Rockstar🎓
Top SchoolJuan Ubeira is a Smart Contracts Lead with 13 years of engineering experience who transitioned from robotics, AR and firmware to building permissionless DeFi protocols on Ethereum. At Balancer he led a core smart-contracts team through the development and deployment of V3 core contracts and contributes to the balancer-v2 monorepo, focusing on deployment, testing and integrations like ERC4626 and chained approvals. An electronics engineer by training, he combines low-level systems rigor (embedded C, FreeRTOS) with modern Solidity practices, enabling robust on-chain primitives such as AMMs and composable pool hooks. He has a track record of leading cross-functional teams, mentoring engineers, and shipping developer-friendly platforms that prioritize DX for builders. Active in open source, his past contributions include ROS/ROS2 libraries and Android robotics components, reflecting a knack for interdisciplinary problem solving. Based in Argentina, he brings a pragmatic, research-informed approach to designing permissionless financial infrastructure.
