Computer Science @ Harvey Mudd • Data Analytics + Full-Stack Builder • Student-Athlete

I’m a Computer Science student at Harvey Mudd College (Class of 2027) focused on data analytics, full-stack product development, and building tools that turn raw information into decisions. I’ve shipped dashboards and scheduling tools, and I’m currently extending a real project from a V1 prototype into a V2 with SQL-backed analytics.

Languages: Python, Java, C++, JavaScript, Racket • Web: React, Next.js, Tailwind CSS • Data: PostgreSQL (learning), SQL (in progress) • APIs: Google Sheets API, OpenAI API • Tools: Git

A lot of organizations have the data they need — but it’s scattered, unstructured, and difficult to query. Reporting becomes manual, dashboards become fragile, and insights arrive too late.

I build systems that fix that by:

• Turning messy sources into clean dashboards and role-based views
• Designing workflows that keep data structured, auditable, and updatable
• Automating repetitive analysis and writing using AI, while keeping outputs controlled
• Shipping software like a real team: branches, PRs, review-ready commits

I’m currently pursuing data analytics / analytics engineering / data science internships where I can:

• Work with real datasets (messy, multi-source, changing)
• Build dashboards and reporting pipelines that drive decisions
• Combine analysis + engineering (not just notebooks)
• Learn fast, iterate with feedback, and ship production-quality work

September 2025 – December 2025 • Claremont, CA

Developed responsive dashboards and scheduling tools for athletes and coaches, collaborating on backend API design and database integration.

Highlights

• Built scalable UI components with React + Next.js
• Collaborated on API/data integration using Spring Boot + PostgreSQL
• Implemented real-time updates and clean end-to-end data flow

August 2025 – Present

Collaborating on a scheduling platform that integrates academic course catalogs with athletic practice schedules to detect conflicts and streamline planning.

What I’m building

• Responsive calendar UI, course search/filters, role-based dashboards
• Frontend development in React / Next.js
• Iteration with real stakeholders (athletes/coaches/admins)

Summer 2025

Built a full-stack dashboard that uses Google Sheets as a live backend for Duke basketball game data, and generates structured content automatically.

Highlights

• Next.js + TypeScript + Tailwind CSS
• Google Sheets API as the live datastore (read/write)
• OpenAI API to generate structured:
  • game recaps
  • tweets
  • hashtags
• Secure server-side actions to write outputs back to the data source

I’m currently building a V2 of BlueDevils Digest that keeps V1 intact and adds modern UI, filters, SQL, analytics, and improved AI narrative generation.

What makes this a real engineering project

• V1 stays untouched as the original shipped build
• V2 lives in separate folders and is developed incrementally via milestone branches + PRs
• Each milestone is reviewable, testable, and documented like a production workflow

V2 areas I’m actively working in

• app/dashboard_v2/ (new dashboard UI)
• lib/metrics/ (analytics + computed values)
• lib/filters/ (filter logic + state)
• lib/db/ + prisma/ (SQL-backed data layer)
• scripts/syncSheetsToDb.ts (pipeline: Sheets → DB)

V1 used Google Sheets as the “source of truth.” V2 upgrades the data layer so the dashboard can support:

• More flexible querying for analytics
• Cleaner derived metrics
• A foundation for repeatable reporting as the dataset grows

Co-founder & Full-Stack Developer • August 2024 – Present

Designing and developing a fantasy platform for trading athletes like stocks.

• Built pricing algorithms combining performance + engagement metrics
• Focused on dynamic, market-style valuations that update over time

August 2025 – Present

Tutoring and grading for data structures and algorithms.

• Tutoring ~50 students individually and in groups
• Feedback on syntax, efficiency, documentation, and problem-solving approach

• Python, Java, C++, JavaScript, Racket
• HTML, CSS
• SQL (in progress)

• React, Next.js
• Tailwind CSS

• PostgreSQL (learning through V2 migration work)
• Spring Boot (collaborative work)
• Google Sheets API (V1 datastore + sync source)

• OpenAI API
• Git
