I will develop a custom web app saas or dashboard in nextjs and typescript


About this gig
Need a tool that does exactly what your business needs? I build custom web apps and SaaS products, from MVP to live product.
What I build:
- Web applications and internal tools
- SaaS products with login, roles and subscriptions
- Admin dashboards and reporting panels
- Integrations with the APIs and platforms you already use
Stack: Next.js, React, TypeScript, Tailwind, Node.js and PostgreSQL. Deployed on Vercel, ready to scale.
I am building FlowDocs, my own SaaS for invoice and VAT management for companies in Portugal. It receives invoices and receipts, extracts the values, identifies the VAT and organises everything by supplier. It is still in development, and it is why I know what it takes to ship a real product instead of a demo.
What you get: working software, clean and documented code, the source code in your hands, and a person who explains what was built and why.
Send me a message with the idea or the process you want to turn into software and I will tell you how I would build it.

FAQ
Do I own the code?
Yes. The code is yours and I hand over the full repository at the end. No lock-in and no monthly fee to me.
What technology do you use?
Nextjs and TypeScript, with the database and API layer chosen for your case. I explain the choice in plain language before we start building.
I only have an idea, not a specification. Is that a problem?
Not at all. We start from a short brief, I turn it into a scope with screens and priorities, and only then do we agree on the package.
Can you keep working on it after delivery?
Yes. New features or maintenance are quoted separately as a custom offer. There is no obligation to continue.
Are there costs besides this Gig?
Hosting, the database plan and any paid API you choose are billed to you, not to me. I tell you what is needed and roughly what it costs before we start, and I pick the cheapest option that fits.
