Invisible Garden's first gathering ran for six weeks in the Nimman district of Chiang Mai. It was a residency: builders applied, a cohort was selected, and the people who came spent their days on Ethereum, zero knowledge proofs, and the tooling around them.

830 developers applied and 160 were accepted, 80 of whom came on site from more than 15 countries. Over 40 mentors ran 83 workshops between them, from Solidity fundamentals to ZKP compilers and MPC. Mentors came from the Ethereum Foundation, PSE, SECBIT and others, and taught in workshops, bootcamps, and one to one sessions.

Builders submitted 34 open-source projects and 22 graduated, scored by the mentors. The work covered dapps, ZK applications, biometric authentication with zero knowledge, encrypted voice chat, and cryptography research. The fellowship recognised the builders who carried the cohort, as academic and honorary fellows.

I’m a Solidity engineer with a deep focus on DeFi and NFT finance, driven by the belief that crypto empowers people by giving them full ownership and control over their assets. What excites me most about blockchain technology is its ability to cut out intermediaries and deliver solutions directly to users, fast. I love writing code that lives on-chain and my sweet spot is building complex, secure systems that feel intuitive and elegant for the people using them. I take an agile, hands-on approach to turn abstract ideas into functional decentralized applications offering users more agency, freedom, and delight in how they interact with digital value. I’ve had extensive experience deploying features securely to Mainnet, making sure everything reaches production with confidence and care. For me, it’s not just about writing smart contracts — it’s about building meaningful tools that push the space forward while keeping users at the center.
