What I'm looking for

I seek a senior front-end role focusing on Angular, collaborative teams, impactful products, mentorship, and opportunities for architecture and performance improvements.

I am an experienced web developer specializing in Angular front-end development, TypeScript, and modern web architectures. I focus on building responsive, high-performance user interfaces and integrating RESTful APIs and real-time services.

As a lead developer I architected and delivered large microservice e-commerce platforms, Angular CSR/SSR showcases, and admin CMSs, reducing time-to-market and improving performance and customer conversion rates.

I have a strong full-stack background with experience in Node/Nest, microservices, NGINX, Docker, and DevOps practices, and I regularly collaborate with designers and stakeholders to turn designs into production-ready interfaces.

I value mentorship, code quality, and continuous learning, and I bring practical experience in multi-tenant, multi-language systems, real-time dashboards, and hybrid mobile WKWebView apps that increase product visibility.
