PROFILE

Simon Meier

Over seven months, contributed to the hyperledger-labs/splice and splice-wallet-kernel repositories by building and refining backend systems for blockchain wallet integration, token standards, and disaster recovery. Focused on API development and smart contract design using DAML, Scala, and Protobuf, the work included implementing zero-fee transaction features, enhancing observability with granular metrics, and streamlining developer onboarding through improved documentation and CI/CD pipelines. Addressed reliability by fixing wallet proxy withdrawal logic and legacy transaction decoding, while also simplifying token APIs and strengthening disaster recovery runbooks. These efforts improved system reliability, developer productivity, and operational readiness for blockchain-based financial applications.
