your project, and I'll confirm the approach!
Do you also build the Frontend (React/Next.js) for this gig?
This gig is specifically for Backend API & Database development. However, since I am a Full-Stack Developer, I can build the Frontend UI for an additional fee. Please message me to discuss a "Full Stack" custom offer.
