Humor Retriever

Available for 2026 Summer Internship

Generally Speaking

I am a high-signal communicator. In a world of noise, I value brevity, precision, and the strategic use of humor to bridge gaps between cross-functional teams. I like to call myself a Humor Retriever — loyal to the joke, always chasing the laugh, and firmly believing that if you can’t explain a complex neural network with a smile, you don't understand it well enough.

My academic journey began with a fascination for Physics, which evolved into a BEng and BS in Food Science & Engineering. Far from just "cooking", this path allowed me to apply rigorous engineering principles — thermodynamics, fluid mechanics, and process control — to volatile biological systems at CAU and Cornell. It taught me how to manage the inherently chaotic, a skill that translates surprisingly well to building deterministic software out of non-deterministic LLMs.

After three years in the biotech industry navigating the complexities of operations and project management, I recognized that AI automation is the ultimate lever for engineering impact. Now, at Penn Engineering, I am merging my industry-hardened system discipline with deep software training. I view this master's degree not just as a career pivot, but as a systematic upgrade of my toolkit to engineer autonomous agents and robust backend systems.

Currently, I am focused on building out agentic workflows, custom protocols, and full-stack AI applications. I prepare for the worst, architect for the best, and debug everything from prompt latency to distributed pipelines. If you’d like to discuss MCP, RAG optimization, or tell a joke that’s actually funnier than mine, feel free to reach out. I monitor my inbox with the latency of a high-frequency trading system.

More About Me

Soccer and Food

I thrive on structure and discipline, yet I’m easily won over by the simple things in life: quality sleep, a great soccer match, and the occasional windfall of free food.

Long before I immersed myself in science, my world was defined by the 19x19 grid of a Go board. As a semi-professional player, I became one of the top-ranked female players in my province by the age of 10, a milestone built on years of strategic thinking and relentless practice. When AlphaGo emerged, it didn't discourage me; instead, it shifted my fascination from the game to the machine. Transitioning into tech felt less like changing paths and more like continuing the same high-stakes match, just against a different kind of opponent.

To keep my mental focus sharp, I maintain a strict physical routine. I’ve traded high-impact sports for high-consistency swimming to preserve my joints, 25km freestyle every month. For me, swimming is the ultimate "low-latency" activity for sustained cognitive performance. I draw constant motivation from athletes like Fan Zhendong, Zhang Weili, and Kylian Mbappé. Their resilience reminds me that dedication is a universal language, whether you're on the pitch or at a terminal.

I’m a staunch advocate for the "early to bed, early to rise" lifestyle, having maintained such a biological clock that hasn’t wavered for almost two decades. During my focused hours, I usually have Khalil Fong’s mellow tracks on loop. I’ve always admired his calm professionalism and kindness, qualities I strive to bring into my own development work.

Beyond the screen, I’m a certified BLS provider. Earning that certification was a grounding reminder that impact exists outside of grades and deadlines. It’s about being prepared to contribute when every second actually counts.

Cooking is my final ritual for balance. Having spent years in Food Science, I treat my body like a high-stakes lab experiment: alcohol is strictly blacklisted, while sugar, dairy, and caffeine are on permanent probation. Crafting healthy, grounding meals is how I stay connected to my roots. However, all my dietary principles vanish the moment someone mentions "free food". I have a secret, undeniable weakness for Basque cheesecake and triple chocolate cookies.

As I said, Soccer is the latest spark in my professional journey. This May, I am joining the Accreditation Operations Support team for the FIFA World Cup 2026 in Philly, bringing my obsession with process optimization to the world’s biggest stage. Having managed complex biotech pipelines and medical protocols, I treat high-volume credentialing like a mission-critical deployment: security standards are the source code, and workflow efficiency is the non-negotiable KPI. It is the ultimate collision of my technical discipline and my lifelong love for the "beautiful game." However, my professional composure is highly vulnerable to a perfectly executed bicycle kick; I might be verifying your identity, but my heart is definitely on the pitch.
