    Here to assist you as a self-motivated .Net expert with 15+ years of enterprise-grade software development experience. I have worked long enough to learn that the most important value I should make is your satisfaction and that’s the best foundation I can build my business on. That’s why I usually get my hands dirty solving problems that most of the developers avoid facing. I have a solid experience in system design and implemented numerous solutions through ASP.NET Web forms, ASP.NET Web API and ASP.NET MVC, from windows form applications to heavy-duty systems with microservice architecture. With a wealth of experience across industries such as oil and gas, 24/7/365 flow-centric online systems, engineering, procurement and construction, I will bring a passion for delivering robust and reliable solutions to your project.

Such as migrating old .Net framework based product to .Net Core (.Net6) ✅Software products which are made to be able to serve, be maintained and scale for several years. This kind of software usually need high separation of business from technology to be technology-change resilient over time, so they need robust architecture and more design considerations should be made for them. A highlight of my technical specialties: ✅ C#.NET ✅ .Net Framework and .Net Core ✅ Microservices and related technologies and tools such as RabbitMQ, API Gateway, Identity Server... ✅ Frontend technologies and tools: MVC, JQuery, HTML, CSS, Javascript, AJAX, WPF and familiar with MAUI ✅ Web services development and integration, Soap, RESTful APIs and Swagger ✅Entity Framework and Entity Framework Core, code first or database first ✅ Database design, Microsoft Sql server and also familiar with OLAP, analysis service and integration services.

    Main specialization – C++ (STL/MFC, QT, PostgreSQL - on board). 15+ years of experience. Open to start new project on following tech stack: 1. Web: Python (any web framework), React, React-Admin, PostgreSQL, Dockers, Amazon Web Services, FreeSwitch. 2. Desktop, client/server solutions: C++, QT Framework. Last few years work with C++ on Debian (PostgreSQL, ncurses, thermal printer). Recently extensively switched to QT framework (Music Score scanning software). Had a chance to use general logic experience to lead engagement projects in completely unknown for me areas like Lotus Notes/Domino, software for greenhouse heating systems construction, some projects on Delphi. Searching clients for cooperation to outsource software products development. My formula: Scope of Work – Time – Budget (W-T-B). W-T-B key principles: - establish project required development process; - define milestones; - provide “access points” for process control from a client side; - self-documented code; - quality assurance; - support.
