Viktor Chernysh

Hi, I'm Viktor Chernysh. I created this website primarily as my web resume and portfolio. It’s still a work in progress, and I’ll soon be expanding it into a blog where I plan to share insights on developer-focused security and the efficient use of technologies in terms of cost and performance.

I am an experienced Full Stack C# .NET Developer with over 12 years of expertise in architecting, implementing, and maintaining enterprise-grade web applications, services, and microservices built on the .NET platform.

My expertise spans architecture design, backend and frontend development, and the full software development lifecycle for enterprise-level solutions.

The majority of my enterprise experience was gained at Cardinal Intellectual Property, where I architected and developed Azure-based microservice applications that supported scalable, high-performance systems. That role demanded deep technical precision, modular design thinking, and close collaboration across teams.

I have a proven track record of building scalable, production-grade applications and delivering robust support across the full lifecycle. My approach combines semantic clarity, pixel-perfect UI/UX, and blueprint-driven modularity to ensure maintainable, future-proof solutions.

I’m methodical, exacting, and deeply invested in both technical and creative excellence. If you're building something that demands precision, scalability, and standout design—I'm ready to help you make it real.
