Nathan Foster is a founder and engineer with 10 years of hands-on experience building production web and AI systems, currently shipping Fostera, an AI companion platform focused on persistent memory. He designs and implements full-stack solutions end-to-end—from memory extraction, embeddings, and RAG to multi-LLM orchestration, PWA clients, and Stripe monetization—often as a solo builder. Nathan has driven major cost and reliability wins in production (including ~90% token-cache savings and multi-provider failover across 12+ LLMs) and brings disciplined practices like eval-harness regression testing and observability as first principles. Prior roles include Principal Front-End at Yieldmo and Staff engineer at Ranker, where he led high-traffic Next.js modernizations and test-driven rollouts. He pairs product instincts with engineering rigor—favoring cache-hit metrics and golden test sets over optimistic assumptions—and continues evolving his consumer AI product evenings and weekends from Lafayette, Indiana.
