About me

Alex Coronell profile

As a Full Stack Developer with a strong frontend foundation, I approach web development from a systems perspective. I design and implement end-to-end solutions that connect user experience, application logic, and data architecture into cohesive, scalable platforms. My work spans modern frontend frameworks such as Angular, Astro, React, Svelte, and Next.js, combined with robust backend architectures built with NestJS, Node.js, and Spring Boot.

Beyond implementation, I focus on building applications that are engineered for performance, maintainability, and long-term scalability. I prioritize clean architecture, modular design, and production-ready standards to ensure systems remain adaptable as business requirements evolve. My experience includes developing internal platforms, CRM systems, and business-oriented web applications aligned with measurable operational and commercial objectives.

I also bring a strong emphasis on technical SEO, Core Web Vitals optimization, and performance-driven development. By aligning frontend architecture with search visibility and user experience best practices, I help transform digital platforms into strategic growth assets. My goal is to build technology that not only works efficiently, but directly supports visibility, usability, and sustainable business expansion.
