    Redesign of Existing Ecommerce Website - ASP.NET Core / SQL Server It has been a pleasure working with Igor and his team.
    They have faithfully replicated the Figma website mockup in their work.
    They are easy to communicate with and responsive to your requests.

    C# / SQL Development work for Backend Igor was able to take over the project and complete it successfully, and supply additional resources when our project needed more work.
    Igor and TwinCore are an amazing resource, and if you have development work I'd highly recommend them.
    He's knowledgeable, capable of producing great code, and solving complex problems.
