I will build a custom internal tool or admin dashboard


About this gig
I build the internal tools your team duct-tapes together in spreadsheets admin panels, dashboards, client portals, approval flows that never make the roadmap.
Production-grade internal tools in Next.js + Supabase + TypeScript: real auth, proper database design, row-level security, deployed and ready to use. Not a no-code toy that breaks at scale. Fixed scope, fixed price, shipped.
What you get:
- A deployed, working web app (Vercel) not a mockup
- Clean, typed, documented code you fully own
- Database design with row-level security, not an unsecured backend
- Auth and role-based access done properly
- Premium: a real AI feature built to handle the model failing gracefully
I care about the last 10% AI-generated code gets wrong the race condition, the policy that leaks, the edge case. Your tool still works on day 90.
Message me your idea before ordering so I can confirm scope.
New here, building my reviews launch prices below market. Order early.

FAQ
Do I own the code?
Yes, 100%. You get the full source, it's deployed under your account, and there's no lock-in or ongoing fee to me.
Is "internal tool" only for internal staff?
No — it covers admin dashboards, internal ops tools, client-facing portals, and small internal web apps. If people on your side use it to get work done, it fits.
What if my idea is bigger than one package?
Message me first. I'll either scope it into a package + extras, or give you a custom fixed-price quote. I don't start work I can't ship cleanly.
Do you use AI to write the code?
I use AI as a tool the way every serious dev does — but I architect and own every decision. The database design, security, and the failure cases are mine, not a model's guess. That's the part that matters in production.
Can you work with my existing codebase?
For adding a tool/feature to an existing Next.js/Supabase app, yes. For legacy stacks, message me first so I can confirm fit before you order.
