About this gig
IMPORTANT: Message me before ordering so we can confirm
scope and timeline.
Spreadsheets and no-code tools stop working once your data
and your team grow. I build custom web applications that
handle the real thing: your data model, your workflow,
your rules.
WHAT I BUILD
- Internal tools and admin dashboards
- Client portals with role-based access
- Data platforms with tables, filters and charts
- Real-time dashboards over WebSocket
- REST APIs and third-party integrations
- SaaS products with accounts and billing
WHAT YOU GET
- Clean, documented code you fully own
- Secure JWT authentication and role permissions
- MySQL database designed around your data, not a template
- Admin panel to manage users, records and content
- Responsive interface that works on phone and desktop
- Deployed on your server with SSL and process manager
- Handover walkthrough so your team can run it
STACK
Next.js, TypeScript, React, Node.js, Express, MySQL,

Hi, I'm Marius — a full-stack web developer with an
engineering background (M.Sc. in Applied Physics).
I build complete products, not just pages: React/Next.js
+ TypeScript on the front, Node.js and MySQL on the back,
Stripe for payments, and deployment on your own server
with SSL.
Recent work includes a nutrition SaaS with AI scanning and
subscription billing, a subscription platform for a digital
artist, and a business site for a stone manufacturer.
You'll get clean code, clear communication, and a site that
still works after launch.
Tell me about your project — I reply fast.

FAQ
Why do I need to contact you before ordering?
Web apps vary enormously in scope - a simple internal tool and a multi-role platform are different projects. Fifteen minutes of conversation gets you an accurate quote instead of a mid-project surprise.
What kind of applications do you build?
Admin dashboards, internal tools, client portals, data platforms, booking and inventory systems, and SaaS products. If it needs a database, user accounts and custom logic, it fits.
Can it connect to systems I already use?
Yes. If it has an API, I can integrate it - payment providers, email services, CRMs, analytics, or your own existing database. Tell me what you use and I'll confirm what's possible.
Will I own the code?
Completely. Full repository, database and deployment, all under your accounts. No lock-in and no ongoing fee to me.
Can my team manage it after delivery?
Yes. Every build includes an admin panel for day-to-day management, plus a handover walkthrough. For code-level changes you can hire anyone - it's standard Next.js and Node.js, not a proprietary system.
Where will the app be hosted?
On your own server or cloud account, so you keep full control. I handle deployment, SSL and process management. If you don't have a server yet, I'll recommend an option that fits your load.
What if something breaks after delivery?
Bugs in what I built are fixed free within 14 days of delivery. Beyond that, or for new features, I offer a monthly support option - just message me.
