I'm an aspiring full-stack or backend engineer interested in building scalable systems and solving real-world problems through thoughtful engineering.

At Vassar, I contributed to a research project on improving Go’s concurrency model, where I developed ParV2, a prototype abstraction for safer, more expressive parallelism in Go. This experience strengthened my foundation in systems-level programming and language design.

I also built FitTrack AI, a full-stack fitness platform that generates adaptive half-marathon training plans using GPT-4o and real-time user data. The app integrates LLM feedback loops, GPS visualization, and Strava sync to enhance user motivation and performance.

Whether in research or deployment, I focus on clean architecture, cross-functional collaboration, and learning fast in high-impact environments.

## Work Experience
### Software Engineer Apprentice @ Coding Temple
Jan 2025 – Present
- Built an e-commerce web app using React (TypeScript), Redux Toolkit, and Auth0, enabling secure login and personalized cart functionality across sessions.
- Implemented product and category fetching with React Query and FakeStoreAPI, providing real-time data updates with optimized caching and background sync.
- Developed backend services with Flask and SQLAlchemy, connected to MySQL, supporting complete CRUD operations and structured database design.
- Designed and implemented a service management backend system using Flask, Marshmallow, and PostgreSQL, featuring JWT authentication, role-based access control, and RESTful APIs for mechanics, inventory, and service tickets.
- Deployed both applications using Vercel and Render, maintaining GitHub workflows with branches, commits, and pull requests to simulate CI/CD pipelines.
- Practiced agile development and version control, contributing to scalable, production-ready codebases in a remote training environment.

### Research Assistant @ Vassar College
Jan 2024 – Jan 2025 | Poughkeepsie, New York, United States
- Designed and implemented ParV2, a concurrency abstraction in Go that leverages reflection to run arbitrary functions in parallel with runtime safety.
- Delivered a PAR composition operator inspired by CSP/Occam, laying the groundwork for more expressive and less error-prone concurrent programming in Go.
- Built a concurrent sorting pipeline and a replicator utility to demonstrate practical applications of ParV2 in real-world scenarios.
