Summary
👤
SeniorJacob Sullivan is a Seattle-based software engineer with 10 years of full-stack experience building high-performance web and trading systems. He has shipped latency-sensitive features at Coinbase Futures and led optimization efforts at Red Violet that cut average request latency by 30% and p99 by 50%, nearly eliminating timeouts. Comfortable across React, Vue, TypeScript, Node.js and .NET, he repeatedly improves frontend responsiveness and memory use—once reducing an investor dashboard’s session memory from 80MB to 30MB and slashing Android app cold-start time by 70%. He pairs hands-on coding with mentoring and cross-functional collaboration, and brings a pragmatic background in both product startups and large enterprise domains such as financial services and logistics. A former bootcamp instructor and solo-founder of a web tools shop, he combines strong delivery instincts with an eye for measurable performance wins.
