When you learn about someone working hard, growing fast, and giving back to their community at the same time, their story feels inspiring right away. That is exactly how the journey of Jennifer Gu feels. She is a young software engineer who works at Databricks in San Francisco, and she has already built an impressive path through tech, startups, and student leadership. Her story is easy to relate to because it shows how passion, community, and steady effort can open new doors.
Jennifer Gu describes herself as someone who loves tech, startups, and creating community. This already tells you a lot. She is not someone who only codes. She is someone who builds things, helps people, and brings groups together. Even today, while working on the data platform at Databricks, she still stays connected to the communities that helped her grow, especially her strong Cornell network.
Early Life, Education, and Growing Interest in Tech
If you look at her background, you can see that Jennifer Gu focused on learning from the very beginning. She studied Computer Science at Cornell University and earned both her BS and her Master of Engineering in CS. She also added Applied Economics, which makes her outlook even stronger because she understands both the tech side and the business side of any idea.
During her time at Cornell, she was not only a student. She became a real part of the campus tech world. She worked as Course Staff for many classes, including Machine Learning (CS 4780), Database Systems (CS 4320), Discrete Structures (CS 2800), Object-Oriented Programming (CS 2110), and Introduction to iOS Development (CS 1998). This meant she helped students learn and guided them through important concepts, which also strengthened her own skills.
You can also see how much she loves community because she volunteered with Girls Who Code, Women in Computing at Cornell, and CodeDay Bay Area. These roles show her interest in supporting young coders, creating safe spaces for women in tech, and helping students build confidence. Even before college, she was already active in tech events and competitions, especially through DECA and the Technovation Challenge.
First Tech Experiences and Early Projects
The journey of Jennifer Gu in tech began long before Databricks. She started building projects early, and many of them were creative and hands-on. One of her first projects was a Music Reactive LED Strip, where she learned Arduino programming, soldering, and circuit design. It was a small project, but it shaped her interest in blending hardware, software, and design.
Later, she helped create Crisis Nexus, a project built with JavaScript and Firebase. This was more than just an app. It was a mock startup aimed at crisis relief, and it placed as one of the semifinalists in the U.S. in the Technovation Challenge. This kind of national recognition showed that she had both technical strength and strong leadership skills, even at a young age.
As she moved into college, her projects became even more meaningful. She worked on Volume, an app that lets students explore content from Cornell publications. She used GraphQL networking, SwiftUI, and PDFKit to build it. She also worked on Eatery, the Cornell dining app used by over 6,000 students every month. These apps were open-source and loved by the community, which matches her passion for community-focused tech.
Becoming a Leader at Cornell AppDev
A big part of the story of Jennifer Gu is her role in Cornell AppDev. This student-run engineering team became one of the most important communities in her life. She started as an iOS developer, then became a Product Manager, then Vice President, and finally President of the entire team.
Being the President of AppDev is not a small thing. This team releases real apps with thousands of users, works with real organizations, and teaches students how to ship high-quality software. Jennifer became one of the main people guiding new developers, planning product ideas, and keeping the team’s culture positive and strong.
She even calls AppDev “the most impactful community” she has ever been part of. And when you look at her work there, it is easy to see why.
PulseFit: The App Built by Jennifer Gu to Make Fitness Simple
One of the most interesting projects created by Jennifer Gu is PulseFit, a clean and easy fitness app designed to help people stay active without stress. The idea behind PulseFit is simple: fitness should feel easy, friendly, and fun. Many fitness apps feel complicated or overwhelming, but PulseFit does the opposite. It gives users a calm and simple way to track their workouts, build good habits, and stay motivated.
A Simple App With a Clear Goal
PulseFit was built with one goal in mind: help people move every day. Jennifer Gu wanted an app that removes pressure and makes fitness feel welcoming. PulseFit focuses on simple tracking, daily routines, and small wins. Instead of pushing users with hard training plans, the app encourages steady progress.
Users can log their workouts, set personal goals, and view their growth over time. Everything is easy to read and easy to understand. This matches Jennifer’s belief that tech should feel friendly, not confusing.
Designed With Real People in Mind
PulseFit has a clean and soft design. The colors are gentle, the layout is simple, and the buttons are clear. This comes from Jennifer’s background in building community-focused apps like Eatery and Volume. She understands how to build tools that people will actually use every day.
PulseFit also includes short reminders that feel supportive, not stressful. A friendly message might say, “A short walk counts too!” or “You’re doing great — keep moving!” These small touches help users feel encouraged, not judged.
Made for All Fitness Levels
One reason PulseFit stands out is that it works for everyone. Whether someone is new to fitness or already active, the app adjusts to their pace. Jennifer Gu wanted the app to feel like a personal guide rather than a strict coach.
New users can start with light goals such as stretching or walking. More advanced users can track strength training, running, or longer workouts. PulseFit never compares users to others — it focuses on personal progress.
Built With Care and Strong Technical Skill
Behind its simple design, PulseFit uses strong engineering. With Jennifer’s experience in Swift, SwiftUI, iOS development, and product design, the app runs smoothly and loads fast. Her background in building apps for thousands of students helped her design PulseFit in a way that feels reliable and stable.
Just like her other projects, PulseFit is shaped by her love for community and her belief that technology should make life better. Fitness apps often feel too intense, but PulseFit feels like a kind friend.
Projects That Show Her Creativity and Skill
When you look at the list of apps created by Jennifer Gu, you can see how much she enjoys building helpful tools. One project, Parakeet, is an AI language learning app. It shows her interest in AI and simple learning tools. Another project, the OCaml Melody Generator, shows her fun side because it creates music using code.
But some of her strongest work came from Cornell AppDev. She helped build Eatery, the app that shows dining menus for thousands of students each month. She worked on Volume, the app that shares student publications. She also built apps like Circus and score!, which each won awards such as “Best UI” and “Best Overall” at the AppDev Hack Challenge.
These projects prove something important about Jennifer Gu: she does not just learn for herself. She builds products that help a community. She builds tools that make students’ lives easier. This is why AppDev became such a big part of her story.
A Leader With a Strong Sense of Community
It is easy to see why so many people admire Jennifer Gu. She leads with kindness. She teaches with patience. She learns with curiosity. During her years at Cornell, she became a leader in many groups, including AppDev, Women in Computing at Cornell, Alpha Kappa Psi, and the Cornell National Organization of Business Engineers.
She did not choose these groups because of titles. She chose them because they matched her values. She cares about helping people grow. She cares about supporting women in tech. She cares about teaching new developers. And she cares about creating a space where everyone feels welcome.
Many students say that leaders like her make hard classes easier and make big goals feel possible. Her teaching roles in machine learning, databases, iOS development, and other CS courses show how much trust the school placed in her.
