Overview
Michael Marquez works with teams on architecture, security, and engineering discipline, drawing on three decades of production experience and the systems built at Crumby Labs, including Bitcrumb and Tapin Wallet. That includes helping teams think clearly about where AI-assisted development helps and where it needs a human decision in front of it, the same case made in AI Is Not Your Architect.
Services
Blockchain
Protocol design and implementation, from consensus and identity to token systems, grounded in production work on Bitcrumb.
Distributed & Scalable Systems
Clustering, consensus, service decomposition, and fault-tolerant architecture for systems that need to keep working and keep growing.
Web & Mobile Applications
Full-stack architecture for production web and native mobile apps, including key management and encrypted storage where it matters, drawing on Tapin Wallet.
Augmented AI Engineering
Architecture discipline for teams building with AI coding tools, the practice behind AI Is Not Your Architect.
Security Consulting
Security review and threat modeling for systems handling identity, keys, or anything else that can't be quietly compromised.
Code Migration
Moving an existing codebase from one language or stack to another without losing what already works.
Team Building & Training
Structuring engineering teams, hiring guidance, and workshops based on the methodology in AI Is Not Your Architect.
