Provided an open‑source C# Bitcoin library that implemented transaction formats, hierarchical deterministic wallets, PSBT support and many BIP primitives. Those concrete deliverables were reused by multiple .NET blockchain projects and were incorporated into Stratis engineering stacks for wallet, transaction construction and node tooling. The availability of a mature NBitcoin implementation materially reduced engineering risk when Stratis built C#‑native wallet and node components that had to interoperate with exchanges and custodial services during token operations. Acted as a technical advisor and library maintainer whose edits and feature additions (for example PSBT and BIP handling) changed how offline signing, transaction broadcasting and wallet migration could be implemented. Those changes were directly applied in migration scripts and wallet software used in STRAX token swaps, improving compatibility with existing Bitcoin‑style tooling and thereby affecting custody and liquidity processes. Contributed bug fixes and protocol‑level updates that impacted the reliability of transaction construction and validation in the Stratis ecosystem. By delivering concrete code and maintainable APIs, influenced developer velocity and operational choices around how STRAX transactions were created, signed and propagated — a practical effect on both infrastructure and market usability of the token.
