Summary
Douglas Fields is an engineering leader and repeat founder with two decades of experience building secure, scalable distributed systems and fintech products from startup to acquisition. He combines hands-on backend architecture and coding (LISP and Haskell user since 1990) with proven operational leadership—scaling teams globally, instituting CI/CD and modern DevOps, and guiding products through audits, GDPR and security compliance. His background spans high-performance trading and risk systems, blockchain-enabled real estate fintech, and large-scale messaging and e‑commerce platforms that handled billions of emails monthly. At companies from his own startups to Mastercard and Google, he’s led cross-functional teams to deliver elegant, fault-tolerant systems while mentoring engineers. Notably, he built Puresend into a profitable exit and has repeatedly re-architected legacy systems into continuous-delivery engines that improved throughput, reliability and monitoring.
