Growing up I've lived in a small city called Tracy for the majority of my life, and I'm now currently a 3rd year at UC Berkeley studying Computer Science with a minor in Data Science! Prior to college I had actually never written a line of code in my life...

The summer before my freshman year at Berkeley, I learned how to program by going over the CS61A content in advance—Berkeley's introductory CS course I would take in the Fall—and that's where I fell in love with programming. Since then, I've worked at a number of dope startups as both an intern and founding engineer in areas like the backend, frontend, fullstack, AI, mobile apps, etc., and will be tackling big tech this upcoming summer at Adobe in Seattle as a software engineering intern!

I also quite like cats, I have two named Pucca and Baki. There are some pictures below of them :)

I love meeting new people and making new connections, so don't hesitate to reach out if you have any questions or would like to chat!

Solace
Aug 2025 — Present

Founding Engineer

At Solace, I'm currently working as a founding engineer and built a lot of what Solace is today from the ground up. Our sole mission is to make mental wellness more accessible, and we're doing so through leveraging AI/ML to build both hardware and software AI wellness agents. I worked on Solace's core infrastructure, the core voice-to-voice and hyper-personilization functionality of the AI agents, amongst some other cool features.

EduSync
Jun 2025 — Aug 2025

Software Engineer Intern

EduSync is a startup aiming to bring AI to education starting from a young age. I worked on entirely refactoring the RAG system, a bunch of AI-based features for teachers and students to familiarize themselves with AI in the classroom, amongst a lot of other optimizations. Some of the features I built and shipped from 0->100 include AI-based PowerPoint/rubric/assignment feedback generators, a weekly pulse report feature for parents, and more.

SuperIntro
Nov 2024 — Jan 2025

Software Engineer Intern

SuperIntro is an AI-based social networking platform and relationship simulator. I worked primarily on the backend; some examples include how I updated event RSVP system with TypeScript + MongoDB for match-based invitations and notifications, built and prompted conversational AI agents with LangChain automating 120+ simulated interactions per day, and generated successful matchmaking in 92% of registered SuperIntro users across SF/LA/NYC.

Extracurriculars

Besides my professional experience, I've also been involved in a few other things around campus. I've done some tutoring (CS61A, CS61B/Data Structures and Algorithms), and participated as a team member in a few different tech clubs where I worked on things ranging from software applications all the way to rocketry.
