Filip Stojanović
Senior Front-End Developer
I build scalable, performance-driven web applications using React and Next.js, with a strong focus on clean architecture and long-term maintainability.
I started my professional journey in 2013 as a graphic designer and gradually transitioned into frontend development, where design thinking and engineering meet. Over the years, I’ve moved from building marketing websites to developing complex, production-ready web applications with a strong focus on performance, scalability, and long-term maintainability.
Today, I work primarily with React and Next.js, building modern web applications that balance clean architecture, thoughtful UX, and real-world business requirements. I enjoy solving complex problems, working on long-lived products, and collaborating closely with designers, backend engineers, and product teams.
I’m particularly drawn to projects where frontend development plays a critical role in shaping the product, not just the interface.
Outside of work, I enjoy photography, playing acoustic guitar, and staying active at the gym — creative and physical outlets that help me stay focused and inspired.
