For companies where people build their own tools

Your people built apps with AI. Put them behind your company login.

Sales has a quote calculator, the warehouse a stock report, HR an onboarding checklist, each built by someone with Claude or Lovable over a weekend. To use them across the company they need your company login and one place to live. That is a day of work per app, not a project.

What you get

Company login

Sign-in with your existing Microsoft Entra ID or Google Workspace accounts. When someone leaves, their access goes with their account.

One place for the apps

One address where the company’s internal apps live, with a list people can find.

One way to deploy

Every app deploys the same way, so the next person can update it without asking the author.

A short guide

How to add the next app, written for the people who build them.

How it works

  1. 30-minute call

    You show me the apps and where your company accounts live.

  2. One app first

    I put the most used app behind company login and into its new home, usually in a day.

  3. The rest

    The other apps follow the same path, one by one.

  4. After

    Optional monthly care for the platform and new apps.

What this is not

  • A security audit or a review of the apps’ code.
  • A rewrite of the apps.
  • A new identity system: it uses the accounts you already have.

Proof

I run a family of internal and public apps on Cloudflare with shared deploys and analytics, and I set up coding agents for teams under shared rules.

An AI coding agent as a team member, under enforced rules

The problem
Coding agents produce ten times the output and ten times the mess. A team of four wanted the speed without a slop swamp on main.
What I did
I authored the rule set shared by Claude Code and Codex: mechanical checks over written rules, lint and test gates for security, API surface and CSP, agents working on main with hooks, every PR reviewed by a human, AI-assisted content disclosed as such.
Result
In 2026 the agent opened about 30% of merged pull requests across two products and I reviewed about 85% of them. My own output went from under 1,000 to 5,000+ commits a year.

~30% PRs by agent ~85% reviewed 5,000+ commits/yr

Back-office task management: team lead of four, no product manager

The problem
A back-office tool needed new features, a UI refresh and a faster pipeline, with no product manager in sight.
What I did
I led four engineers and kept coding. Trunk-based development with CI/CD, live updates over server-sent events, a stopped parallel initiative that analysis showed would not pay off, priorities set directly with department managers.
Result
“Measurable changes in some key metrics” and “a true bias for action”, in the client CTO’s public LinkedIn recommendation.

Four side projects on Cloudflare Workers under one domain

The problem
Ideas die when deploying them costs a weekend. I wanted a path from idea to a URL in an evening.
What I did
Korpo Tłumacz, Wyrocznia, Migawki and Przemo (Agent): each a Worker with static assets, Workers AI with per-IP and global rate limits, a cost cap in a Durable Object, R2 for generated images, a first-party PostHog proxy and a CSP without inline scripts.
Result
Live at ciunkos.com/korpo-tlumacz, /wyrocznia, /migawki and /przemo. This page runs on the same pattern.

Your people built small apps with Claude, Lovable or Cursor. I put them behind your company login (Microsoft Entra ID or Google Workspace), in one place with one way to deploy, so they can be used across the company.

FAQ

Questions

Can a Lovable or Claude-built app use Microsoft Entra ID login?
Yes. Either the app signs users in with your company accounts itself, or it sits behind a login gateway that does it before the app loads.
Do we need to change our Microsoft or Google setup?
Usually only an app registration that your administrator approves. I prepare the exact steps.
How long does it take?
About a day for the first app, less for each next one.
Where do the apps run?
Where you prefer: your cloud account or a simple hosting I set up on your company’s account.
