Hi, my name is Vitalii.
I’m a Full-Stack .NET & Angular Developer with 6 years of experience. From architecture and database design to deployment on Azure and Docker, often as the only developer on the product.
From idea to production
ASP.NET Core services, public APIs, background jobs on Hangfire, real-time updates with SignalR and fast SQL on MS SQL or PostgreSQL.
Angular and Blazor interfaces built to the design, from Excel-like tables to accessible booking flows tested with a screen reader.
Multi-tenant products with Stripe subscriptions, workflow automation and integrations like Twilio, Google Calendar and OpenAI.
Where I’ve been
Built three SaaS products with paying customers: CRMs for service and real estate businesses and a platform for AI voice agents. Designed a custom job queue on PostgreSQL, a workflow engine, a public API and a multi-tenant CRM on Angular and .NET with Stripe and Hangfire.
Made a B2C airline booking site fully WCAG-accessible, built an AI document calculator on Blazor and the OpenAI API as the only developer, and shipped Mapbox features in a .NET MAUI social app.
Built an Excel-like table component in Angular, cut an analytics query from 45 to 2 seconds in a booking platform, and developed Azure Functions for a large enterprise project.
