Subhajit Chaudhury
Solana-focused full-stack blockchain developer on a mission to reshape DeFi. Building lightning-fast dApps, scalable smart contracts, and intuitive user experiences on-chain. Deeply passionate about permissionless finance, capital-efficient protocols, and pushing Solana to its limits. Crafting the future of decentralized systems—where speed meets sovereignty.
About Me
I'm a self-made developer chasing mastery in the Solana ecosystem, but beyond the code, I'm a bathroom singer, a part-time poet, a moody guitarist, and someone who finds peace in sketching and soulful music. Every day is a step forward—through failures, late nights, and deep dives into code. I believe in showing up, pushing limits, and earning my place through hard work and consistent execution.

I've worked on a variety of projects, from simple websites to complex web applications. Here are a few of my favorites.
Carbon OnChain
Carbon OnChain
October 2025 - Present
Carbon on-chain brings carbon credits to the blockchain, making them transparent, traceable, and verifiable in real time. It allows companies to offset emissions by purchasing tokenized carbon credits through smart contracts. Each transaction is recorded immutably, ensuring accountability and reducing greenwashing. This bridges sustainability with DeFi — enabling open, auditable, and automated climate action.
