Contact Us If

your current proprietary on-premises software developed in-house or purchased years ago is:

facing slow performance coupled with numerous update and support issues

incompatible with new features due to the outdated and unsupported tech stack

incomplete necessary functionality, even after upgrades (multilingual, mobile, etc.)

non-compliant with corporate policies and procedures (user privacy, security, accessibility, etc.)

your company is forced to utilize different systems and spreadsheets, resulting in:

a time-consuming manual multiple-step work process prone to human errors

a headache collecting, managing, and deciphering the data from disparate sources

holding back the system from advancing to the next level as your numbers are growing each year

the absence of ownership of adaptable all-in-one software with the opportunity to sell it to other organizations

3
3. Migrate to .NET Core

With precision, we handle the migration to .NET Core, confirming all components align and function harmoniously.

4
4. Post-migration Enhancements

Post-migration, we optimize the code to fully exploit .NET Core's capabilities. To boost overall superior system performance, we enhance database performance and incorporate efficient APIs.

5
5. Front-end Migration

We move from older frameworks, such as AngularJS, to contemporary ones like Angular or React. Our team gradually transitions each component to newer frameworks, maintaining application stability and performance. The final phase involves optimizing with shared services, advanced routing, and the removal of outdated dependencies for a polished upgrade.
