Site Code

Small business owner and blockchain engineer transitioning to full-time software development. I combine 18 years of hands-on operational experience — built and ran a multi-property construction company with 16 employees — with a formal computer programming background and experience building a DeFi liquidity management platform. Ready to bring that same end-to-end ownership to serious blockchain and web3 work.
