👤
SeniorJeff Boulter is a seasoned staff tech lead and hands-on software architect with over two decades of experience building scalable, consumer-focused web services—from scrappy startups to billion-pageview platforms. Currently leading platform and CMS infrastructure at HubSpot, he’s driven large migrations (including a 500k-line Python-to-Java port) and built persistent storage services like HubDB to make CMS data behave like a spreadsheet-backed SQL store. He combines product intuition with deep backend chops—Java, HBase, CDN and CDN-driven petabyte asset pipelines—and has improved template tooling through contributions to the popular Jinjava project. His career track record includes launching high-impact products (LAUNCHcast, Yahoo! News/Weather) and founding engineering practices that scaled teams and revenue. Colleagues rely on him to identify unmet user needs and rapidly prototype robust, production-ready systems. Based in Lexington, MA, he still enjoys rolling up his sleeves to close gaps in complex web stacks.
