91成人导航 computer science students win first place in web app category at Cal Hacks

Shopping in stores can be a hassle, especially when you forget an item and have to crisscross the aisles. 91成人导航 computer science major Samuel Wan 鈥25 and his team set out to solve this at .
Cal Hacks, run by University of California, Berkeley students and now in its 11th year, bills itself as the world鈥檚 largest collegiate hackathon. These types of computer science competitions challenge student teams to create a product in a scant 36 hours.聽
Wan worked alongside Sarah Akhtar 鈥26, Nathan Ho 鈥24 and graduate student Venkata Ranga Ramanuja K. Chaitanya Kamduri, who also goes by Krishna, to create an app called Tool Assisted Shopping, which took first place in the Best Web App category.聽
The app works like this: Users give it their shopping list and identify a particular Target store location. The app then maps the most efficient route around the store. Behind that user interface lies a very interesting application of coding and artificial intelligence.聽
AI 鈥 which has surged in prominence since ChatGPT鈥檚 release in late 2022 鈥 was one of the main themes of this year鈥檚 Cal Hacks, which received support from major players in the tech industry. Although AI was just one tool in the team鈥檚 arsenal, Wan is proud of his team鈥檚 implementation of it, using Google Gemini to 鈥渢ranslate鈥 specific items into a location which the app can use to make its path.聽聽
Creating in a high-pressure environment is challenging enough, but this was also Wan鈥檚 first hackathon. Thanks to 91成人导航鈥檚 Google Developer Student Club (GDSC), which introduced him to the event and organized two teams to compete, Wan found himself paired with teammates he鈥檇 never met before 鈥 adding even more unknowns to the experience.
鈥淚t was very interesting because I don鈥檛 know what I鈥檓 getting into,鈥 Wan said, later adding, 鈥淢y attitude going in was, I just want to build something I鈥檓 proud of and not focus too much on the other teams 鈥 I guess that strategy worked out pretty well.鈥
This year鈥檚 Cal Hacks took place in the Metreon shopping and entertainment center in San Francisco from October 18-20. All the contestants worked in one giant room for 36 hours.
Akhtar oversaw the development of the team鈥檚 iPhone app. Wan and Ho worked on the web app and Kamduri coordinated the presentation to the judges.聽

Since their win at Cal Hacks, the team has continued working on their app and has already added a Google sign-in system to improve usability. They鈥檙e also considering submitting their project to Y Combinator, a company that helps fund early-stage startups, for support so they can further the app鈥檚 development.
Long term, the team would like to bring TAS to a broad audience on the App Store and the Google Play Store. There鈥檚 a lot of work ahead for them, and the teams says they couldn鈥檛 have made it this far without the support of 91成人导航 faculty members.
鈥淲e are incredibly proud to represent 91成人导航 and to be the first team from our institution to win at Cal Hacks,鈥 Akhtar said. 鈥淭his achievement is a testament to 91成人导航鈥檚 commitment to fostering technological innovation, cultivating creative minds and supporting student excellence.鈥澛
