What is full stack development?

Full stack development means building every layer of a web system: the database, business rules and APIs on the back end, and the screens users see on the front end. In my case that means C# and .NET with SQL Server on the back end and Angular on the front end, with one person accountable for the whole solution.

Who it is for

  • Companies running operations on spreadsheets that need their own system
  • Teams that want to evolve or rewrite an old MVC system
  • Businesses with specific rules that off-the-shelf software does not cover
  • Logistics, healthcare and service companies that need a custom ERP

Problems it solves

  • Information scattered across spreadsheets, emails and disconnected systems
  • A slow legacy system that is hard to maintain and nobody wants to touch
  • Expensive licenses for software that does not fit the process
  • Manual rework and typing errors every day

What can be built

  • Dashboards and forms with validated business rules
  • Login, access profiles and role-based permissions
  • Reports, Excel/PDF export and filters
  • Optimized SQL Server queries for high volume
  • Integration with APIs, ERPs and external services
  • Cloud deployment (Azure) with separate environments

How it works

  1. 1

    Kick-off call. I learn the problem, who uses the system and what success looks like for you.

  2. 2

    Written scope. We define what goes into the first version and what comes later.

  3. 3

    Architecture and prototype. I model the data and main screens before writing production code.

  4. 4

    Iterative deliveries. Short releases you test and approve — no black box.

  5. 5

    Release and support. Deployment, close follow-up in the first weeks and documentation.

What you get

  • Responsive web system in production
  • Documented API
  • Modeled and versioned database
  • Source code and credentials in your company’s name
  • Technical and user documentation
  • Follow-up period after delivery
  • C#
  • .NET 8
  • ASP.NET Core
  • SQL Server
  • Angular
  • TypeScript
  • Azure

How much does it cost?

The price depends on scope: number of screens and business rules, integrations and deadline. After the kick-off call you get a written proposal stating what is included and what is not — no surprises halfway through.

How long does it take?

A first usable version is usually ready in weeks, not months. Larger systems are delivered module by module so your team can start using them early. The exact timeline goes in the proposal.

Frequently asked questions

Why .NET and Angular?

They are mature technologies with long-term support from Microsoft and Google, great performance and a large talent pool. That lowers the risk of your system ending up without maintenance.

Can you evolve an existing system?

Yes. I have experience with .NET Framework, MVC and Razor systems. I review the current code and suggest evolving it step by step or rewriting it, based on the cost and risk of each path.

Does my company own the code?

Yes. Repository, database and cloud accounts belong to your company from day one.

Does the system work on mobile?

Yes, the screens are responsive. If field usage is heavy, I can also build a Flutter or React Native app on top of the same API.
