FAQ
What is the difference between a website and a web application?
A standard website is mostly informational (like a blog or portfolio). A web application is interactive, handles user accounts, processes data, and performs specific tasks (like a CRM, SaaS dashboard, or e-commerce platform). I specialize in building these complex, interactive web apps
Do I need SEO for my web app?
It depends on your goals! If you are building a public platform (like a directory or marketplace), yes, and Next.js is perfect for ranking on Google. If you are building a private admin dashboard or internal company tool, SEO is unnecessary, and we will focus entirely on speed, security, and user ex
Do I need to provide the UI/UX design?
I work best when provided with a design file (like Figma or Adobe XD). However, if you do not have a design, don't worry! I can build a clean, modern, and responsive UI using Tailwind CSS and component libraries based on your ideas and reference sites.
Will you deploy the web app, or just send me the code?
I offer full-cycle development. Depending on your needs, I can deploy your application to modern platforms like Vercel or Railway, or set it up on a custom VPS using Docker. Just let me know your hosting preference during our initial chat!
Do you offer support or maintenance after the project is finished?
Absolutely. I want your project to succeed long-term. I offer custom maintenance agreements for bug fixes, performance updates, and adding new features after the initial launch.
What if I don't know exactly what technical stack I need?
That is exactly what I am here for! You don't need to be a technical expert. Just send me a message explaining your business idea and what you want the app to do, and I will recommend the best architecture and database structure for your specific needs.
Why do you require a message before I place an order?
Web applications are highly customized, and standard gig prices rarely cover complex custom logic. By discussing your project first, I can give you a 100% accurate price and timeline, ensuring we are on the same page and avoiding any need for cancellations.
