What It’s Like to Work with Me
About Me
I am a Product Designer with over 4 years of experience, driven by the challenge of discovering unobvious user problems and building complex systems.
My unique approach combines system thinking with empathetic design, transforming complex ideas into intuitive, result-driven experiences. I specialize in deep analytical user research and rapid iteration, consistently delivering solutions that delight users and drive business growth.
I use my strong communication skills to ensure effective cross-functional teamwork.
I thrive in fast-paced, innovative environments that offer high autonomy, where I can contribute to products that genuinely relieve user pains and improve lives.
My desire to share and help others led me to begin mentoring last year. This experience constantly proves how easily we misunderstand each other, and that true connection with students is built through empathy, logical reasoning, and shared basic knowledge.
Outside of work, you’ll find me reading with my book club, playing tennis very inconsistently, winning at decoding strategy board games, or documenting tiny moments through phone photography.
