Welcome! I'm Yohanes Willy Agusta
Fueled by a deep passion for Web3 and the decentralized future, I specialize in transforming bold, forward-thinking ideas into secure, transparent, and user-sovereign digital experiences. Whether it's designing intuitive dApp interfaces, architecting resilient smart contract ecosystems, or integrating blockchain technologies, I strive to build products that empower users.
The Core of My Codebase
Where I Deliver Value
FullStack Developer
I build complete web applications from the ground up with React, TypeScript, and JavaScript, to setting up the engine behind it all with Node.js and Express.js. I handle the whole package, making sure it's solid and easy to use.
Smart Contract / Web3 Developer
When it comes to blockchain and building decentralized applications, I write the core smart contracts in Solidity that is integrated to the user interface. I aim to ease people to use them, whether it's for something new in DeFi, DAO, or NFT.
Digital Marketing & Data Analytics
Beyond coding, I bring a solid data analyst and 5+ years background in digital marketing and data. This helps me not just build cool full-stack or Web3 apps, but also understand how to get them in front of the right people and see if they're actually working well.
