I will develop your web app with login, database and admin panel
Douglas M
About this gig
Do you need more than just a pretty website? I build real web applications complete with user login, databases, and admin panels.
WHAT I BUILD
- Web apps with user authentication (email, Google, magic links)
- Admin panels so you can manage your data independently
- Real databases using Supabase with user-level permissions (RLS)
- Dashboards, forms, reports, and Excel exports
- Integrations: payments, WhatsApp, email, Google Sheets, external APIs
- Truly responsive design: mobile, tablet, and desktop
WHO IT'S FOR
Founders who need an MVP to validate an idea. Businesses currently relying on spreadsheets that need a proper system. Agencies that need a real backend to back up their designs.
HOW I WORK
Before writing any code, I ask the tough questions: what problem are you solving? Who is the user? What happens when something goes wrong? Most MVPs fail because they skip this step, not because of the code itself.
You own the code and the database. You aren't locked into working with me.
Tell me what you want to build, and Ill let you know if its a one-week or one-month project. No strings attached, straight to the point.

FAQ
What exactly is a "screen"?
A view with a primary function: a customer list, a sign-up form, a dashboard. Login and password recovery screens don't count; they are always included. If you have questions about your project, send me your requirements list, and I’ll give you a quote before you buy.
2. Do you use AI to build?
Yes, to speed up repetitive tasks. However, I manually review the database design, security rules, and testing—one by one. AI writes code quickly, but it also quickly introduces security vulnerabilities—which is why the work doesn't stop there.
Do I own the code?
Yes. I hand over the repository and the Supabase project in your name, with owner access. You can continue working with another developer whenever you want. I don't hold clients hostage.
Can I edit the content later without knowing how to code?
That’s what the admin panel is for. You can create, edit, and delete data from there without touching any code. If you need to change text or images on public pages, I make those editable as well.
What are the monthly maintenance costs?
Usually $0 at the start: Supabase and hosting offer free plans that easily handle a new project. As you grow, I’ll explain exactly when and how much you’ll need to pay. I’ll tell you this upfront, not after the fact.
What if my idea is bigger than the Premium package?
Even better. Message me before buying, and we can put together a custom quote. I’d rather tell you your project costs $1,500 and takes three weeks than sell you a Premium package that falls short—leaving us both disappointed.
