What I'm looking for

I seek a frontend role focused on performance, scalable component systems, and opportunities to apply ML insights while mentoring and growing technically.

I am a frontend developer focused on building high-performance React applications that deliver seamless user experiences and maintainable code. I couple a strong frontend engineering practice with a machine learning background to create intelligent, performant solutions.

At PT. Infosys Solusi Terpadu I implemented a reusable component system that sped development by 40% and improved interface consistency by 35%, optimized initial rendering with lazy loading and code splitting to reduce load times by 25%, and drove 90% unit test coverage to reduce bugs by 18%.

I served as a machine learning mentor and cohort lead at Bangkit Academy and Dicoding Indonesia, guiding students, achieving top distinctions, and contributing to high graduation and project success rates. I led capstone development, integrated 25+ APIs, and implemented data sync strategies that reduced data errors by 60%.

I bring strong skills across React, Next.js, TypeScript, testing, and modern CSS frameworks, plus hands-on experience applying TensorFlow and NLP models. I seek roles where I can drive product quality, performance, and user-centric features while mentoring others and continuing to grow technical depth.
