About me :)
Design Philosophy
I am a product designer who creates simple yet elegant products for users by leveraging my previous mechanical engineering background to provide a more rigorously analyzed, user-centered, functional experience. I believe that focusing on the needs and desires of users, as opposed to designing for a solution, will create the most effective pathways for improving the quality of life of all living beings across the world.
Design Experience
Currently, I am contracting with Oxy, working directly with their CEO and Design Lead Anthony Ferrera. In my spare time, I also volunteer at Hack For LA, working on their Expunge Assist project as a UX Design Co-lead.
I’ve had the opportunity to work with Savviest (now acquired by PAIRIN) as a contracted designer, and have volunteered at HackForLA as a UX designer. Most recently, I interned at Oxy, an Arizona-based design agency, working on full-process design from research to ideation to high fidelity designs.
As a side hustle, I’ve designed and sold over a thousand products as a solo designer on eBay, juggling the entire process including designing with Solidworks, manufacturing using 3D printing, managing inventory, and packaging/distributing the end product.
Education
I have a Springboard UI/UX Design Certification with over 700 hours of hands-on coursework involving design skills such as research, synthesis, information architecture, wireframing and prototyping, UI principles and heuristics, and more.
I also graduated with a Master of Science in Mechanical Engineering from Carnegie Mellon University along with a Bachelor of Science in Mechanical Engineering and a minor in Design (also from CMU). As mechanical engineering and UX design have similar thinking processes and design methodologies, I pivoted to UX, feeling that it was more connected with the end user and that my previous experiences could bolster my new path.
Extracurricular Activities
When I’m not ideating ways to actively scale the impact of my next project, I enjoy hanging out with friends and finding new restaurants to eat at , as well as play tennis and watch Formula1. I also dabble in competitive multiplayer activities such as Valorant (Diamond 3 peak), Counter-Strike: Global Offensive (MGE peak), and League of Legends (Plat - Emerald) - all of which have enhanced my skill in collaborating and cooperating with strangers and team members as well as my ability to work and adapt under pressure. I also like to listen to various genres of music, such as pop, alternative, EDM, rap, kpop, jpop, R&B, and French rap.
