I am a Senior Software Developer with 10 years of experience building high-performance desktop and web applications using the .NET ecosystem.
My core expertise is in WPF development (9 years), where I have delivered enterprise-grade and real-time applications, extensively using DevExpress for WPF (advanced grids, charts, dashboards, custom UI components, and performance optimization using MVVM).
I also have 2 years of experience with Blazor WebAssembly, building modern, component-based web applications, and 1 year of experience with ASP.NET Core Web API and .NET Aspire for developing and orchestrating scalable backend services.
I bring strong trading and financial domain knowledge, having worked on real-time systems involving live market data, high-frequency updates, and low-latency UI rendering — where accuracy, performance, and stability are critical.
I follow Test-Driven Development (TDD) and focus on:
Clean, maintainable architecture
Testable and scalable code
Reliable and predictable delivery

Most teams don't struggle to find developers. They struggle to find someone who can own architecture decisions, hold engineering standards, and still get hands-on when it matters. That's the role I've filled for over 10 years.
I specialize in .NET Core and C# backend systems — designing REST APIs, building microservices, and architecting enterprise-grade platforms end to end. On the front end I work across Angular and React. Cloud deployments across Azure and AWS, CI/CD pipelines, and Agile delivery are all part of my regular workflow.
On Upwork: Top Rated Plus, 100% Job Success Score, 50+ completed contracts, 12,000+ hours billed — mostly with US-based product teams that needed a senior engineer they could trust to own the technical side.
I take on both long-term engagements and focused consulting work. If you have a complex backend challenge or need a technical lead who can bridge engineering and business — let's talk.
