Hey there! I'm a Frontend Developer with 6+ years of experience building scalable, high-performance web applications using React, JavaScript, and modern frontend technologies.

I enjoy turning complex business requirements into intuitive, responsive user experiences while maintaining clean, maintainable, and performant code. Throughout my career, I've worked closely with product, design, and engineering teams to deliver solutions that create measurable business value.

I take ownership beyond implementation; thinking about user experience, performance, scalability, and long-term product success. I'm passionate about solving real-world problems through technology and contributing to teams that value collaboration, innovation, and continuous improvement.

Currently open to exploring new opportunities where I can help build impactful products and continue growing as an engineer.
