I specialize in engineering robust server-side architectures, clean RESTful APIs, and efficient database systems designed to handle real-world traffic. Whether you need a brand-new backend built from scratch, third-party API integrations, or performance optimization, I deliver well-documented and maintainable code built to industry standards.
What I Can Do For You
- API Development: Custom REST APIs and GraphQL services built with Node.js, Python, or Go.
- Database Architecture: Schema design, indexing, and query optimization for PostgreSQL, MySQL, and MongoDB.
- Authentication & Security: Secure Auth systems featuring JWT, OAuth 2.0, and Role-Based Access Control (RBAC).

- Third-Party Integrations: Payment gateways (Stripe, PayPal), webhooks, and external SaaS APIs.
- DevOps & Deployment: Containerization with Docker and deployment to AWS, Vercel, or Render.

FAQ
Can you help deploy the backend to my cloud server?
Absolutely. Cloud deployment (AWS, Vercel, Render, DigitalOcean) can be included in the order or added as a Gig Extra. I will set up environment variables, build scripts, and production server configurations.
What do I need to provide to get started?
A brief overview of your application's logic, front-end design/wireframes (if available), and a list of required features or third-party services (e.g., Stripe keys, email service credentials).
Do you work with existing codebases or legacy backends?
Yes, I can debug, refactor, or add new microservices to existing codebases. Please send me a message with access to your repository so I can evaluate the code prior to ordering.
What happens if I find a bug after the order is completed?
I offer post-delivery support to fix any bugs or logic discrepancies that were part of the agreed scope of work.
