Hi, I'm Junho Yeo

Welcome to my site. I'm a 20-yo generalist hacker, shaping the 2nd/3rd web. Sometimes a designer and dreamer, I just like to build things. Now I'm preparing the infrastructureโ€”insight, followers, and capitalโ€”for a bigger dream.

2023~

IBCX

Product Manager/Frontend Developer 2022.10 ~ 2023.02

The Cosmos ecosystem was founded on the belief that the future of blockchain lies in specialized chains for specific applications, and this vision has already come to fruition with the successful deployment of numerous AppChains serving millions of users.

Until now, people who believed in Cosmos bought $ATOM, but it lacked direct representation of the potential of other projects being built. That is why we created $IBCX, the Interchain Basket of Coins.

As the first fully-collateralized index token for Cosmos, $IBCX reflects the overall growth rate of the entire ecosystem, effectively making investments for Cosmonauts. Governed by the ION DAO, $IBCX is a secure and easily deployable asset comprising a basket of leading Cosmos coins weighted by market capitalization.

You can learn more about $IBCX and the ION DAO at index.ion.wtf.

Twitter

Elon hired George Hotz to fix Twitter search, and he opened a competition for open-source developers/designers to implement the new search feature without private code access. I submitted my solution and received a mention.

realGeorgeHotzGeorge Hotz ๐Ÿ€@realGeorgeHotzNov 23, 2022

This is the interview.

Build this feature. You don't get source access. Link the GitHub and license it MIT.

Looking for a one liner I paste in my JavaScript console to enable good "from:"

000

Should hot modify existing Twitter search box, not looking for a demo on a different page.

Looking for more than just tokenization of the word "from", that's just a part of it. It should fix the suggestions to be your followers, etc...things you might actually type.

Build a script people will want to inject into their Twitter page because it's useful, not a demo.

Bento

Founder ~

I developed dashboard apps for protocols and wallets on a part-time basis, but I quickly became disappointed with their limitations.

Many services were closely tied to a specific layer-1 chain, as they were either built by the same team or funded by the same venture capital firms. This often resulted in these products struggling to expand beyond their own ecosystem and not being able to meet the needs of users who required multi-chain functionality and scalability.

In addition, many of these products were closed-source software, which centralized development and required users to rely on the team to add support for their desired protocols.

Dissatisfied with the available dashboard options, I decided to create my own open-source dashboard. I began building the app and assembled a team to work on it, named the resulting product "Bento." You can learn more about Bento and try it out for yourself at bento.finance.

ZEP Studio

Led Development for Hackathon

ZEP is a platform that allows creators to build interactive and productivity apps using its SDK, ZEP Script. However, creating apps with it can be challenging for those without prior development knowledge, and the testing process can be inefficient.

That's where our block coding editor comes in. ZEP Studio simplifies the process of creating ZEP Script-based apps and offers three key advantages - no code or developers required, fast testing and easy deployment, and efficient previews - making it easy for anyone to create their own virtual world.

ZEP Studio uses Google's Blockly as its back-end, while improving the user experience with a block-coding editor interface similar to Scratch. Whether you're a seasoned developer or a complete beginner, it has everything you need to create amazing apps on the ZEP platform.

Manythings is a blockchain builder group, leading and participating in numerous blockchain/crypto projects. Raised Seed Investment in Nov 22 with US $50M Valuation.

DeFi Protocols

I contributed to the product side of various DeFi protocols, working part-time on their design and frontend development.

One of the protocols I worked on, which powered DeFi savings and payment services for DApps, maintained an average TVL of $330M before the UST depeg incident and was later acquired.

In addition, I have contributed to another protocol in stealth, with a total trading volume of over $3B (ongoing).

Toss

Part-time Frontend Developer

As a part-time frontend developer at Toss, a fintech unicorn currently valued at over $7.4B and the largest unicorn startup in South Korea, I built the landing page for NEXT 2021, a large-scale recruitment event with gamification(achievements).

I also contributed to the frontend of Simplicity 21, an internal design conference, and maintained web products such as Toss Feed 3.0, Home, and Notice.
