About me
With over 6 years of experience in full-stack web development, I am a software engineer focused on the architecture of high-performing, scalable applications. My expertise spans both frontend and backend technologies, with a solid foundation in the front-end stack (JavaScript, HTML, CSS) and an extensive understanding of modern frameworks, libraries, and tools that drive seamless user experiences.
I specialize in bridging the gap between data/APIs and UI/UX design, building user-friendly, responsive, and accessible products. My experience enables me to design and implement both client-side and server-side solutions, from crafting intuitive user interfaces to architecting robust backend systems. I am proficient in modern JavaScript frameworks like React and Node.js, and I'm adept at integrating them to build cohesive, efficient applications.
My focus is on system design, code quality, and performance optimization throughout the development lifecycle. I am experienced in leading projects from concept to deployment, ensuring that the entire application stack is aligned with best practices for scalability, maintainability, and ease of integration.
