Vadym K.

With 8+ years of experience in software development, I've delivered 35+ projects across various industries: fintech, healthtech, energy, industrial, maritime, defense, real estate, asset management, e-commerce, enterprise workplace platforms, and SaaS. I work as a .NET Full Stack Developer, building software, web applications, desktop and Windows applications, backend systems, RESTful APIs, and internal platforms that handle real production load, owning delivery from database design to deployment, release, and ongoing new features after launch.

As a .NET Full Stack Developer, I've built React, Angular, and Next.js on frontend and .NET, Node.js on backend. One example is e-commerce fulfillment, where we integrated barcode scanning, inventory management, and multiple shipping-provider APIs, cutting order processing time by 35% and reducing packing errors close to zero. Another example is real-time monitoring frontends for industrial hardware, built for large-scale infrastructure projects where live data visualization replaced delayed manual checks.

As a SaaS software developer, I build asset and fleet management systems in .NET Core and Angular. One example handled large concurrent asset volumes with automated reporting that saved operations teams over 10 hours per week. I'm also experienced building B2B SaaS suites that covers time-tracking, project management, and CRM, consolidating manual labor-cost tracking into a centralized system with approval workflows, AI-assisted insights, and analytics. I'm also open to legacy platforms and existing code with no documentation and daily production fires, rebuilding them into stable systems with proper code review, sprint planning, improved navigation, and design responsiveness across devices.

I build platforms on ASP.NET Web API, EF Core, PostgreSQL, and Azure that automate complex business workflows end-to-end. One example is a lending and compliance system, where we integrated external CRM, pricing, and compliance services to replace manual data entry, cutting hours of manual processing per case. I'm also experienced modernizing legacy asset management systems and existing code for enterprise and defense clients using ASP.NET MVC, SQL, and Entity Framework, one such rebuild reduced manual reporting time by 70% while enabling real-time tracking and secure handling of sensitive operational data.

I optimize Microsoft SQL Server and PostgreSQL queries on reporting-heavy systems, one example reducing execution times by 60-80%. I'm also experienced designing microservices architectures on Microsoft Azure with automated CI/CD pipelines that cut release time by up to 50% for an enterprise client. Beyond .NET, I work with Python and Node.js for scripting layers, and Git and Docker for containerized, repeatable deployments.
