About
Specialized in modern JavaScript ecosystems
I specialize in building end-to-end web applications using cutting-edge technologies like React, Next.js, NestJS, and TypeScript. My approach combines clean, maintainable code with performance optimization, resulting in applications that scale efficiently and deliver exceptional user experiences.
I've helped startups reduce deployment time by 60% and enterprises improve application performance by 40% through strategic architecture decisions and modern development practices.
Currently, I'm a Senior Full-Stack Developer specializing in accessibility and performance optimization. I contribute to the creation and maintenance of scalable applications that meet modern web standards and best practices to deliver inclusive user experiences.
When I'm not coding, you'll find me exploring new coffee brewing techniques – precision matters in both code and coffee.
