Summary

Senior🎓
Top SchoolJacob Matthews is a Senior Software Engineer with 11 years' experience building scalable backend systems and improving developer productivity across startups and larger companies like Airbnb and NexHealth. He specializes in Ruby on Rails and PostgreSQL performance, having led projects that cut test times from an hour to five minutes and dramatically reduced DB load during high-growth phases. As a former Principal Engineer at ChartMogul he redesigned core analytics data structures for ~100x query improvements and open-sourced a fair queuing Sidekiq plugin adopted by other teams. Jacob blends technical depth—JIT work for Ruby and low-level performance tuning—with a people-first approach, mentoring juniors, hiring, and leading teams. Based in Wellington, he brings entrepreneurial insight from co-founding a subscription startup and a preference for solving product and team problems as much as code.
