What I'm looking for

I seek roles building scalable, secure multi-tenant SaaS systems where I can lead backend architecture, automate operational workflows, and apply AI-assisted development.

I am a .NET developer focused on building and maintaining production systems from domain modeling to VPS deployment with Docker, specializing in multi-tenant SaaS platforms and ASP.NET Core APIs using Clean Architecture. I integrate automation tools like n8n and use AI as a structured development assistant to accelerate delivery without sacrificing architecture.

As Lead Developer at NeoDogma and FlowHub, I have delivered systems used in production — including an educational platform serving ~500 students and a multi-tenant backend for CRM and document signature services. My work includes PostgreSQL multi-schema designs, EF Core, JWT-based auth, and deployment with Docker, Nginx, and Traefik.

I author technical articles on ASP.NET Core security and maintain a technical blog; I value robust domain separation, secure multi-tenant data isolation, and pragmatic automation to streamline operational processes.
