I'm Sergi — a Senior Solidity Engineer working on compliant real-world asset (RWA) tokenization.
At Tokeny (part of Apex Group) I work on the ERC-3643 / T-REX stack — the leading standard for compliant security tokens — together with ONCHAINID and the on-chain compliance modules that enforce identity, eligibility, and transfer rules at the protocol level. It's a narrow, high-stakes corner of the space: institutional tokenization has to be correct and legally enforceable, with no room for the usual "move fast" tradeoffs.
My focus is increasingly on smart-contracts, dApps and AI Agents — bringing tokenization to the next level.
Around the core protocol work I'm a full-stack engineer (React / Next.js, Node, FastAPI, The Graph subgraphs, Dune analytics, LangGraph / LangChain), with a prior background in product management and internationalization across multinationals and startups.
