Nikolas K.
.NET, Web & AI/ML Engineer
20+ years building web software & applied AI
I am a .NET and web developer with 20 years of commercial experience, from web portals and CRM/ERP integrations to modern ASP.NET Core applications. I hold a Master’s degree in Biomedical Computer Systems from Kharkiv National University of Radioelectronics.
Experience & Approach
My core work spans C#, ASP.NET MVC and Web API, ASP.NET Core, Angular, JavaScript, SignalR, and MySQL. I design maintainable portals, APIs, user interfaces, and data-backed business systems.
Selected work includes an insurance web portal built with ASP.NET Core, SignalR, Angular and MySQL; a healthcare portal using SignalR and WebRTC; a call-centre management system; and CRM/ERP integrations for a major Ukrainian electronics retailer.
I complement production web experience with applied AI/ML training in TensorFlow, natural-language processing, computer vision, time-series prediction, machine learning, and Big Data analysis using Python.
