Software Engineer

About

I'm an undergraduate at UC Berkeley studying Electrical Engineering & Computer Science. I'm interested in software engineering and backend systems.

I enjoy building systems that are technically sound but also helpful for people. Most of my projects involve some mix of full-stack development, data organization, and clean system design.

Currently, I'm a Software Engineering Intern at Maadhev LLC, where I'm building a custom ACH payment system and Shopify integrations. I previously interned at iPick.ai, where I built a graph-based platform that visualizes relationships between thousands of companies, and at Claythis, where I worked on their AI-driven 3D model generation technology.

Experience

Software Engineering Intern

Maadhev LLC

May 2026 - Present

Cupertino, CA

  • Built a custom ACH payment system (Python, Flask, Stripe API) integrated with a Shopify app, enabling bank transfer payments at 70% lower per-transaction cost than card processing.
  • Engineered Stripe webhook handlers to sync payment and fulfillment data between Stripe and Shopify in real time, automating order confirmation across 50+ transactions.
  • Rebuilt the Shopify storefront and checkout flow, consolidating a multi step checkout into a single page.

Software Engineering Intern

iPick.ai

Jan 2026 - May 2026

Berkeley, CA

  • Architected a graph-based company relationship visualizer using React, D3.js, and PostgreSQL.
  • Built a supplier/subsidiary relationship extraction pipeline across 5,000+ public company tickers, storing structured supplier/subsidiary edges in PostgreSQL to power graph-based visualization in the frontend.
  • Integrated the Anthropic API to generate real-time news summaries, enriching company profiles with live information.

Software Engineering Intern

Claythis

May 2025 - Aug 2025

San Mateo, CA

  • Created a Unity-based game in C# showcasing Claythis's AI-driven 3D model generation pipeline, implementing core weapon & health systems such as reloading, recoil, animations, armor, and healing.
  • Tested and validated integration of the AI-generated 3D character models into Unity, verifying rigging, animation, and rendering behavior across the pipeline's outputs.

Hobbies

Spotify

The best way I can describe my music taste is “I like what I like.”

Valorant

If I'm not playing sports, I'm probably playing video games with my friends. We play Valorant most often. We're lowkey terrible, but that's beside the point.

Current rank

Soccer & FC Barcelona

I've loved soccer since I was 4 and I played competitively until college. I was captain of both my club team and high school varsity team, made the all league first team all 4 years of high school, and finished with 45 goals and 20 assists over 4 years. You can still find me playing pickup or intramural games :)

I've been a Barça fan since age 4 because of my older brother. I catch most of their games, and honestly my mood heavily depends on the result. (jk… mostly.)
