About us

Software that runs inside companies for years.

Skyvault is a small software company founded by Alexander Sádovský. He started in 2007 with networks and servers, moved on to the web, and since 2016 has built enterprise systems, online shops and automation under the Skyvault name.

You don't talk to a salesperson or a ticket queue. You talk directly to the person who designs and writes your project.

How we got here

  1. Networks, servers and first websites

    Running the website, network and computers of a small company. That is where the habit of fixing whatever stops working comes from.

  2. Security and internal apps at ABB

    Servers, backups and IT security at an international industrial company, and a first internal time-reporting app (PHP, Yii).

  3. Web applications and a price-comparison site

    Real-time task management, a Thunderbird extension, an app for plastics manufacturing, then the architecture of a price-comparison site on Meteor, MongoDB and Elasticsearch.

  4. Skyvault is founded

    Our own company, through which we have delivered software ever since: enterprise systems, websites, online shops and automation.

Technology we know well

We pick tools by what your company already runs and what someone will still be able to maintain in five years. Not by fashion.

Enterprise systems

Internal tools, APIs and integrations that run for years, such as outage management for a telecom network with BMC Remedy integration. Also migrations from the old .NET Framework.

  • .NET 8 and 10
  • ASP.NET Core
  • Blazor
  • EF Core
  • MS SQL Server

Websites and online shops

Company websites, online shops and web apps that work well on a phone and connect to stock, invoicing or a supplier feed.

  • PHP 8
  • Laravel
  • TypeScript
  • React
  • Svelte
  • Node.js
  • Bun
  • Tailwind CSS

Operations and infrastructure

Zero-downtime deployments, monitoring with alerts, logs and backups. CI migrations without stopping development.

Data and search

Databases and full-text search, including languages that don't separate words with spaces.

AI and automation

We use AI agents in development every day and build automation on them: collecting data from websites, processing documents, scheduled checks.

When it has to go deeper: porting language runtimes to another operating system and our own tooling in Go.

  • Go
  • C
  • C++
  • LLVM/clang
  • Python
  • Shell

Code you can read

Most of our work runs inside other companies. These projects are public.

How we work

You talk to the developer
No account managers, no ticket queue. Whoever discusses the brief with you also writes the code.
Scope and price in writing first
Before any work starts you get a written offer with the scope, the price and the timeline.
Tests and monitoring
We write automated tests and set up monitoring, so a bug shows up on our side rather than with your customers.
