Ali Olfat is a backend-focused Senior Software Engineer based in San Francisco with 9+ years of experience building high-impact, production-grade systems across fintech, consumer, and data platforms. He has driven large-scale migrations and architectural initiatives—most notably extracting DoorDash’s fraud monolith into microservices, cutting critical DB CPU by 60%, halving latency, and delivering over $1.5M/year in fraud savings. Comfortable across Kotlin, Python, Go, Java and data streaming tech like Flink, Kafka, Redis and Cassandra, he designs real-time aggregation and feature-serving systems and led Featureform’s engineering before its acquisition by Redis. Beyond code, he’s a pragmatic team-builder who established strategy, mentored hires, ran learning programs, and coordinated cross-team efforts to move complex projects forward. He also channels creativity into freelance photography/videography, bringing a storyteller’s eye to problem solving and product thinking.
