I'm kwiss, a founder and developer based in France with a deep care for design.
Trained in both programming and design, I started as an art director before moving into UX/UI, product building, and full-stack development. I've always worked in close collaboration with the people around me, leading engineering teams, shaping processes, and shipping products from the first wireframe to production.
I'm currently co-founding a new venture, still in stealth, building AI systems for a profession where precision isn't optional. Think agentic workflows, retrieval, and fine-tuned models applied to documents that actually matter. More on that soon.
I also lead Cosmic Taco, a design and development studio crafting brands and interfaces for DeFi products like Ekubo, Vesu, or AVNU. On the DeFi side, I'm actively digging into onchain vaults and the emerging role of risk curators, exploring how capital allocation, strategy design, and trust get rebuilt onchain. It's an area I keep coming back to and expect to build in.
Before that, I served as CTO at DY Protocol, an onchain options protocol at the crossroads of Morpho and Deribit, and co-founded Screenshotlabs, a web3 studio behind Game of Blocks, an onchain Ethereum game, Ark Project, an NFT marketplace protocol built on Starknet, and Everai, an anime-inspired NFT collection that built a strong community. I also ran Space Monkeys, an animation studio where I managed over 50 artists and worked with clients like Ubisoft.
On the side, I build my own AI agents, dev tools, and workflows to rethink how products get built. I care deeply about craft and about the people I build for, because nothing beats seeing something come to life.
