What I'm looking for

I seek roles building user-centered, scalable web products in collaborative teams, owning architecture, product quality, and end-to-end delivery.

I am a product-minded Full-Stack Engineer specializing in the TypeScript ecosystem, focused on building reliable, performant web applications with seamless user experiences. I leverage Next.js, Node.js, and React to deliver production-ready solutions.

Recently, I independently architected, built, and launched SubGuard, a monetized SaaS platform, owning database and API design through global payment integration and deployment. I apply solid architectural principles from my .NET background to ensure maintainable systems.

In professional roles I have implemented domain-driven design, EAV data models, and RBAC, and I have improved API response times and reduced issue resolution delays. I collaborate effectively in both remote and in-office teams and use AI tools to accelerate development and maintain high code quality.

I seek to continuously deliver user-centered products, write well-tested code, and contribute to scalable architectures while mentoring peers and improving engineering processes.
