FAQ
Will I get the source code and full ownership?
Yes. Once the order is marked complete, you receive the full source code, database schema, API documentation, and deployment instructions. The code is yours to keep, modify, and deploy anywhere.
Do you write tests?
Yes, basic unit tests are included in Standard, and full test coverage (unit + integration) is included in Premium. If you need a specific testing framework (Jest, Mocha, Vitest), let me know.
Can you integrate third party APIs and services?
Absolutely. I regularly integrate Stripe, PayPal, SendGrid, Twilio, AWS S3, OpenAI, Google Maps, Onfleet, RudderStack, and many more. List your needs in the requirements.
Do you provide API documentation?
Yes. Basic gigs get a Postman collection. Standard and Premium include Swagger/OpenAPI documentation, which is interactive and easy for your frontend or mobile team to consume.
REST or GraphQL, which should I choose?
Both are great. REST is simpler and works for most projects. GraphQL is better if your frontend needs flexible queries or multiple data shapes. If you're unsure, I'll recommend based on your project.
Can you work with my existing backend?
Yes. I take on refactoring, feature additions, performance tuning, and migrations from PHP, Python, or older Node.js codebases. Just share repository access after ordering.
What about deployment and DevOps?
Premium includes full AWS deployment with CI/CD. For Basic and Standard, I'll deploy to your chosen platform (Render, Heroku, DigitalOcean, etc.) and walk you through the setup.
