Elmer Furukawa

I’m a blockchain developer with 7 years of experience architecting and implementing blockchain solutions across industries. I’ve worked as an interoperability and DeFi engineer on bridging protocols across chains including Polygon, Cosmos, and zkSync.

In recent work, I architected an atomic-swap bridge connecting multiple chains and built/customized on-chain modules (reward, vote) and off-chain components (relayer, processor). I implemented gasless transactions and pre-compiled contracts to integrate with app modules, then led a small engineering team to deliver a cross-chain bridge that improved user convenience by 10%. I also developed modules around attestations (FHE, TEE for SGX, MEV) and resolved 5+ Cosmos SDK governance dependency issues while spinning up and managing networks with Sentry Node using DevOps tooling such as Ansible, Terraform, and Prometheus.

Earlier, I participated in audits of cross-chain dApp contracts on Ethereum and built inbound, outbound, and proof modules using the Cosmos SDK, introducing a state machine to improve system debugging and management. I analyzed 10+ user stories and architectures for fintech and financial services use cases, working with well-known systems such as Plaid and Wyre, and I delivered a blockchain-based supply chain solution that reduced costs by 15% while improving transparency and efficiency. I also bring strong software engineering discipline from building back-end and DevOps infrastructure with Rust/Golang, TDD/BDD, Jenkins CI/CD, Kubernetes/EKS, and AWS.
