BATTLE-TESTED MULTI-PLATFORM ACCELERATOR
From Concept to Production-Ready MVP in 14 Business Days. Web, iOS, & Android.
Your product in front of users and investors in 14 business days from the signed scope and the deposit, within an agreed functional scope. Built as one C#/.NET codebase with automated CI/CD pipelines, hosted on low-cost Hetzner and PostgreSQL, with zero vendor lock-in. You own the code from the first commit.
No sales reps. Direct talk with the lead architect.

// what is included
One fixed scope. Three platforms. Fourteen business days.
The functional scope is agreed and signed before day one. Everything below ships with it, on every MVP.
14 business days, guaranteed
Day one is the first business day after both conditions are met: the scope signed by both sides and the agreed deposit received. Days spent waiting for your materials, access or approvals move the delivery date by the same number of days.
On day 14 the web app is live on your domain, the iOS build is on TestFlight and the Android package is ready for Google Play. Approval by Apple and Google is not part of the term; it takes as long as they decide.
If the agreed scope is late, the extra work is free. Bugs in the agreed scope are fixed free, without delay.
// the unfair advantage
Cheap and fast usually costs you later.
Budget agencies and low-code tools get you a demo. Then the rewrite, the platform fees and the cloud bill arrive.
| Criterion | Typical Agency / Low-Code | >_ The DotNET Leet Approach |
|---|---|---|
| Speed | Months, one platform at a time. Or a quick low-code demo that stalls at the first custom feature. | 14 business days, fixed scope. Web, iOS and Android ship together. |
| Code ownership | Locked inside a platform or an agency repo. Leaving means a rewrite. | Your repository from day one. Standard C#/.NET that any .NET team can take over. |
| Native performance | Web wrappers and low-code runtimes dressed up as apps. | Real iOS and Android builds from the same C# codebase. On day 14 the web app is live, the iOS build is on TestFlight and the Android package is ready for Google Play. Store approval is outside the term. |
| Hosting cost | Usage-based AWS or Azure bills that grow before revenue does. Per-seat platform fees on top. | Hetzner and PostgreSQL. A flat, predictable monthly bill that keeps burn near zero. |
| Foundation | Auth, roles and deployment get bolted on after the demo. | ASP.NET Core Identity, role-based access, clean architecture and CI/CD are in before feature one. |
| Quality | Manual clicking before the demo. The first real user finds the bugs. | Automated unit and integration tests gate every release on all three pipelines. |
| After launch | A ticket queue, an hourly rate for every bug and no idea what the app is doing in production. | A bug in the agreed scope is fixed free and without delay. Grafana, Loki and Prometheus show exactly what happened. |
// architecture and stack
One codebase. Three pipelines. Zero lock-in.
Proven technology, wired together once and reused on every build, nothing exotic, nothing you cannot hire for.
Single C#/.NET codebase
Domain, API and UI live in one solution. Web, iOS and Android share the same logic, so a feature is built once.
Hetzner bare metal and cloud
Servers at a fixed monthly price. No per-request billing and no surprise invoice when traffic grows.
PostgreSQL
Open source, no license fees, runs anywhere. Your data moves with you.
ASP.NET Core Identity
Sign-up, login and role-based access from the first build. Your users stay in your database.
3x automated CI/CD
Independent pipelines for Web, iOS and Android, running from day one.
Clean architecture
Clear boundaries between domain, application and infrastructure. The MVP grows without a rewrite.
Tests in every pipeline
Unit and integration tests run on every push. A failing test stops the release before it reaches a user.
Grafana, Loki, Prometheus
Logs, metrics and alerts on your own server, fed by OpenTelemetry. No monitoring vendor, no per-GB bill.
Bugs fixed without delay
A bug in the agreed scope is fixed at no cost, straight away. You talk to the person who wrote the code.

// day 14 handover
What is in your hands on day 14.
A fixed list, agreed before day one. You know what ships, what does not, and whether this is for you at all. Day one is the first business day after both conditions are met: the scope signed by both sides and the agreed deposit received.
