2025 Mini Projects

This service was built to be used as promotional booth content for a club fair event at my university.

It asks multiple-choice questions about lifestyle preferences and open-ended questions about music preferences, then an LLM recommends music tailored to each person based on grouped responses.

For rapid development and accessibility, I built it as a web app using a familiar tech stack.

It was operated for 3 days from 10 Mar to 12 Mar, and 70+ people tried it.

Built at the BUIDL AI 2025 Hack.

During the hackathon, we gained hints from interviews with Web3 marketers and built a marketing solution that captures fast-changing real-time Web3 trends.

It parses live trends from communities such as Reddit and X, analyzes trend flow with an LLM, combines that with predefined user (company) information through Upstage’s Document Parsing AI, and extracts personalized marketing insights through Near AI’s AI Agent.

Won 2nd Place in Upstage Track and received a $1k prize.

Built at the Inha SW Net-Zero hackathon on the themes of environment and low power consumption.

While thinking about ways to reduce electricity usage, we realized that replacing the home appliances people use most often with low-power models can create a large impact.

We believed people need a clear incentive to switch to low-power products, so we designed a price comparison platform that presents the “true lowest price” by adding the maintenance cost of power-inefficient products to the product price.

It crawls power usage information for products on the market and calculates costs, then analyzes labels of products users currently own with Azure’s Vision AI and uses RAG for cost comparison. It also breaks down user queries into tokens with OpenAI LLMs to support natural-language querying instead of condition-based filtering used in traditional price comparison platforms.

Won 3rd place and received a ₩500k (≈$330) prize.

Built as part of XRPL Campus Ambassador activities at BlueNode, a blockchain society at Inha University.

Inspired by the “Post-it blind date” trend in university events, we planned an onboarding project that could be used in real campus events while also helping general students easily understand the concept of a DEX.

User profiles reflecting tastes and preferences are issued as gender tokens on Ethereum and placed in a liquidity pool contract. When a user from the opposite gender requests a match, different suitability scores are applied based on pool conditions, then opposite-gender tokens are swapped and deposited tokens are burned to complete the swap.

Through this, users can easily understand the DEX model of managing and swapping tokens through a pool.

This project was selected as an XRPL Korea Ambassador project and was presented in a session.

Built at the NTU X BASE Web3 Hackathon.

To help financially support independent musicians we had long been interested in, we designed a service that applies NFTs’ key strength—strong community building— to the music ecosystem.

When artists upload music, visual art is generated with SOGNI AI’s image generation AI and minted as NFTs on the Base chain. Musicians can trade these NFTs on the marketplace to build a community, and by distributing part of their profits on-chain to holders, they can build a strong fan base through an ongoing win-win relationship.

Although it did not win an award, it was selected by SOGNI AI as a grant recipient project and received a token grant.

Afterward, based on Musual, we produced the exhibition project Do We Dream of Posthumanity?.

Built at the Surreal World Assets Buildathon 2.

To solve the compensation issue for traditional “petfluencers” who receive no reward even when their pets become famous memes, along with the lack of transparency in the ad industry, we built a petfluencer ad platform combining petfluencers with InfoFi.

When petfluencers select and upload pet product ads provided by the platform, the service rewards them on-chain in real time based on quality and payout rate. Each petfluencer can issue a memecoin and gain additional activity-based rewards, and rewards are shared with holders to strengthen the community. Each petfluencer’s IP is uniquely managed on the Story chain to prevent theft.

Although this project did not win an award, the promotional video for the service won in the Generative Video track and received a $1k prize.
