At DV Labs (Obol Network), I led engineering across backend services, distributed protocols, smart contracts, and infrastructure. I implemented HotStuff consensus alongside QBFT and designed a pluggable architecture for dynamic consensus selection.

At Chainlink, I designed and implemented the initial version of Chainlink Functions across backend services, APIs, smart contracts, and production observability. Earlier, I designed and launched MODE.IO’s end-to-end messaging platform and built backend and infrastructure systems at Deutsche Bank and Microsoft.
