Summary
🤩
Rockstar🎓
Top SchoolSunny Aggarwal is a blockchain-focused founder and engineer with a decade of experience building decentralized infrastructure and developer tooling from San Francisco. As Co‑Founder of Sikka and a longtime Cosmos ecosystem contributor, he blends protocol-level backend work (cosmos-sdk, Osmosis AMM modules) with front-end UX improvements for widely used projects like the Osmosis frontend. He’s equally comfortable refactoring core error handling and adding new DeFi message types as he is polishing React components to surface cross-chain token data. A former Tendermint research scientist and Epicenter co‑host, he pairs academic rigor in cryptoeconomics with a talent for communicating complex ideas to builders and users. Known for pragmatic architecture changes rather than flashy experiments, he quietly improves reliability and developer experience across major open-source blockchain stacks.
