Featured Work

Systems I've Built

Experience-backed engineering work and selected personal projects across mobile, AI tooling, full-stack apps, and controls.

01

AI Competition Platform

Infrastructure for UCLA's AI Agent Gaming Tournament

  • MCP-based AI competition platform with pluggable runtime adapters and a unified agent API across heterogeneous games.
  • Built the first non-OpenSpiel runtime by integrating Pokémon Showdown with FastAPI, poke-env, Docker, and WebSockets.
  • Designed deterministic 12-pick drafting backed by a versioned 72-Pokémon catalog for reproducible evaluation.
  • Hardened the Pokémon runtime with approximately 290 automated tests covering lifecycles, drafting, stale actions, failures, and backend results.

02

Realy

Multi-table AI reasoning agent

  • Contributed to an AI-powered data analysis system for querying multiple datasets through natural language with traceable table transformations.
  • Built observability for a LangGraph table-reasoning agent by propagating structured tool/runtime failures into Supabase incident workflows.
  • Supported admin debugging with correlation IDs, error classification, and LangSmith trace links across runtime streams.
  • Re-architected multi-turn state management to reconstruct agent state from durable messages and table metadata without persistent checkpoints.

06

Marble Quest

Personal C++ game

  • Developed a modular C++ game with systems for health, lives, ammunition, scoring, levels, collectibles, and player progression using object-oriented design.
  • Implemented multiple enemy types with distinct AI behaviors and factory-based spawning, alongside projectile interactions, movable marbles, puzzles, collectibles, and level progression.

Experience

Engineering Timeline

Production software, research infrastructure, mobile development, and hardware-integrated systems.

Lead Android Engineer

Leechy

Leading Android engineering for Leechy's production marketplace, owning the Kotlin/Jetpack Compose app from architecture through Google Play releases.

  • Architected and built a roughly 135K-line Android application with layered MVVM, coroutine-driven async flows, and Supabase-backed data access.
  • Engineered rental and service workflows across bookings, payments, delivery, handoff verification, condition tracking, messaging, and availability.
  • Built geospatial discovery with Mapbox, dynamic clustering, and Google Places, plus Stripe Payment Sheet, Connect, and Identity integrations.

Undergraduate Researcher

Trustworthy AI Lab at UCLA

Building AI-agent infrastructure across autonomous-game evaluation and multi-table reasoning systems.

  • Architected MCP-based competition infrastructure with pluggable runtime adapters and a unified agent API.
  • Integrated Pokémon Showdown using FastAPI, poke-env, Docker, and WebSockets while preserving the agent-facing MCP interface.
  • Built Realy observability across LangGraph runtime streams, Supabase incident tracking, error classification, correlation IDs, and LangSmith trace links.

Controls Lead / Electrical Ground Support Equipment Lead

Rocket Project at UCLA

Led controls and ground-support software for liquid rocket propulsion testing, spanning embedded systems, simulations, telemetry, and hotfire validation.

  • Led development and hotfire validation of Rocket Project's first successful closed-loop liquid rocket engine throttling system.
  • Integrated embedded C++ PID control, custom actuated valves, pressure feedback, and fault detection/recovery.
  • Designed and validated valve hardware, then tuned controllers through simulation, HIL, waterflow, and coldflow testing to achieve sub-0.7 s setpoint settling.

Mobile Developer Lead

Creative Labs at UCLA

Led mobile development for a gamified coding education app, coordinating implementation across product design, frontend features, and backend integration.

  • Led a 3-developer team building a React Native app for coding problems, rankings, progression, and in-app currency.
  • Translated Figma designs into interactive mobile features and polished app flows.
  • Owned frontend features from design handoff through backend integration while collaborating with designers and engineers to integrate REST APIs and debug cross-stack issues.
