Hey 👋🏾 I'm Justin. I'm a software engineer and experience designer, driven by the intersection of technology, human-centered design, and first-principle based solutions.

I'm fueled by curiosity and commitment to continuous learning. At Google, I work on problems that are aligned with the goals for Maps and how our information needs (currently, food 🥘) are met.

I enjoy challenges that blend technology and process in traditionally non-technical domains to create novel solutions.

I believe in the power of empathy-driven design at the base of the user experience. Beyond my professional work, I am passionate about improving tech accessibility in my community. Let's connect and explore how we can innovate together.
