Drop is a mobile-first web app that turns New York City into a live board game where physical items like disposable cameras and toys drift from stranger to stranger. Built for urban explorers and romantic wanderers, the app lets you drop and pick up items and monitor a drop's entire journey across the city while staying completely anonymous.
“Google AI Studio is a surprisingly friendly entry point for non-developers, proving that you don’t need a traditional coding background to bring a complex spatial and interactive idea to life.”
Helps job seekers prep for interviews!
“It added in suggestions to our build that we didn't even consider. It was a great addition!”
Drift City is a community-driven web app that turns everyday urban spaces into an ongoing game of real-world object pass-along. Built for urban explorers, scavengers, and curious city dwellers, it tracks physical items—like a disposable camera or a rubber duck—as strangers move them from corner to corner across New York City. The cool part? You get to watch real-world human connections trace interactive, living vector paths across a digital map in real time.
“Letting Gemini rephrase my prompts for AI Studio was helpful.”
Nomad Quest is an interactive travel etiquette and cultural survival simulator. Instead of reading dry travel blogs or memorizing standard phrases, users are dropped into immersive "24-hour" city scenarios where they must navigate real-world dilemmas, cultural nuances, and language barriers. It gamifies global citizenship—rewarding players with passport stamps and respect points as they learn how to navigate new cultures without making costly, awkward tourist mistakes.
“The "Homework" Trap: It was surprising how quickly educational content can accidentally feel like a school assignment (the "Quizlet effect"). We realized that simply having good information isn't enough; the delivery has to be dynamic. By introducing bouncy, engaging animations and restyling the scenarios to feel like an adventure game rather than a multiple-choice test, the exact same educational”
Nestwork matches small groups of compatible strangers in NYC - by shared interests like tech, wellness, trekking, or being new to the city - and sends them a curated invitation to a real evening out, itinerary and venues included. Every member is ID-verified before their first Nest, so meeting strangers actually feels safe. Once you RSVP, a scoped group chat opens just for your Nest, active through the event and archived after - no lingering inbox, no swiping.
“We assumed the hard part would be the matching algorithm. It wasn't - the hard part was realizing trust, not compatibility, was the real blocker to strangers meeting up. The ID verification step ended up being the feature people cared about most.”

“Recently, I have been working on a project related to smart home, so I chose a similar direction.”
ForgeIQ is a multimodal engineering intelligence platform powered by Gemini that analyzes technical drawings and component images. Users upload engineering artifacts and receive structured AI-assisted reviews including design analysis, manufacturability (DFM), material recommendations, preliminary FMEA, quality inspection checklists, and prioritized engineering recommendations. ForgeIQ helps engineers evaluate designs faster while keeping the human engineer in the decision loop.
“I was surprised by how much structured engineering insight Gemini could generate from a single technical drawing. The biggest challenge was designing prompts that produced engineering-focused analyses rather than generic image descriptions.”
Scout is an AI apartment-hunting agent for NYC renters. It turns plain-English preferences into listing searches, ranks and enriches the matches, and organizes next steps in one map-first tracker. It can also draft broker outreach so renters can move quickly while staying in control of what gets sent.
“I expected the AI to be most useful for writing messages, but its biggest value was translating messy human preferences into precise search filters. Once Scout understood requests like “a no-fee two-bedroom under $5,000,” the rest of the workflow became dramatically simpler.”
Food Hunt allows you to pick your food when you don't know what to eat for lunch/dinner. The website will prompt you to enter basic information such as your address, the radius of the website, and your budget. Then it will ask you select the kind of food that you want right now.
“It was a very tough project to do within a short amount of time. But we managed to finish on time”
TeamPulse streamlines team collaboration by automatically assigning tasks to the most suitable team members. It allows teams to define each member's role, skills, and weekly availability, then intelligently matches unassigned tasks based on expertise and capacity. This helps teams, especially large or remote ones, delegate work more efficiently and complete projects more effectively.
“What surprised me most during development was how seamlessly role-based AI task delegation transforms project planning. Rather than just assigning tasks randomly, evaluating member skills, weekly capacity hours, and target deadlines using Gemini AI produces surprisingly nuanced, practical workload recommendations.”
This project is an Autonomous AI Escape Room Engine that leverages Yann LeCun’s JEPA architecture and Gemini 2.5 Flash to create procedurally generated 3D games. It utilizes a multi-agent framework where specialized modules like the Configurator and World Model collaborate to simulate the physics and logic of your environment. Players select unique themes and scenarios which the engine then transforms into an interactive, real-time 3D world using the Three.js library. The system moves beyond sim
“Mapping Yann LeCun’s JEPA paper directly to game master mechanics revealed that modular brain agents (Configurator, World Model, Critic, Actor) naturally eliminate AI hallucinations by simulating spatial physics before narrative generation. We were surprised by how seamlessly an LLM orchestrator could generate real-time 3D spatial JSON protocols while maintaining strict object permanence across ga”
