About Me

Who I am & what I do

I am a full-stack engineer passionate about building intuitive, performant software with a strong emphasis on clean code and maintainable architecture. From web platforms and mobile apps to data pipelines and AI tools, I specialize in crafting end-to-end solutions that scale through thoughtful design and best practices.

My journey in software development began when I was introduced to Scratch in middle school. I fell in love with it immediately and haven't stopped coding since! I continued to code in high school, eventually choosing to go to Penn State where I developed the majority of my skills and knowledge in computer science and software engineering, with a particular focus on writing clean, readable, and maintainable code. Since then, I've been expanding my skills through both professional work and personal projects, always striving to follow best practices and produce high-quality software.

Outside of coding, I find balance through various outlets, primarily swimming, running, and journaling. Physical fitness is a big part of my life, and I find it helps me stay focused and balanced. I find it very satisfying to set big goals and work steadily toward them. In Summer 2024, I completed an Ironman 70.3, and lately I've been eyeing a full marathon and/or open water swim races. Additionally, when I have the time, I like to produce music and play video games, and when I have the money, I love to travel!

Experience

Where I've worked & what I've done

I've contributed to a range of projects from AI development to educational roles. My professional experience includes working with cutting-edge technologies and developing solutions that bring real value.

Software Engineering Contractor
MAY 2024 — JUL 2025

Built internal tooling and harnesses to evaluate LLM-generated code for clients including Google, Meta, and OpenAI

Automated compilation, execution, linting, and test orchestration to measure pass@k and correctness

Contributed to Google's Stitch UI code-generation workflow by building prompt templates and evaluation harnesses that improved component fidelity and layout accuracy

Designed data pipelines for training/eval (schema/versioning, validation, deterministic sampling) that replaced manual review with scripted checks and reduced turnaround time

Instrumented metrics and built dashboards (syntax/style error rates, test failure modes); triaged failures with research/eng partners to accelerate model iteration cycles

Authored seed datasets and context frameworks emphasizing clean, idiomatic solutions and explicit performance trade-offs

Enforced schema normalization and deduplication at ingest via scripted checks for data quality assurance
