Frontend Team Lead at Rubic who built its public API, now powering swaps in 160+ Web3 projects.
SpainWhat I'm looking for
At Rubic, I built the public API from scratch, from design and implementation through rollout, rate limiting, and abuse protection. It now powers swap integrations in 160+ Web3 projects.
I also designed and owned Rubic's TypeScript SDK for cross-chain and on-chain trading across EVM and non-EVM chains. I architected a privacy-preserving cross-chain transfer system spanning DEX aggregation and on-chain privacy protocols.
As Frontend Team Lead, I led a frontend team of up to five and drove its roadmap, planning, and releases. I moved the codebase to an Nx monorepo and introduced agentic development across the team.
Earlier at Rubic, I rewrote the web app on Angular and helped expand provider coverage across chains. At Neo Stack Technology, I built data-heavy enterprise interfaces, and at EleKom I built and maintained a WordPress Multisite network.
