I will build a client portal or custom web app
Ninh Le
About this gig
Your customers or partners shouldn't have to email you to ask "what's the status?". I build secure portals and web apps where they log in and see everything themselves.
What I build:
- Client & partner portals: orders, jobs, documents, status, invoices
- Internal tools and dashboards for your team
- SaaS MVPs: login, database, core feature, ready for first users
- Fast, mobile-friendly websites
Connected to your tools:
Zoho CRM, Airtable, Stripe, n8n, Twilio and any REST API, so the portal shows live data, not copies.
Real example: For a German service marketplace I built a partner portal with an order book where partner companies log in and manage their assigned jobs. No more status emails.
Tech: Next.js / Astro, Tailwind CSS, Cloudflare Workers, SQL database, REST APIs. Fast, secure and low-cost to host.
Why me:
- M.Sc. Applied AI & Data Science, B.Sc. Mathematics (RWTH Aachen)
- Built production portals and automations for European businesses
- English and German
Message me before ordering with what your users should be able to do, and I'll send a clear plan and fixed price.

My Portfolio
FAQ
Do I own the code?
Yes. You get the full source code and everything is deployed to your own account.
Where is it hosted and what does it cost?
Usually Cloudflare: for small portals often free or a few dollars per month. I'll recommend the cheapest option that fits.
Can users only see their own data?
Yes. Each user logs in and sees only their records. Admins can see everything.
Can it connect to my CRM?
Yes: Zoho CRM, Airtable, HubSpot, Google Sheets or any tool with an API.
What do you need to start?
A list of what users should do in the portal, plus sketches or example sites you like.
Can you add features later?
Yes. Order the "Additional feature" extra or message me for a custom offer.
