FAQ
What do I need to provide before you start?
Just a brief description of what your app does, what data you need to store, and any features you want (like user login). If you have a design or wireframe, even better — but not required. I'll guide you through everything!
What is an API and do I really need one?
An API is what lets your website or mobile app talk to a database. If your app needs to store data, handle logins, or process payments — yes, you need one. Think of it as the "brain" of your app
Can I use this with my existing frontend or mobile app?
Absolutely! The API I build works with any frontend — React, Vue, Flutter, Swift, Kotlin, or even plain HTML. I'll provide clear documentation so your frontend developer can connect easily.
Do you offer support after delivery?
Yes! I include a README with setup instructions and I'm available for questions after delivery. If you need ongoing maintenance, we can discuss a separate arrangement.
What tech stack do you use?
I primarily work with Node.js, Golang, and Laravel for the backend, with PostgreSQL or MongoDB for the database. I'll recommend the best fit based on your project needs. All code is clean, tested, and production-ready.
