What I'm looking for
I'm a Fullstack Developer and Product Designer with over four years of experience in delivering high-impact digital products. My journey has been marked by a proven record of shipping scalable solutions and redesigning complex systems, particularly for growth-stage startups and established companies. I thrive on elevating user experiences and have successfully driven end-to-end development for digital suites serving hundreds of thousands of users.
At Blue Book Inc., I was the sole UI/UX designer and lead developer, where I designed and implemented a new marketplace that transformed user engagement. My efforts in engineering a new search experience significantly improved user discoverability. I have been recognized for my design quality and product vision, consistently delivering across both design and technical roles.
My experience also includes working with early-stage AI SaaS startups, where I contributed to shaping product direction and enhancing client onboarding through rapid iterations. I am passionate about creating seamless user experiences and have a strong foundation in both frontend and backend development, utilizing technologies such as Vue.js, NestJS, and Laravel.
