Simon contributed to the hyperledger-labs/splice-wallet-kernel and splice repositories, focusing on backend and smart contract development using DAML, Scala, and Java. He overhauled exchange integration documentation, implemented disaster recovery planning, and introduced wallet proxy features to enhance rights delegation and user experience. Simon enabled system-wide zero transfer fees in DAML modules, adding feature flags and comprehensive test coverage. He improved observability by exporting granular party metrics and optimized performance through parallelized activity marker conversion. His work included standardizing IDE integration for BSP code generation and refining database management, resulting in more reliable, maintainable systems with improved developer experience and operational transparency.

October 2025: Delivered cross-language developer experience improvements, observability enhancements, performance optimizations, and IDE integration fixes across splice-wallet-kernel and splice. Key changes align with business value by enabling robust Java integration references, improved transaction monitoring, richer per-party observability, higher throughput under load, and reliable BSP/IntelliJ codegen tooling.
