Veelgestelde vragen
Which language should I choose?
Python for AI and data features, Node.js if your team works in JavaScript, Golang for high traffic and speed. I'll recommend one for your project before we start.
What if it's late or not what we agreed?
You get your money back. We agree on the scope and the delivery date before I start. If I miss either, I refund you.
Can you work on my existing backend?
Yes. I fix bugs, add endpoints, speed up slow queries, and help an existing backend scale.
Can you build the frontend too?
Yes. I build web apps and iOS and Android apps in my other gigs, or I connect this backend to the frontend you already have.
Which databases do you use?
PostgreSQL, MySQL or MongoDB, plus Redis for caching. Supabase or Firebase also work if you prefer them.
Will you deploy it?
Standard and Premium are deployed to your cloud. Starter comes with Docker, ready to deploy, or you can add the Deploy + CI/CD extra.
Do you write tests and docs?
Yes. Core endpoints get automated tests, and you get API docs (Swagger or a GraphQL schema) your frontend team can use.
Is it secure?
Yes. Login and roles, input validation, rate limits, secrets kept out of the code and least-privilege database access.
Can it handle growth?
Yes. I design for scale with caching, queues and background jobs, and split into microservices only when you need it.
Do I own the code?
Yes. All code is yours, delivered in your own repository.
