📌 Note: While my early career (2003–2015) focused on enterprise software with ASP.NET WebForms, AJAX, and system architecture, I made a deliberate pivot to blockchain in late 2017. Since 2018, I have been building exclusively in the Web3 space — from full crypto exchanges (Coinatik) to DeFi ecosystems (Unilab) and AI-blockchain platforms (AIConnective). My 25+ years of software engineering provide a deep foundation for writing secure, scalable, and production-grade smart contracts.
