IT Services

I have been a professional IT consultant and software developer since 1993. If you have a software project that needs to be realized, please contact me for more information.

Custom software development

Over 25 years of software development experience, at your service.

  • Languages: C#, ASP.NET/MVC, .NET Core, PHP, Delphi
  • Web development: Javascript, jQuery, Webpack, HTML/CSS, Bootstrap, Vue.js
  • Databases: MySQL, SQL Server, SQLite

I have experience from building banking systems, CTI/telecom applications, custom application servers, components and build tools, CRM/helpdesk systems, and lots of smaller projects.

Case study:

Custom web application built for Juristbyrån Ekered & Co - a tool for Swedish city government departments to determine legal assistance levels to disabled citizens.

"Mats Gefvert was the obvious best choice when we had to outsource the coding of our application. Not only did we have previous experience from Mats, we also considered the fact that he had previous experience of coding applications aimed for large number of simultaneous users within govermental institutions and organizations. Quality and reliablility are paramount in our enterprise and thus we choose subcontractors accordingly."

-- Petter Åström, Chief of Operations, e-beslut AB and founder/part owner, Juristbyrån Ekered & Co, Sweden.

Case study: Be Better Online

Be Better Online is an online marketing agency that helps business "be better online"; everything from search engine optimization, web page improvements, advertising and social media campaigns.

My role was to improve their internal systems and providing efficient tools for the staff, building task management systems and reporting tools, improving their existing systems, as well as a complete overhaul of their invoicing system.

Custom websites

Web technologies have almost completely taken over normal application development.

It's common today to build on top of WordPress, Drupal or other frameworks. I prefer to build custom frameworks for web application development, whether websites or full-fledged applications with public-facing API's.

Case study: Kennebec Valley Assembly of God

Website built using a minimalistic PHP framework with editing capabilities.
With literally no administrative interface or databases, it presents extremely few attack surfaces and is yet easy to manage and update.

Mobile development

Mobile apps for Android or iOS are incredibly popular. However, the experience of unifying Android or iOS apps into a single codebase has been difficult. Using Dart and Flutter, this can now easily be overcome with small, efficient and native applications.
