I am a blockchain developer with 7 years of experience building, architecting, and implementing blockchain solutions across multiple industries. My background includes work on interoperability, DeFi, and bridging protocols across chains such as Polygon, Cosmos, and zkSync.
I have strong experience designing cross-chain systems and on-chain/off-chain components, including atomic-swap bridges, relayers, processors, and custom modules. I have also worked on gasless transactions, pre-compiled contracts, and blockchain infrastructure for production environments.
My technical strengths include Rust, Golang, Solidity, JavaScript/TypeScript, Cosmos SDK, Substrate, Web3, and cloud/devops tooling such as AWS, GCP, Kubernetes, Terraform, Ansible, Jenkins, and Prometheus. I am comfortable working across backend engineering, blockchain architecture, and infrastructure operations.
In recent roles, I led engineering efforts, collaborated on architecture reviews, performed code reviews, and helped solve complex dependency and governance-module issues. I have also contributed to audits, supply chain blockchain systems, fintech integrations, and performance improvements in distributed systems.
Earlier in my career, I worked as a backend developer in the banking sector, where I focused on software quality, CI/CD pipelines, test strategy, and zero-downtime infrastructure. This experience strengthened my ability to build reliable systems and work effectively in Agile teams.
I hold a Bachelor of Computer Science from Osaka Aoyama University. I am based in Canada and am interested in roles where I can continue building scalable blockchain platforms, cross-chain infrastructure, and secure decentralized applications.
Architected an atomic-swap bridge connecting multiple chains including Bitcoin, Solana, Ethereum, and Aeternity. Developed and customized on-chain modules and off-chain components. Implemented gasless transactions and built pre-compiled contracts to interact with app modules.
Led a small team of 5 engineers to implement a cross-chain bridge. Customized and developed modules related to attestation, FHE, TEE, and MEV. Solved dependency issues while customizing the Cosmos SDK governance module. Managed a network with Sentry Node architecture using Ansible, Terraform, and Prometheus.
Participated in audits of cross-chain dApp contracts on Ethereum. Developed inbound, outbound, and proof modules based on the Cosmos SDK. Contributed to architecture reviews and code reviews, analyzed user stories, and implemented blockchain solutions for fintech and supply chain use cases. Built backend systems using Rust and Golang and used SubGraph for data fetching.
Improved software quality using TDD and BDD, worked in Agile development, and maintained effective team communication. Restructured software architecture to reduce overhead costs. Created the initial test strategy and increased test coverage. Built CI/CD pipelines with Jenkins and set up zero-downtime infrastructure using Kubernetes and EKS. Managed AWS DevOps infrastructure for eCommerce sites.