- Web app in productionRunning on your domain, on Hetzner servers.
- iOS build on TestFlightSigned and ready for testers and store submission.
- Android build ready for Google PlaySigned package from the same C# codebase.
- Auth and role-based accessASP.NET Core Identity, users stored in your database.
- PostgreSQL databaseOpen source, no license fees, yours to move.
- One AI featureAn assistant or agent inside the product. It can only call the C# methods you expose.
- Three CI/CD pipelinesWeb, iOS and Android.
- Automated test suiteUnit and integration tests run on every push. A red build never reaches your users.
- Observability from day oneGrafana, Loki and Prometheus on your server. Logs, metrics and alerts, no extra vendor.
- The full source codeIn your repository, on a clean architecture foundation.
- New feature ideas during the build. They wait for the next round, so day 14 holds.
- Approval by Apple and Google. You get the builds on day 14, store review takes as long as they decide.
- Admin on your side. Apple, Google, Hetzner and the AI provider run on my accounts to start, so there is nothing for you to set up. Transfer to your own accounts happens when you are ready.
- You need a throwaway demo for one pitch. A no-code tool is cheaper for that.
- The scope still changes every week and nobody can decide it.
- You want a large agency team with account managers.
guarantee
The date is guaranteed. So is the fix.
If the agreed scope is not in your hands on day 14, I keep working at no extra cost until it is. Days spent waiting for your materials, access or approvals move the delivery date by the same number of days; the scope and the guarantee stay as agreed. If a bug shows up in the agreed scope after handover, I fix it at no cost and without delay. No ticket queue.
// faq
Straight answers before the call.
Who owns the code?
You do. The repository is yours from day one. It is standard C#/.NET with no proprietary runtime, so any .NET team can take it over.
Will the apps be live in the stores on day 14?
They are submitted on day 14. Until Apple and Google approve them, your users install the iOS app through TestFlight and the Android app through Google Play internal testing, both from a link you can share. Everything runs on my developer accounts, so you need nothing set up to start. When you want the apps under your own name, they transfer to your accounts.
Is AI included?
Yes. The MVP ships with one AI feature, agreed in the scope: an assistant over your own data or an agent that performs actions in the app. The model can only call the methods you expose. Usage runs on my provider account to start and moves to yours with the rest of the handover.
What if you miss day 14?
Then I keep working at no extra cost until the agreed scope is delivered. The guarantee covers the scope we fixed before day one. The 14 days are business days, counted from the day both conditions are met: the scope signed by both sides and the agreed deposit received. Days spent waiting for your materials, access or approvals move the delivery date by the same number of days; they do not shrink the scope or the guarantee.
What happens after day 14?
You have a production app, three pipelines and the repository. Keep building with your own team or keep working with me. Nothing is locked either way.
What if I want to change the scope?
Scope is agreed before day one. New ideas go on a list for the next iteration. That is how the 14 business days hold.
What does it cost?
You get a quote after the 15-minute call, before any work begins. Fixed scope means you know the number up front. A deposit is agreed together with the scope, and the 14 business days start once the signed scope and the deposit are both in place.
What will hosting cost me?
Hetzner servers have a fixed monthly price and PostgreSQL has no license fee. You get the figure for your setup on the call. The server starts on my Hetzner account and transfers to yours when you are ready.
What do you need from me?
A clear brief, one person who can decide, and quick answers during the 14 business days. While I am waiting for your materials, access or approvals, the clock pauses and the delivery date moves by the same number of days.
How is it tested?
Unit and integration tests are written with the code, not after it. They run in all three pipelines on every push, and a failing test blocks the release. The test suite is in your repository with everything else.
What happens when a bug shows up after launch?
You report it and I fix it, without delay and at no cost, as long as it is in the agreed scope. No ticket queue and no hourly rate for my own mistakes.
How do I know what the app is doing in production?
Grafana, Loki and Prometheus run on your server from day one. You see logs, request rates, errors and response times on one dashboard, and alerts reach you before your users call.
