About Us

Calling all programmers, designers, makers and leaders! TeenHacks LI is Long Island’s premier 24-hour high school hackathon, by students, for students. Take part in group collaboration, interesting workshops, sweet prizes, and more. Get ready to meet new people and have an amazing time. Join us as we build the future!

Founded by Jeffrey Yu and Wesley Pergament, we bring together the brightest students across the tri-state area to engage in “collaborative coding.” We hope to build a hacker community here on Long Island, with an emphasis placed on innovation and entrepreneurship.


What is a hackathon?

It's a place where programmers, engineers, designers, and entrepreneurs come together to build an awesome project in 24-hours. We provide the venue and food, you bring the creativity. Get ready to learn, build something cool, and meet new people. Check out this article by Dave Fontenot to learn more! What is a Hackathon?

What if I’m a beginner?

Do not worry. TeenHacks LI encourages students of all levels to come! In addition, we will have workshops throughout the hackathon as well as mentors available to answer any of your questions.

Who can attend?

All high school students are welcome to attend. If you are older or younger and still want to participate as a hacker, shoot us an email. If you're older, we welcome you to sign-up as a mentor!

Does it cost anything?

TeenHacks LI is completely free, thanks to our generous sponsors! This will include food, swag, and awesome prizes. If you’re looking for travel reimbursement for TeenHacks LI, apply to Execute Big’s Travel Grant program - especially useful for our folks from around the nation who’d need trains/busses/flights to get here! We want to make it as accessible as possible for you to get here!

What if I don't have a team?

In the beginning, we’ll have a team formation session to make sure you’re not alone. You can have teams as large or small as you want, but only teams of 2-4 will be eligible for prizes.

What should I bring?

You should bring your student ID, laptop, phone, chargers, sleeping bag, deoderant, toothbrush, as well as any hardware or materials you may need for your project. Nothing hazardous or illegal.

Our Core Team

Wesley Pergament, Co-Founder and Executive Director

Wesley is currently a senior at Jericho High School and has always loved to create and build. His natural curiosity has led him into the world of Raspberry Pi’s and Arduino sensors as he enjoys tinkering with hardware. Through hackathons, Wesley fell in love with the community of makers and as a result, worked passionately to bring this atmosphere to Long Island. Additionally, he enjoys the business side of things as well and TeenHacks LI was the perfect combination of the two. Above all, Wesley constantly strives to learn new things and meet more people every day.

Eva (Yi) Xie, Director of Marketing and Graphics

Eva is currently a senior at Bronx Science. She is a huge fan of STEM and art. These both matter to her because art provides her infinite possibilities in the imagination while STEM enables her to explore and practice these possibilities in the real-world setting. During her first Hackathon event ever - in TeenHacks LI, she was fascinated with how both were combined together and actualized something even bigger. Thus far, she hopes to engage more youths, especially beginners, to get involved in this community that she is truly passionate about. Meanwhile, she believes in STEM progress would be the key to making the world a better place for everyone.

Austin George, Director of Programming

Austin George is a senior at Great Neck South High School, with a passion for creating. Through this, he has grown a strong interest in both art and computer science. Whether it be painting the school mural or coding games for his friends, he’d much rather be on the side of the creator than the consumer. Throughout his high school career, he has strived to share this enthusiasm with others by tutoring students at local coding classes and sharing his experiences with the people he meets at hackathons like TeenHacks LI. This year, as Director of Programming, he is seeking the prospect of working with a few major companies in the tech industry that would be willing to host workshops to improve the overall hacker experience.

She also has a strong love of music and plays multiple instruments. When she first got involved with TeenHacks she enjoyed the friendly coder environment and collaborating with new people on different projects. This drove her to further become involved in the team and now hopes to open doors to unprivileged students through STEM and music.

Karen Li, Director of

Karen is currently a senior at Methacton High School. She is very passionate about STEM, participating in various science fairs and engineering competitions. Her interest in technology grew after taking Java and robotics classes at her high school. This led her to explore this passion at hackathons. After attending TeenHacks LI last spring, she joined TeenHacks LI's core team to further immerse herself in the hacking community and to provide others with the opportunity to learn and create. She also hopes to encourage more young women to pursue STEM through her high school's Girls Who Code Club, teaching programming to middle school girls.

Rachel Woo, Co-Director of
Campus Ambassadors

My name is Rachel Woo and I am currently a freshman at Great Neck South High School. I am very passionate about computer sciences as well as STEM. During my free time, I like to work on different coding projects, play field hockey and research more about new technological developments. Attending the past two hackathons has inspired me to spread the CS community and influence more people to become involved with new innovations that can impact our futures. I hope to encourage more students in all different grades to immerse themselves with STEM activities and, as a director, enhance the hackathon experience.
