@katanasato
Senior Software Engineer specializing in Ethereum, Solidity, and full-stack web3 systems.
United StatesWhat I'm looking for
I am a Senior Software Engineer with 7+ years across consulting and product teams, focused on Ethereum, Solidity smart contracts, and full-stack delivery of web3 and data-intensive systems. I translate ambiguous business goals into secure, production-ready architectures, delivering discovery-to-pilot workstreams, proofs-of-concept, and production integrations across blockchain, APIs, and cloud.
I have led end-to-end Ethereum engagements, built smart contracts and event indexing, and driven security and gas-efficiency reviews while scaling backend services, CI/CD, and observability. My work includes contributions to OpenSC (BCG X + WWF), UP42 geospatial marketplace, and TrustExplorer continuous proof-of-reserves—demonstrating impact on provenance, tokenization, and real-time attestation products.
