I've built and owned production systems across SaaS, fintech, and blockchain for 26 years. At Sellerboard, I built the account-sharding service behind registration and login across multiple backends and databases, re-synchronising roughly 100k accounts daily.
Previously, I led development of SGS, a blockchain-based currency and payment system, for six years. I work hands-on with PHP, Laravel, relational databases, REST APIs, queue-driven backends, Docker, and CI/CD, and I use agentic coding tools in production every day.
