A real-time web application for bulk-purchasing NFTs from multiple marketplaces at the best price. The front end is built with React and Next.js, and the back end utilizes a combination of Node.js, Redis, and PostgreSQL, which is hosted on Google Cloud Platform (GCP). The application aggregates data from blockchain with Optimism and various marketplaces to deliver a seamless user experience.

An API that allows developers to automatically retrieve phone calls and payment information, with user consent, for credit scoring and behavior analysis. The API was built with Go and Rod and utilizes Puppeteer to automate crawling and extracting data from HTML websites.

A Web3 platform to whitelist and mint the ERC1155 NFT. I developed several smart contracts using Solidity for serving purposes of whitelisting by locking the token and minting the ERC1155 music token with the metadata on IPFS, including the sale contract. I also conducted functional and security testing for the platform.

A Web3 React website for authenticating the user wallets to verify their NFT ownerships and bring them special privileges. I was the full-stack developer on the project, utilizing the new standard EIP-4361 login with Ethereum to let users sign the message with clarity.

An Elixir and React Native-based mobile application that connects to the top exchanges around the world to enable people to buy and sell cryptocurrency at a better rate without the friction of payment and technical barriers.

I led the development of the mobile application, back end, and the team to develop the smart order routing algorithm to find the real-time best rate from cryptocurrency exchanges worldwide.

We launched the alpha version to the private group of testers; the application seamlessly processed the transactions over $1 million with stability and security. The application successfully traded and securely kept the customers' assets.

Our team believed the solution would solve the serious challenges in the cryptocurrency industry on user experiences and best price discovery.

The SCB Open Banking Hackathon is a competition organized by the Siam Commercial Bank that aims to offer innovative financial ideas with advice and guidance from the partnership.

Our team won the biggest prize in the competition with the crypto lending product that hybrid traditional finance. The idea is that people who have a lot of assets do not necessarily have good credits, especially investors and entrepreneurs. Thus, it is hard for them to access a good loan.

So we built the proof-of-concept platform that facilitates the new risk model where users can collateralize the crypto assets in any form and take the loan in the form of fiat currency instead.

I believe that the innovative approach to bridge the traditional and future of finance, slick user experience, and seamless integration with the banking application led us to impress the judges and win the competition.

As I believe in the future of blockchain, I don't want anyone to miss the opportunity to learn, build, and invest in such incredible technology. But the problem is that it is tough for people—even developers—to truly understand the technology. And most importantly, ensure enough understanding of the security and fundamentals to protect themselves from many threats that make them lost their assets.

So I spent some of my time sharing the knowledge in webinars or blogs to help people understand blockchain technology more, strengthening the community for a better future together.
