I'm a Software Engineering Manager and Full-Stack Software Engineer with 7+ years of professional experience designing, developing, and delivering scalable business applications, SaaS platforms, CRM/ERP systems, and enterprise web solutions.

My primary engineering track is C# / .NET / ASP.NET Core, with strong hands-on experience in REST APIs, PostgreSQL, relational database design, Clean Architecture, multi-tenant systems, authentication/authorization, cloud deployment, and CI/CD.

On the frontend and modern full-stack side, I work with React, Next.js, TypeScript, Angular, Tailwind CSS, Supabase, and Neon PostgreSQL.

I also have experience integrating AI/LLM capabilities into SaaS applications, including AI-assisted business workflows, intelligent assistants, and API-based LLM integrations.

I have worked remotely with an international UK-based client on RAMS-APP, a risk assessment and safety-management platform, collaborating across distributed development workflows and communicating directly around requirements, implementation, delivery, and production support.

This experience strengthened my ability to work effectively with remote teams, international stakeholders, business requirements, cloud services, third-party integrations, and production-oriented software delivery.

Engineering philosophy: Build reliable software through clear architecture, maintainable code, practical engineering, and collaborative teamwork.
