About

With over 13 years of experience in developing and delivering complex, high-performance web applications, I specialize in building scalable and maintainable solutions based on modern JavaScript and TypeScript frameworks. My background covers the full spectrum of web development — from designing intuitive, responsive user interfaces to architecting robust backend systems and optimizing cloud deployments. Throughout my career, I’ve worked with a wide range of technologies, frameworks, and third-party services. My core expertise lies in frontend development, where I’ve led the design and implementation of rich user experiences using frameworks like React, Angular, and Vue. On the backend, I have solid experience with Node.js, Express, and various databases (SQL and NoSQL). I’m passionate about writing clean, maintainable code, adopting best practices, and continuously improving technical processes. In recent years, my focus has also included leadership and people management. I’ve built and led cross-functional teams, provided technical mentorship, and contributed to talent acquisition by conducting interviews and making staffing decisions. My leadership approach emphasizes collaboration, knowledge sharing, and helping team members reach their full potential.
