Let’s talk

In 2017 we got a request from Medikit, a healthcare tech startup, to build a digital healthcare ecosystem of medical interactions between doctors, patients, pharmaceutical and insurance companies. It was huge and required well-thought system architecture to serve millions of users and process billions of records. In addition to ASP.NET Web API, ASP.NET MVC and React we used a blockchain technology to control access to health records. It took us a couple of months to deliver a beta version. Currently we are expanding the system, adding new modules and features while supporting existing ones.

One more amazing customer’s success story started in 2014. Back then, it was an ambitious idea to build a solid and powerful e-Procurement and e-Sourcing Platform, which turned to the award-winning software used worldwide including the European Union, Canada, Australia, Japan, China, Singapore, and the United States. Abto Software has been responsible for the development and maintenance of the whole suite of e-Procurement and e-Sourcing software products since the very beginning.


Our client is a European provider of e-Procurement and e-Sourcing solutions.


  • Adopt-state-of-the-arttechnologies
  • Focus on the high quality of services provided by the e-Procurement and e-Sourcing platform
  • Retain existing customers by expanding the set of features provided by the platform

  • The developed cloud platform offers a broad range of e-Procurement and e-Sourcing solutions that meets the needs of both private and public organizations
  • E-Sourcing tool ensuring. Transparent supplier selection through 4 steps: submitting e-Request through intuitive eRFx tool for proposals (RFP), information (RFI), quotations (RFQ), and tenders (RFT); inviting suppliers for reverse and forward e-Auctions; comparing received quotas with adjustable evaluation tools and custom reports; choosing the right supplier
  • Supplier Master Data Management (SMDM) enables creating and maintaining a strong supplier base
  • Supplier Onboarding is part of the comprehensive Supplier Master Data Management solution. It gives companies complete toolset to evaluate, register, and communicate with the suppliers

Medikit, a healthcare tech startup, launched in 2017. Aims at building a digital healthcare ecosystem of medical interaction between patients, doctors, pharmaceutical and insurance companies offering value-based patient-centric healthcare.


  • Security risks to patient data: the healthcare industry has more data breaches than any other sector and medical records are being stolen and passed on
  • Lack of transparency: patients have no immediate access to health records written by medical professionals; medical professionals are only able to share data quickly within their own organization or with other health professionals using the same EHR system
  • Integration with the national ehealth system: the software will work in all the governmental clinics and medical institutions, serving millions of users


.NETASP.NETASP.NET MVCASP.NET WebAPIblockchaindigital healthehealthHyperledgerMVCtelemedicine


  • Our team delivered a few modules with the functionality listed below
  • Telemedicine, an online consultation with a doctor and patient using a webcam interface, is set to be the future of consultations
  • Electronic Healthcare Records (EHR):
    by implementing EHR, patient data can be tracked over an extended period of time by multiple healthcare providers. The blockchain-based EHR we have developed puts full control over the health data in the patient’s hands
  • Online Appointment offers the opportunity to book medical appointments electronically in medical institutions or online. When selecting a physician, a patient can make an informed decision about a doctor based on recommendations from both fellow patients and other doctors
  • Doctor’s Account: by leveraging an integrated platform, the family practitioners and other doctors can nurture ongoing patient relationships to keep patients on a path toward better health
  • House Call: a patient can request an onsite consultation with licensed, qualified doctors

Scenario #3:

You have a solution already, but want IT to work better

You see that your software isn’t reliable enough and can do a better job? You are not satisfied with the results and you waste too much time and effort to make features happen? Hold on! Along with web, mobile and desktop applications engineering using .NET stack, we solve the problem of technology modernization, cross-platform migration, application integration with 3rd parties, or even migrating from a legacy to more modern technologies and business environments. We also help with porting .NET Framework apps to powerful ASP.NET MVC and ASP.NET Web API based on .NET Core.

We’ll tell you more

For instance, Abto software engineers migrated the legacy ERP system to cloud with web and mobile interfaces for the US retail company, enabling the retailers and sellers to maximize profits and significantly improve business process and collaboration between customers, suppliers, and distributors.

Also, we’ve helped US based Public Corporation with VB6 to WPF Migration to decrease the software license costs for 75% of their users. Technically speaking, we reimplemented slow AutoCAD procedures in a much faster C# variant – and voila!


The project team is well underway to transforming client’s ERP software modules into one orderly system with one UI/UX and development standard, fewer discrepancies, code duplication and ongoing maintenance required.


  • The ability to run on any web platform or device
  • Run as cloud ERP to meet market needs
  • Introduce secure Public API
  • Seamlessly connect the new UI
  • Be secure, stable as to lower support and maintenance costs


.NETASP.NET MVCBootstrapC#CSSEntityFrameworkERPHTMLJavaScriptjQueryMS SQL ServerTableauTypeScript


  • The flexible modern architecture of the ERP is designed to be able to handle users using web/mobile/desktop clients, secure access ERP data using Public API; easy to develop new ERP modules and integrations
  • The new UI/UX simplified the workflow for its users, unified UI of all
  • The comprehensive web ERP is able to handle thousands of new users as a company continues to grow


Our client is a world’s leading manufacturer in their area. The request was to build a single state-of-the-art tool that would be able to design all types of products.


We embarked with a complete revamp of the first tool – an AutoCAD plugin written partially in VBA, partially in LISP. It had problems during installation, each new version of AutoCAD brought new issues for the plugin. Some parts of the functionality stopped working completely. VBA is still supported in AutoCAD, but it is not available by default and requires a separate download and installation.

The project was finished on time and within budget and successfully released to the client. New program automated common routines, fixed issues present in the old plugin, significantly speed up the process of designing new profiles, allowed usage by less experienced users. There were made savings on license costs for 75% of users as the standalone application doesn’t require AutoCAD.

To outsource or not to outsource, that is the

Is your software a core value proposition, or it’s a vehicle to solve users’ problems? Is your solution designed for technical people, or non-technical users? Is your product intended to make a revolution in the world of tech, or it is simply aimed at solving a specific business need? If all your answers drift toward the second part, then software outsourcing should be a decent option for you.
