Yoni Rapoport is a CTO and software engineer with 10+ years of experience who co-developed a unique, fully automated legacy-to-.NET migration technology that preserves functionality and UI while producing clean C# code. He blends deep object-oriented and low-level Windows experience (C#, C++, Win32) with web and database expertise (ASP.NET, Java, SQL Server, Oracle) and a TDD/Agile development mindset. As Firefly Migration’s technical lead he has overseen production-grade automation that removes manual recoding and avoids development freezes or retraining. He also contributes to open-source full‑stack tooling—adding a WebSQL data provider to the remult project—demonstrating practical work across client-side and server-side data layers. Based in Israel, Yoni pairs hands-on engineering with product-focused leadership to modernize legacy systems at scale.
