Blockchain Developer

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.
